Changes in Release 1.6 (2019-03-19) ----------------------------------- - Work around TLSv1.3 PSK bug in (at least) OpenSSL 1.1.1b. - Fix static linking against recent OpenSSL versions. - Update our copy of libev from version 4.22 to version 4.25. The new release provides a few platform compatibilty fixes and small enhancements. - Apply a few minor improvements. Changes in Release 1.5 (2016-11-15) ----------------------------------- - Include an experimental NSCA-ng client module for Perl. - Link against libsystemd instead of libsystemd-daemon when using systemd version 210 or newer, where the latter library has been merged into the former. - Include the systemd.service(5) and systemd.socket(5) files with the release tarball. - Update our copy of libev from version 4.15 to version 4.22. The new release provides a number of bug fixes and small enhancements. Changes in Release 1.4 (2014-10-14) ----------------------------------- - Fix NSCA-ng's systemd support: Actually send the keep-alive packets expected by the watchdog. - Include an experimental NSCA-ng client module for Python. Changes in Release 1.3 (2014-07-15) ----------------------------------- - Make the server play nicely with systemd by providing a systemd.service(5) file and adding optional support for socket activation as well as other systemd features, such as watchdog supervision. When compiled with systemd support, the server enables these features automatically if it was socket activated. - Fix an issue that prevented compilation on (at least) Solaris and FreeBSD and caused a fatal startup error on (at least) NetBSD and OpenBSD. - Make sure our copy of FreeBSD's pidfile(3) code isn't used if the system provides it. The Autoconf test got this wrong in certain cases. - Don't buffer log output written to the standard error output. - Accept CRLF-terminated client configuration files. - Apply a few minor fixes. Changes in Release 1.2 (2013-11-06) ----------------------------------- - Let nsca-ng.cfg(5)'s `include` directive and nsca-ng(8)'s `-c` flag accept directory path names. If a directory is specified, read the server configuration from all `*.cfg` and `*.conf` files in the specified directory and all subdirectories. - Let the client's `-d` and `-e` flags accept C-style escape sequences, so that e.g. `-e '\n'` can be specified. Octal and hexadecimal numbers are also accepted. - Allow for specifying authorization settings outside of the `authorize` sections in nsca-ng.cfg(5) files. They will then serve as a fallback for `authorize` sections that don't define these settings. - Fix a race condition in the case where the command file is recreated after the NSCA-ng server had opened it. - Fix a crash of the client on 32-bit platforms that use 64-bit timestamps. - Don't use half-broken POSIX AIO implementations such as the one provided by Debian GNU/kFreeBSD 7. - Apply test suite fixes for GNU Hurd. - Update our copy of libev from version 4.11 to version 4.15. The new release provides a number of bug fixes and minor enhancements. - Apply some minor cleanups. Changes in Release 1.1 (2013-04-12) ----------------------------------- - Add chroot(2) support to the server. - Let the server accept `hosts` patterns in `authorize` sections. They're syntactic sugar for allowing host checks to be submitted (analogous to the `services` patterns for service check submissions). - Let the client ignore empty input lines. This fixes some corner cases where NSCA-ng's client didn't accept the same input as the client provided with the original NSCA package. - Add the `-e` client option, which allows for specifying a delimiter to use instead of the ASCII ETB character for separating check results. - Let the `invoke_check` script (provided in the `contrib` directory of the source tarball) survive plugin return codes other than zero. This should make the script slightly more useful :-) - Apply a few minor improvements. Changes in Release 1.0 (2013-03-06) ----------------------------------- - Actually use the POSIX AIO API if it's provided by the target system. The corresponding Autoconf test was broken since version 0.2. - When opening the command file, check whether it's a named pipe. If it's not, log a warning message and retry opening it later on. - Use the PSK-AES256-CBC-SHA cipher suite (instead of PSK-RC4-SHA) by default. - Apply various minor fixes and improvements. Changes in Release 0.3 (2013-02-25) ----------------------------------- - First public release. - Fix the server's `-s` and `-S` options. They were effectively ignored. - Mention the session ID in all log messages related to the TLS communication in order to ease debugging. - Apply a few minor cleanups. Changes in Release 0.2 (2013-02-19, Unpublished) ------------------------------------------------ - Accept non-numeric service check result status when matching against service patterns. - Don't accept spurious service check results. This could have happened when service patterns without host name part were specified. - Mention the session ID when refusing data. - Fix the client's `-s` option. It was effectively ignored. - Don't link the client against the libraries used only by the server. - Apply various minor cleanups. Changes in Release 0.1 (2013-02-08, Unpublished) ------------------------------------------------ - Initial release. nsca-ng-1.7/PROTOCOL000066400000000000000000000175101514241600000140700ustar00rootroot00000000000000The NSCA-ng Protocol, Version 1 =============================== > [Holger Weiss](mailto:holger@weiss.in-berlin.de) > February 2013 This is an informal description of the NSCA-ng Protocol, Version 1, used for transmitting "monitoring commands" from NSCA-ng clients to NSCA-ng servers. The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119][1]. Connection Initiation --------------------- The NSCA-ng server listens on TCP port 5668. As soon as an NSCA-ng client connects, a TLS handshake is initiated in order to establish a secure connection. Implementations MUST support TLS v1.0 as per [RFC 2246][2]. Also, the pre-shared key cipher suite `TLS_PSK_WITH_AES_256_CBC_SHA` as defined in [RFC 4279][3] MUST be offered by clients and accepted by servers. However, implementations MAY attempt to negotiate newer versions of the TLS protocol and/or other TLS cipher suites during the TLS handshake. When the TLS connection is established successfully, the client can initiate the first NSCA-ng request. All NSCA-ng data MUST be transmitted as TLS "application data". NSCA-ng Session --------------- Let's begin with an example where the client successfully transmits the `ENABLE_NOTIFICATIONS` command to the server (`C:` and `S:` indicate lines sent by the client and server, respectively): C: MOIN 1 Zm9vYmFy S: MOIN 1 C: PUSH 34 S: OKAY C: [1358980254] ENABLE_NOTIFICATIONS S: OKAY C: QUIT S: OKAY An NSCA-ng session is a sequence of one or more request-response pairs and zero or more "monitoring command" submissions. Requests and responses are CRLF-terminated lines (though implementations SHOULD also accept LF-terminated lines). The length of such a line MUST NOT exceed 1024 octets, including the CRLF-termination. Requests can only be issued by clients. A request consists of a case-insensitive four-character keyword followed by zero or more arguments. Keywords and arguments consist of printable US-ASCII characters, and are each separated by a single space character. Responses are emitted by servers and consist of a four-character keyword, which MUST be sent in all uppercase letters. The first request issued by the client (after establishing the TLS session) MUST be a `MOIN`, `PING`, or `BAIL` request. If the first request is a `MOIN` request, the last request issued by the client MUST be a `QUIT` or `BAIL` request. The remaining part of this document describes the possible client requests and server responses. "Monitoring command" submissions are described in the context of the `PUSH` request. MOIN Request ------------ Synopsis: MOIN Example: MOIN 1 Zm9vYmFy The client issues a `MOIN` request in order to negotiate the protocol `` and to specify a ``. The protocol `` is a positive decimal number, currently always `1`. The `` is an arbitrary string consisting of 2--64 printable US-ASCII characters. Clients SHOULD strive for uniqueness when generating the ``, though it's currently not referenced anywhere else in the NSCA-ng protocol. Implementations might mention the `` when logging connection data. If a `MOIN` request is sent, it MUST be the first request of an NSCA-ng session; except that the `MOIN` request MAY be retried with different parameters after the server replied to a `MOIN` request with a `FAIL` response. On success, the server replies with a `MOIN` response. See also: PING Request ------------ Synopsis: PING Example: PING 1 The protocol `` is a positive decimal number, currently always `1`. If a `PING` request is sent, it MUST be the first request of an NSCA-ng session; except that the `PING` request MAY be retried with different parameters after the server replied to a `PING` request with a `FAIL` response. On success, the server replies with a `PONG` response. The TLS connection is then shut down (cleanly) by both sides. PUSH Request ------------ Synopsis: PUSH Example: PUSH 42 The client issues a `PUSH` request in order to initiate a "monitoring command" submission. The "monitoring command" is expected to be in the format described in the Nagios documentation. The trailing newline character MUST be included, and the submitted "monitoring command" MUST NOT be CRLF-terminated. Newline characters within the "monitoring command" (except for the trailing newline) MUST be replaced with the literal string `\n`, and backslash characters MUST be escaped with another backslash. The `` parameter specifies the size of the "monitoring command" in octets, including the trailing newline character. On success, the server replies with an `OKAY` response. The client then transmits the "monitoring command". On success, the server replies with another `OKAY` response. The client MUST NOT submit multiple "monitoring commands" via a single `PUSH` request. The client MAY issue multiple `PUSH` requests per NSCA-ng session, though. NOOP Request ------------ Synopsis: NOOP Example: NOOP A `NOOP` request has no effect, with the exception that any connection timeout timers on the server SHOULD be reset. On success, the server replies with an `OKAY` response. QUIT Request ------------ Synopsis: QUIT Example: QUIT The client issues a `QUIT` request in order to close the NSCA-ng session. On success, the server replies with an `OKAY` response. The TLS connection is then shut down (cleanly) by both sides. BAIL Request ------------ Synopsis: BAIL ... Example: BAIL I'm feeling bad The client may transmit a `BAIL` request for any reason at any time. An arbitrary, human-readable `` MUST be specified. The TLS connection is then shut down immediately and unconditionally (but cleanly) by both sides. MOIN Response ------------- Synopsis: MOIN Example: MOIN 1 The server accepts a `MOIN` request by sending a `MOIN` response. If the server doesn't support the protocol `` suggested in the client's `MOIN` request, the server MUST either specify a supported protocol `` in the `MOIN` response or generate a `BAIL` response. In the former case, the client MUST either accept the protocol `` suggested in the server's `MOIN` response or generate a `BAIL` request. The protocol `` is a positive decimal number, currently always `1`. PONG Response ------------- Synopsis: PONG Example: PONG 1 The server replies to a `PING` request with a `PONG` response. The protocol `` is a positive decimal number, currently always `1`. The TLS connection is then shut down (cleanly) by both sides. OKAY Response ------------- Synopsis: OKAY Example: OKAY The server acknowledges the current client request or "monitoring command" submission by sending an `OKAY` response. FAIL Response ------------- Synopsis: FAIL ... Example: FAIL You're not authorized to submit this command The server sends a `FAIL` response to reject the current client request or "monitoring command" submission. An arbitrary, human-readable `` MUST be specified. The client then sends a new request. BAIL Response ------------- Synopsis: BAIL ... Example: BAIL I'm feeling horrible The server may transmit a `BAIL` response for any reason at any time. An arbitrary, human-readable `` MUST be specified. The TLS connection is then shut down immediately and unconditionally (but cleanly) by both sides.

This allows for submitting passive check results, downtimes, and many other [commands][1] to Nagios (or compatible monitoring solutions). NSCA-ng supports TLS encryption and shared-secret authentication with client-specific passwords (based on [RFC 4279][2]), as well as fine-grained authorization control. Prerequisites ------------- 1. [OpenSSL][3] 1.0.0 or newer is required for building NSCA-ng (as older releases don't support pre-shared key authentication). This is the only hard dependency of the NSCA-ng client. If the OpenSSL version provided by your operating system vendor is too old, you might want to build a private copy of OpenSSL and embed it into NSCA-ng. This could be done by running the `./build-aux/make-openssl` script, which downloads the most recent OpenSSL version and installs it into the NSCA-ng source tree. The `./configure` script (see below) will then pick that up automatically. 2. The NSCA-ng *server* also requires [libConfuse][4] 2.6 or newer. In order to embed a private copy of libConfuse into NSCA-ng, the `./build-aux/make-confuse` script could be run before calling `./configure`. 3. If [libev][5] 4.00 or newer is available and found by the `./configure` script, NSCA-ng will (by default) use it. Otherwise, a bundled copy of libev is embedded into NSCA-ng, so this dependency is optional. 4. Optional [systemd][6] integration code is added to the NSCA-ng *server* if systemd's `sd-daemon(3)` library is found. This can be disabled by specifying the `--without-systemd` option on the `./configure` command line. Installation ------------ If only the client should be built, issuing the following three commands in NSCA-ng's source directory should do the trick: $ ./configure $ make $ su root -c 'make install' This installs the NSCA-ng client into appropriate subdirectories of `/usr/local`. The installation process can be customized by setting environment variables and/or passing options to the `./configure` script. Some of the more frequently used `./configure` options include: * `--enable-server` Build and install the NSCA-ng server (in addition to the client, unless `--disable-client` is specified). * `--disable-client` Don't build and install the NSCA-ng client. * `--disable-posix-aio` Don't use the POSIX AIO API. By default, the NSCA-ng server will use the POSIX AIO API if available. * `--prefix=PATH` Install NSCA-ng into subdirectories of `PATH` instead of `/usr/local`. * `--with-confuse=PATH` Search for the libConfuse header files in `PATH/include`, and search for the libConfuse library files in `PATH/lib`. If this option isn't specified, `./configure` will look for libConfuse in a few typical locations. * `--with-ev=PATH` Search for the libev header files in `PATH/include`, and search for the libev library files in `PATH/lib`. If this option isn't specified, `./configure` will look for libev in a few typical locations; and if no usable version is found, a bundled copy of libev will be embedded into NSCA-ng. In order to force usage of the included copy, `--with-ev=embedded` can be specified; while `--with-ev=external` would disallow falling back to the bundled libev code. * `--with-openssl=PATH` Search for the OpenSSL header files in `PATH/include`, and search for the OpenSSL library files in `PATH/lib`. If this option isn't specified, `./configure` will look for OpenSSL in a few typical locations. For a full list of available options and environment variables, run `./configure --help`. See the file `INSTALL` for detailed installation instructions. Configuration ------------- The NSCA-ng client is configured using the `send_nsca.cfg(5)` file, the NSCA-ng server uses the `nsca-ng.cfg(5)` file. Examples of these files are installed if they don't already exist. > **Important:** Please set the permissions of the configuration files > appropriately to make sure that only authorized users can access them. A script such as `nsca-ng.init` (as provided in the `contrib` directory of this package) could be used to start and stop the NSCA-ng server. Usage ----- Please see the scripts in the `contrib` directory for various usage examples. NSCA Compatibility ------------------ The NSCA-ng client (`send_nsca`) is a drop-in replacement for the `send_nsca` binary provided with the original NSCA 2.x package in the sense that NSCA-ng's `send_nsca` accepts all input, command line arguments, and configuration files accepted by the original `send_nsca`. NSCA-ng clients cannot talk to NSCA servers (nor vice versa), but NSCA and NSCA-ng servers can happily run side by side, and they use different ports by default. Documentation ------------- Detailed information regarding the build and installation process can be found in the file `INSTALL`. The NSCA-ng usage and configuration is documented in the `nsca-ng(8)`, `send_nsca(8)`, `nsca-ng.cfg(5)`, and `send_nsca.cfg(5)` manual pages. The commands `send_nsca -h` and `nsca-ng -h` spit out short summaries of the available command line options. For each release, noteworthy changes are listed in the file `NEWS`. Feature additions which are planned for future releases are added to the `TODO` file. For copyright and license information, see the file `COPYING`. Support ------- Bug reports and patches can be sent to the list (no subscription required). For usage support, please subscribe to the list. See the [NSCA-ng][7] website for details.

Wish List Items for NSCA-ng --------------------------- - Let the server support command authorization based on host and service groups. This requires the server to actually parse the submitted commands, as oppposed to simply matching them against the user-supplied regular expressions. - Let the server support a `clients` or `sources` directive that allows the user to specify one or more subnets (globally and/or per-client). Connections from source addresses outside these subnets should be rejected. - Let the server support proxying of (selected or all) data (with `forward` blocks in the configuration, for example). - Support requests for status and configuration data in order to provide a full-blown remote API. - Let the client execute standard Nagios plugins directly (as an alternative to using a script such as `contrib/invoke_check`), and maybe provide a daemon mode with poor man's check scheduling (i.e., add `check_interval` and `retry_interval` directives to the client configuration). - If the server is not available, let the client queue commands and results using local storage and submit them as soon as the server comes up again. - Let the client talk to multiple servers. - Port the client to Microsoft Windows. - Create a client library with Perl (and maybe Python) bindings. Wish List Items for OpenSSL --------------------------- - Add IPv6 support to OpenSSL's `BIO_s_connect(3)` API, so that the client can use IPv6. (The server supports IPv6 already.) There's a [ticket][1] with a patch in OpenSSL's tracker, and a related [discussion][2] on the OpenSSL development mailing list. - Support NULL encryption TLS-PSK cipher suites as defined in [RFC 4785][3]. This should make it easier to use tools such as `tcpdump(8)` for debugging NSCA-ng sessions. There's an [older][4] and a [newer][5] patch in OpenSSL's tracker. - Support SHA-256/384 (and GCM) TLS-PSK cipher suites as per [RFC 5487][6]. Someone [played around with this][7] already.

All scripts except for `nsca-ng.init` allow for specifying the path to the `send_nsca.cfg(5)` file via `-c `. Other `send_nsca(8)` options can be specified by setting the environment variable `SEND_NSCA_ARGS`. All scripts print usage information when called with the `-h` option. * `acknowledge` Acknowledges a problem using `send_nsca(8)`. If the `-S` option is specified, a service problem is acknowledged; otherwise, a host problem is acknowledged. Example invocation: $ acknowledge -H www -S HTTP * `debug_server` Opens a raw TLS connection to the `nsca-ng(8)` server, sends any lines read from the standard input, and prints any server responses to the standard output. Requires `s_client(1)` from OpenSSL 1.0.0 or newer, and `xxd(1)`. Example invocation: $ debug_server -c /etc/send_nsca.cfg * `disable_notifications` Globally disables host and service notifications using `send_nsca(8)`. Example invocation: $ disable_notifications * `downtime` Schedules a host or service downtime using `send_nsca(8)`. If the `-S` option is used, a service downtime is scheduled; otherwise, a host downtime is scheduled. The start and end times are specified with the `-s` and `-e` options, respectively. They accept the same date string format as GNU `date(1)'s` `-d` option. Requires GNU `date(1)` or BSD `date(1)`. Example invocation (the `-s` and `-e` options could be omitted here, as these are their default values): $ downtime -H mail -S IMAP -s now -e +2hours * `enable_notifications` Globally enables host and service notifications using `send_nsca(8)`.

it had exactly the same bugs as the linux aio backend, * where some undocumented poll combinations just fail. fortunately, * after finally reaching the author, he was more than willing to fix * this probably in 5.6+. * k) overall, the *API* itself is, I dare to say, not a total trainwreck. * once the bugs ae fixed (probably in 5.6+), it will be without * competition. */ /* TODO: use internal TIMEOUT */ /* TODO: take advantage of single mmap, NODROP etc. */ /* TODO: resize cq/sq size independently */ #include #include #include #include #define IOURING_INIT_ENTRIES 32 /*****************************************************************************/ /* syscall wrapdadoop - this section has the raw api/abi definitions */ #include #include /* mostly directly taken from the kernel or documentation */ struct io_uring_sqe { __u8 opcode; __u8 flags; __u16 ioprio; __s32 fd; union { __u64 off; __u64 addr2; }; __u64 addr; __u32 len; union { __kernel_rwf_t rw_flags; __u32 fsync_flags; __u16 poll_events; __u32 sync_range_flags; __u32 msg_flags; __u32 timeout_flags; __u32 accept_flags; __u32 cancel_flags; __u32 open_flags; __u32 statx_flags; }; __u64 user_data; union { __u16 buf_index; __u64 __pad2[3]; }; }; struct io_uring_cqe { __u64 user_data; __s32 res; __u32 flags; }; struct io_sqring_offsets { __u32 head; __u32 tail; __u32 ring_mask; __u32 ring_entries; __u32 flags; __u32 dropped; __u32 array; __u32 resv1; __u64 resv2; }; struct io_cqring_offsets { __u32 head; __u32 tail; __u32 ring_mask; __u32 ring_entries; __u32 overflow; __u32 cqes; __u64 resv[2]; }; struct io_uring_params { __u32 sq_entries; __u32 cq_entries; __u32 flags; __u32 sq_thread_cpu; __u32 sq_thread_idle; __u32 features; __u32 resv[4]; struct io_sqring_offsets sq_off; struct io_cqring_offsets cq_off; }; #define IORING_SETUP_CQSIZE 0x00000008 #define IORING_OP_POLL_ADD 6 #define IORING_OP_POLL_REMOVE 7 #define IORING_OP_TIMEOUT 11 #define IORING_OP_TIMEOUT_REMOVE 12 /* relative or absolute, reference clock is CLOCK_MONOTONIC */ struct iouring_kernel_timespec { int64_t tv_sec; long long tv_nsec; }; #define IORING_TIMEOUT_ABS 0x00000001 #define IORING_ENTER_GETEVENTS 0x01 #define IORING_OFF_SQ_RING 0x00000000ULL #define IORING_OFF_CQ_RING 0x08000000ULL #define IORING_OFF_SQES 0x10000000ULL #define IORING_FEAT_SINGLE_MMAP 0x00000001 #define IORING_FEAT_NODROP 0x00000002 #define IORING_FEAT_SUBMIT_STABLE 0x00000004 inline_size int evsys_io_uring_setup (unsigned entries, struct io_uring_params *params) { return ev_syscall2 (SYS_io_uring_setup, entries, params); } inline_size int evsys_io_uring_enter (int fd, unsigned to_submit, unsigned min_complete, unsigned flags, const sigset_t *sig, size_t sigsz) { return ev_syscall6 (SYS_io_uring_enter, fd, to_submit, min_complete, flags, sig, sigsz); } /*****************************************************************************/ /* actual backed implementation */ /* we hope that volatile will make the compiler access this variables only once */ #define EV_SQ_VAR(name) *(volatile unsigned *)((char *)iouring_sq_ring + iouring_sq_ ## name) #define EV_CQ_VAR(name) *(volatile unsigned *)((char *)iouring_cq_ring + iouring_cq_ ## name) /* the index array */ #define EV_SQ_ARRAY ((unsigned *)((char *)iouring_sq_ring + iouring_sq_array)) /* the submit/completion queue entries */ #define EV_SQES ((struct io_uring_sqe *) iouring_sqes) #define EV_CQES ((struct io_uring_cqe *)((char *)iouring_cq_ring + iouring_cq_cqes)) inline_speed int iouring_enter (EV_P_ ev_tstamp timeout) { int res; EV_RELEASE_CB; res = evsys_io_uring_enter (iouring_fd, iouring_to_submit, 1, timeout > EV_TS_CONST (0.) ?

* c) well, linux as usual: the documentation lies to you: io_submit * sometimes returns EINVAL because the kernel doesn't feel like * handling your poll mask - ttys can be polled for POLLOUT, * POLLOUT|POLLIN, but polling for POLLIN fails. just great, * so we have to fall back to something else (hello, epoll), * but at least the fallback can be slow, because these are * exceptional cases, right? * d) hmm, you have to tell the kernel the maximum number of watchers * you want to queue when initialising the aio context. but of * course the real limit is magically calculated in the kernel, and * is often higher then we asked for. so we just have to destroy * the aio context and re-create it a bit larger if we hit the limit. * (starts to remind you of epoll? well, it's a bit more deterministic * and less gambling, but still ugly as hell). * e) that's when you find out you can also hit an arbitrary system-wide * limit. or the kernel simply doesn't want to handle your watchers. * what the fuck do we do then? you guessed it, in the middle * of event handling we have to switch to 100% epoll polling. and * that better is as fast as normal epoll polling, so you practically * have to use the normal epoll backend with all its quirks. * f) end result of this train wreck: it inherits all the disadvantages * from epoll, while adding a number on its own. why even bother to use * it? because if conditions are right and your fds are supported and you * don't hit a limit, this backend is actually faster, doesn't gamble with * your fds, batches watchers and events and doesn't require costly state * recreates. well, until it does. * g) all of this makes this backend use almost twice as much code as epoll. * which in turn uses twice as much code as poll. and that#s not counting * the fact that this backend also depends on the epoll backend, making * it three times as much code as poll, or kqueue. * h) bleah. why can't linux just do kqueue. sure kqueue is ugly, but by now * it's clear that whatever linux comes up with is far, far, far worse. */ #include /* actually linux/time.h, but we must assume they are compatible */ #include #include /*****************************************************************************/ /* syscall wrapdadoop - this section has the raw api/abi definitions */ #include /* no glibc wrappers */ /* aio_abi.h is not versioned in any way, so we cannot test for its existance */ #define IOCB_CMD_POLL 5 /* taken from linux/fs/aio.c. yup, that's a .c file. * not only is this totally undocumented, not even the source code * can tell you what the future semantics of compat_features and * incompat_features are, or what header_length actually is for. */ #define AIO_RING_MAGIC 0xa10a10a1 #define EV_AIO_RING_INCOMPAT_FEATURES 0 struct aio_ring { unsigned id; /* kernel internal index number */ unsigned nr; /* number of io_events */ unsigned head; /* Written to by userland or by kernel. */ unsigned tail; unsigned magic; unsigned compat_features; unsigned incompat_features; unsigned header_length; /* size of aio_ring */ struct io_event io_events[0]; }; inline_size int evsys_io_setup (unsigned nr_events, aio_context_t *ctx_idp) { return ev_syscall2 (SYS_io_setup, nr_events, ctx_idp); } inline_size int evsys_io_destroy (aio_context_t ctx_id) { return ev_syscall1 (SYS_io_destroy, ctx_id); } inline_size int evsys_io_submit (aio_context_t ctx_id, long nr, struct iocb *cbp[]) { return ev_syscall3 (SYS_io_submit, ctx_id, nr, cbp); } inline_size int evsys_io_cancel (aio_context_t ctx_id, struct iocb *cbp, struct io_event *result) { return ev_syscall3 (SYS_io_cancel, ctx_id, cbp, result); } inline_size int evsys_io_getevents (aio_context_t ctx_id, long min_nr, long nr, struct io_event *events, struct timespec *timeout) { return ev_syscall5 (SYS_io_getevents, ctx_id, min_nr, nr, events, timeout); } /*****************************************************************************/ /* actual backed implementation */ ecb_cold static int linuxaio_nr_events (EV_P) { /* we start with 16 iocbs and incraese from there * that's tiny, but the kernel has a rather low system-wide * limit that can be reached quickly, so let's be parsimonious * with this resource. * Rest assured, the kernel generously rounds up small and big numbers * in different ways (but doesn't seem to charge you for it). * The 15 here is because the kernel usually has a power of two as aio-max-nr, * and this helps to take advantage of that limit. */ /* we try to fill 4kB pages exactly. * the ring buffer header is 32 bytes, every io event is 32 bytes. * the kernel takes the io requests number, doubles it, adds 2 * and adds the ring buffer. * the way we use this is by starting low, and then roughly doubling the * size each time we hit a limit. */ int requests = 15 << linuxaio_iteration; int one_page = (4096 / sizeof (struct io_event) ) / 2; /* how many fit into one page */ int first_page = ((4096 - sizeof (struct aio_ring)) / sizeof (struct io_event) - 2) / 2; /* how many fit into the first page */ /* if everything fits into one page, use count exactly */ if (requests > first_page) /* otherwise, round down to full pages and add the first page */ requests = requests / one_page * one_page + first_page; return requests; } /* we use out own wrapper structure in case we ever want to do something "clever" */ typedef struct aniocb { struct iocb io; /*int inuse;*/ } *ANIOCBP; inline_size void linuxaio_array_needsize_iocbp (ANIOCBP *base, int offset, int count) { while (count--) { /* TODO: quite the overhead to allocate every iocb separately, maybe use our own allocator?

The .BR nsca\-ng (8) process reads configuration data from the file specified with .B \-c on the command line or from .IR @sysconfdir@/nsca\-ng.cfg . . .SS File Format . Zero or more global settings and one or more authorizations must be defined in the configuration file (see the .B Global Settings subsection and the .B Authorizations subsection, respectively). They may appear in arbitrary order. An authorization is specified using the .B authorize keyword followed by a (possibly quoted) client identity string and a brace-enclosed block of corresponding authorization settings. However, an authorization setting may also be specified as a global setting outside of these .B authorize sections. In this case, it serves as a global fallback for authorization sections that don't define the setting in question. . .PP Global settings and authorization settings are defined by specifying a variable name followed by an equals sign (\(lq=\(rq) and a value (or possibly a list of values). Values can be strings, integers, or floating-point numbers. Strings have to be enclosed in single or double quotes if they contain whitespace characters, hash mark characters, or literal quotation marks. Otherwise, quoting is optional. To specify a literal single or double quote in a string, either escape it by preceding it with a backslash (\(lq\\\(rq) or quote the string using the other quote character. A literal backslash must be preceded with a second backslash if the string is enclosed in double quotes. . .PP A variable can be set to the value of an environment variable by specifying .BI ${ FOO }, where .I FOO is the name of the environment variable. The same can be done by specifying .BI ${ FOO :\- bar }, except that in this case, the value .I bar will be assigned when the environment variable .I FOO is not set. . .PP Any whitespace surrounding tokens is ignored. Empty lines and comments are also ignored. Comments are introduced with a hash mark character (\(lq#\(rq) and span to the end of the line. If the last character of a line is a backslash (\(lq\\\(rq), the subsequent line is treated as a continuation of the current line (and the backslash is otherwise ignored). . .PP The special directive .BI include(\(dq file \(dq) tells .BR nsca\-ng (8) to treat the contents of the specified .I file as if those contents had appeared at the point where this directive appears. If a directory is specified instead of a .IR file , all files with a .I .cfg or .I .conf extension in this directory and all subdirectories will be included. Symbolic links are followed. . .PP In the following subsections, the type of each value is denoted after an equals sign in angle brackets. . .SS Global Settings . The .BR nsca\-ng (8) server recognizes the following global variables. . .TP \fBchroot\fP\ =\ <\fIstring\fP> . On startup, perform a .BR chroot (2) operation to the specified directory. By default, .BR nsca\-ng (8) does not call .BR chroot (2). If this directive is used, the .BR command_file , .BR pid_file , and .B temp_directory must be specified relative to this directory. . .TP \fBcommand_file\fP\ =\ <\fIstring\fP> . Submit monitoring commands to the specified path name. This should be the named pipe .SM (FIFO) that Nagios (or a compatible monitoring solution) checks for external commands to process. The default is .IR @localstatedir@/nagios/rw/nagios.cmd . The specified value will be overridden if .BR nsca\-ng (8) is called with the .B \-C option. . .TP \fBlisten\fP\ =\ <\fIstring\fP> . Bind to the specified .SM IP address or host name. The default setting is \(lq*\(rq, which tells .BR nsca\-ng (8) to listen on all available interfaces. A colon (\(lq:\(rq) followed by a service name or port number may be appended to override the default port (5668) used by the .BR nsca\-ng (8) server. The specified value will be ignored if .BR nsca\-ng (8) is called with the .B \-b option, of if it is socket activated by .BR systemd (1). . .TP \fBlog_level\fP\ =\ <\fIinteger\fP> . Use the specified log level, which must be an integer value between 0 and 5 inclusive. A value of 0 tells .BR nsca\-ng (8) to generate only fatal error messages, 1 adds non-fatal error messages, 2 adds warnings, 3 additionally spits out every submitted command (plus startup and shutdown notices), 4 also logs each message sent or received at the protocol level, and 5 generates additional debug output. The default log level is 3. The specified value will be overridden if .BR nsca\-ng (8) is called with the .B \-l option. . .TP \fBmax_command_size\fP\ =\ <\fIinteger\fP> . Refuse monitoring commands (including check result submissions) which are longer than the specified number of bytes. Setting this variable to 0 tells .BR nsca\-ng (8) to accept commands of arbitrary length. The default value is 16384. . .TP \fBmax_queue_size\fP\ =\ <\fIinteger\fP> . Don't queue more than the specified number of megabytes worth of monitoring commands while Nagios isn't running (or not reading the command file). When the amount of available data exceeds this threshold, the queued data is thrown away. If this variable is set to 0, .BR nsca\-ng (8) queues an unlimited amount of data (until it exits due to running out of memory). The default value is 1024 (i.e., 1 gigabyte). . .TP \fBpid_file\fP\ =\ <\fIstring\fP> . During startup, try to create and lock the specified file and write the process .SM ID of the .BR nsca\-ng (8) daemon into it. Bail out if another process holds a lock on that file. By default, no such .SM PID file is written. The specified value will be overridden if .BR nsca\-ng (8) is called with the .B \-p option. . .TP \fBtemp_directory\fP\ =\ <\fIstring\fP> . Write temporary files to the specified directory. Temporary files are only written if clients submit very large commands (which cannot be written to the named pipe atomically). It is recommended to specify a directory which resides on a memory file system. By default, .I /tmp is used. . .TP \fBtimeout\fP\ =\ <\fIfloating\-point\fP> . Close the connection if a client didn't show any activity for the specified number of seconds. If this value is set to 0.0, .BR nsca\-ng (8) won't enforce connection timeouts. The default setting is 60.0 seconds. . .TP \fBtls_ciphers\fP\ =\ <\fIstring\fP> . Limit the acceptable .SM TLS-PSK cipher suites to the specified list of ciphers. The format of the string is described in the .BR ciphers (1) manual. By default, the ciphers in the list .SM \f(CWPSK-AES256-CBC-SHA:PSK-AES128-CBC-SHA:PSK-3DES-EDE-CBC-SHA:PSK-RC4-SHA\fP will be accepted. . .TP \fBuser\fP\ =\ <\fIstring\fP> . Switch to the specified user, and to the groups the user belongs to. This is done early on startup: after the configuration file has been read, but before the listening socket and (possibly) the .SM PID file are created. By default, .BR nsca\-ng (8) runs with the privileges of the invoking user. . .SS Authorizations . As mentioned above, an authorization section is introduced with the .B authorize keyword and a client identity field followed by a brace-delimited block of one or more authorization settings. A client provides its identity during the connection handshake. The server uses the provided identity string for looking up the .B authorize section applicable to the client. The corresponding section, if any, defines the authentication and authorization settings for the client in question. If no section explicitly defined for this client identity is found, but a section for the special client identity \(dq*\(dq (including the quotes) is defined, this section is used as a fallback. Note that no other wildcard characters are available, and that the \(lq*\(rq character has no special meaning in the client identity field except when specified exactly as described. . .PP Within the brace-delimited block of an authorization section, values may be assigned to the variables listed below. The pattern strings assigned to the .BR commands , .BR hosts , and .B services variables are .SM POSIX \(lqextended\(rq regular expressions, but with an implicit \(lq^\(rq at the beginning and \(lq$\(rq at the end of the patterns. Multiple patterns can be specified as a brace-enclosed, comma-separated list; check results and commands will then be accepted if they match any of the specified patterns. Commands and check results will be rejected unless these settings authorize the client to submit them. . .TP \fBcommands\fP\ =\ <\fI(list of) string(s)\fP> . Match the specified regular expression(s) against submitted monitoring commands and accept commands that match any of these expressions. The patterns are matched against the full command string supplied by the client, .I except for the leading bracketed timestamp and any whitespace following that timestamp. . .TP \fBhosts\fP\ =\ <\fI(list of) string(s)\fP> . Match the specified regular expression(s) against the \(lqhost name\(rq field of client-supplied .SM PROCESS_HOST_CHECK_RESULT commands and accept such commands if they match any of these expressions. . .TP \fBpassword\fP\ =\ <\fIstring\fP> . Reject connections from clients that don't use the specified password. This setting is mandatory. . .TP \fBservices\fP\ =\ <\fI(list of) string(s)\fP> . Match the specified regular expression(s) against the \(lqservice description\(rq field of client-supplied .SM PROCESS_SERVICE_CHECK_RESULT commands and accept such commands if they match any of these expressions. If a specified string includes one or more at signs (\(lq@\(rq), only the part preceding the last of these at signs is matched against the \(lqservice description\(rq field. The part following this at sign is used as a separate pattern which is matched against the \(lqhost name\(rq field of the same command. A service check result is then accepted only if both matches succeed for a given command. . .SH EXAMPLES . The .B @sysconfdir@/nsca\-ng.cfg file might look similar to the following example. . .PP .RS .nf .ft CW . user = "nagios" chroot = "/var/nagios" # Other paths are relative to this one! command_file = "/rw/nagios.cmd" pid_file = "/run/nsca-ng.pid" temp_directory = "/dev/shm" listen = "monitoring.example.com:5668" tls_ciphers = "PSK-AES256-CBC-SHA" log_level = 3 max_command_size = 65536 max_queue_size = 128 timeout = 15.0 # # Authenticated "root" clients may submit arbitrary check # results and any other monitoring commands (see: # ). # authorize "root" { password = "g3m25sMCUAO4NecZGld1H4xcJ9uDWvhH" commands = ".*" } # # Authenticated "checker" clients may submit arbitrary check # results, but no other commands. # authorize "checker" { password = "ilzNanlE9XjMLdjrMkXnk09XBCTFQrj5" hosts = ".*" services = ".*" } # # Authenticated "web-checker" clients may submit check results # for arbitrary services on hosts whose names begin with "www". # authorize "web-checker" { password = "m2uaIWwiq3AIqN55m3QdjwptkU1Q4Oov" services = ".+@www.*" } # # Authenticated "nsca-checker" clients may talk to the NSCA-ng # server, but may not submit anything to Nagios. # authorize "nsca-checker" { password = "ceOKwxpz14lKXroC4yUjJZbov6VAyKuT" } # # Other authenticated clients may submit check results for the # "disk", "swap", and "load" services on arbitrary hosts. # authorize "*" { password = "awHW5vxr3DcA9EvcUC9T3a90QfEexsWd" services = { "disk", "swap", "load" } } . .ft P .fi .RE . .SH CAVEATS .

The .B nsca\-ng server makes the Nagios command file accessible from remote systems. This allows for submitting passive check results, downtimes, and many other commands to Nagios (or compatible monitoring solutions). The communication with clients is .SM TLS encrypted and authenticated using pre-shared keys (as per .SM RFC 4279). The .B nsca\-ng server supports per-client passwords and fine-grained authorization control. . .PP The server process rereads its configuration file when it receives a hangup signal .SM (SIGHUP) by executing itself with the name and arguments it was started with. . .PP When compiled with .BR systemd (1) support, the .B nsca\-ng server auto-detects whether it was socket activated. If so, it behaves as if the .BR \-F option was specified, while it ignores the .BR \-b option and the .B listen setting in the .BR nsca\-ng.cfg (5) file. The .B nsca\-ng server supports .BR systemd (1)'s .B notify process startup type as well as the .B WatchdogSec feature (see the .BR systemd.service(5) manual). . .SH OPTIONS . .TP .BI \-b\ listen . Bind to the specified .I listen address or host name. The default setting is \(lq*\(rq, which tells .B nsca\-ng to listen on all available interfaces. A colon (\(lq:\(rq) followed by a service name or port number may be appended in order to override the default port (5668) used by .BR nsca\-ng . If this option is specified, the .B listen setting in the .BR nsca\-ng.cfg (5) file is ignored. . .TP .BI \-C\ file . Submit monitoring commands into the specified .IR file . This should be the named pipe .SM (FIFO) that Nagios checks for external commands to process. By default, .B nsca\-ng submits commands into .IR @localstatedir@/nagios/rw/nagios.cmd . This option takes precedence over the .B command_file setting in the .BR nsca\-ng.cfg (5) file. . .TP .BI \-c\ file . Read the configuration from the specified .I file instead of using the default configuration file .IR @sysconfdir@/nsca\-ng.cfg . If a directory is specified instead of a .IR file , the configuration will be read from all files with a .I .cfg or .I .conf extension in this directory and all subdirectories. Symbolic links are followed. . .TP .B \-F . Don't detach from the controlling terminal, and write all messages to the standard error output (unless the .BR \-s option is specified). . .TP .B \-h . Print usage information to the standard output and exit. . .TP .BI \-l\ level . Use the specified log .IR level , which must be an integer value between 0 and 5 inclusive. A value of 0 tells .B nsca\-ng to generate only fatal error messages, 1 adds non-fatal error messages, 2 adds warnings, 3 additionally spits out every submitted monitoring command (plus startup and shutdown notices), 4 also logs each message sent or received at the protocol level, and 5 generates additional debug output. The default log .I level is 3. If this option is specified, the .B log_level setting in the .BR nsca\-ng.cfg (5) file is ignored. . .TP .BI \-P\ file . During startup, try to create and lock the specified .I file and write the process .SM ID of the .B nsca\-ng daemon into it. Bail out if another process holds a lock on the .IR file . By default, no such .SM PID .I file is written. This option takes precedence over the .B pid_file setting in the .BR nsca\-ng.cfg (5) file. . .TP .B \-S . Write all messages to the standard error output and (with the exception of startup messages) to the system logger. This option may only be specified together with the .B \-F option. . .TP .B \-s . Send all messages to the system logger, except for startup messages. This is the default behaviour (unless the .B \-F option is specified). . .TP .B \-V . Print version information to the standard output and exit. . .SH FILES . .TP .I @sysconfdir@/nsca\-ng.cfg .

The .BR send_nsca (8) client recognizes the following variables. They may appear in arbitrary order. The type of each value is denoted after an equals sign in angle brackets. . .TP \fBdelay\fP\ =\ <\fIinteger\fP> . Wait for a random number of seconds between 0 and the specified delay before contacting the server. This might be useful to reduce the server load if many .BR send_nsca (8) clients are invoked simultaneously. The default setting is 0, which tells .BR send_nsca (8) to connect to the server immediately. The specified value will be ignored if .BR send_nsca (8) is called with the .B \-D option. . .TP \fBencryption_method\fP\ =\ <\fIstring\fP> . This setting is ignored. It is accepted for compatibility with .SM NSCA 2.x. . .TP \fBidentity\fP\ =\ <\fIstring\fP> . Send the specified client identity to the server. The client identity is used for authentication and authorization. The same identity may be provided by multiple clients. By default, the local host name will be used. . .TP \fBpassword\fP\ =\ <\fIstring\fP> . Use the specified passphrase for authentication and encryption. The default password is \(lqchange-me\(rq. Change it! . .TP \fBport\fP\ =\ <\fIstring\fP> . Connect to the specified service name or port number on the server instead of using the default port (5668). The specified value will be ignored if .BR send_nsca (8) is called with the .B \-p option. . .TP \fBserver\fP\ =\ <\fIstring\fP> . Connect and talk to the specified server address or host name. The default server is \(lqlocalhost\(rq. The specified value will be ignored if .BR send_nsca (8) is called with the .B \-H option. . .TP \fBtimeout\fP\ =\ <\fIinteger\fP> . Close the connection if the server didn't respond for the specified number of seconds. If the timeout is set to 0, .BR send_nsca (8) won't enforce connection timeouts. The default timeout is 15 seconds. The specified value will be ignored if .BR send_nsca (8) is called with the .B \-o option. . .TP \fBtls_ciphers\fP\ =\ <\fIstring\fP> . Limit the cipher suites offered during the .SM TLS negotiation to the specified list of ciphers. The format of the string is described in the .BR ciphers (1) manual.

The .B send_nsca utility transmits one or more check results or monitoring commands to an .BR nsca\-ng (8) server. The communication with the server is .SM TLS encrypted and authenticated using pre-shared keys (as per .SM RFC 4279). By default, .B send_nsca reads host or service check results from the standard input. Multiple check results must be separated with an .SM ASCII ETB character (octal value: 27). Service check results are expected to be in the following format: . .PP .IR host [tab] service [tab] status [tab] message [newline] . .PP where .I host and .I service are the host name and service description as configured in Nagios, .I status is the numeric return code, and .I message is the output string. Host check results are expected to be in the same format, just without the .I service description: . .PP .IR host [tab] status [tab] message [newline] . .PP Note that multiline .IR message s are supported. . .SH OPTIONS . .TP .B \-C . Instead of accepting host or service check results in the format described above, read \(lqraw\(rq monitoring commands for submission to the Nagios command file from the standard input, one command per line. The commands are expected to be in the format described in the Nagios documentation; except that the leading bracketed timestamp may be omitted, in which case the current timestamp is prepended to the provided command by .BR send_nsca . . .TP .BI \-c\ file . Read the configuration from the specified .I file instead of using the default configuration file .IR @sysconfdir@/send_nsca.cfg . . .TP .BI \-D\ delay . Wait for a random number of seconds between 0 and the specified .I delay before contacting the server. This might be useful to reduce the server load if many .B send_nsca clients are invoked simultaneously. The default setting is 0, which tells .B send_nsca to connect to the server immediately. If this option is specified, the .B delay setting in the .BR send_nsca.cfg (5) file is ignored. . .TP .BI \-d\ delimiter . Use the specified .I delimiter instead of a horizontal tab to separate the fields when parsing host or service check results. The .I delimiter must be a single character, a C-style backslash escape sequence, the octal value of a character with a leading zero, or the hexadecimal value of a character prefixed with \(lq0x\(rq. Any .SM ASCII character other than a backslash, newline, .SM ETB, or .SM NUL is allowed. This option is ignored if the .B \-C option is specified. . .TP .BI \-e\ separator . Use the specified .I separator instead of an .SM ASCII ETB character to separate multiple host or service check results. The .I separator must be a single character, a C-style backslash escape sequence, the octal value of a character with a leading zero, or the hexadecimal value of a character prefixed with \(lq0x\(rq. Any .SM ASCII character is allowed, but note that multiline check result messages cannot be submitted if a newline character is used. This option is ignored if the .B \-C option is specified. . .TP .BI \-H\ server . Connect and talk to the specified .I server address or host name. By default, .B send_nsca attempts to communicate with \(lqlocalhost\(rq. This option takes precedence over the .B server setting in the .BR send_nsca.cfg (5) file. . .TP .B \-h . Print usage information to the standard output and exit. . .TP .BI \-o\ timeout . Close the connection if the server didn't respond for the specified number of seconds. If the .I timeout is set to 0, .B send_nsca won't enforce connection timeouts. The default .I timeout is 15 seconds. This option is provided for compatibility with .SM NSCA 2.x. If it's specified, the .B timeout setting in the .BR send_nsca.cfg (5) file is ignored. . .TP .BI \-p\ port . Connect to the specified service name or .I port number instead of using the default .I port (5668). This option takes precedence over the .B port setting in the .BR send_nsca.cfg (5) file. . .TP .B \-S . Write all messages to the standard error output. This is the default behaviour. . .TP .B \-s . Send all messages (except for usage errors) to the system logger. This option may be combined with the .B \-S option. . .TP .B \-t . This option is ignored. It is accepted for compatibility with .SM NSCA 2.x. . .TP .B \-V . Print version information to the standard output and exit. . .TP .B \-v . Generate a message for each check result or monitoring command sent to the .BR nsca\-ng (8) server. This option can be specified up to three times in order to increase the verbosity. . .SH "EXIT STATUS" . The .B send_nsca utility exits 0 on success, and >0 if an error occurs. . .SH FILES . .TP .I @sysconfdir@/send_nsca.cfg .

It is derived from the Python module written by Alexander Golovko but with a more perlish interface and additional functionality for sending arbitrary external commands. =head2 EXPORT Nothing by default. The standard Nagios return codes C, C, C, C and C are available. If you don't use something like L that exports the same values, use C<:rcodes> as above to import them. The C<:all> tag is currently synonymous with C<:rcodes> but might export more things in te future. =head1 METHODS =head2 new $o = new($host, $identity, $psk, %tags); $o = new("icinga.local", "ID", "s3cr3t", node_name => hostname()); The constructor takes three mandatory positional arguments and a number of optional ones that may be passed as hash-style arguments inline or as a hashref. The mandatory ones: =over 4 =item C<$host>: The host name or IP address of the NSCA-ng server =item C<$identity>: An arbitrary identity string that is used by the server to find the corrent PSK. You can think of this as the "user name" part of a regular login. =item C<$psk>: A pre-shared key configured on the server for C<$identity>. =back The following tags are optional: =over 4 =item C: the TCP port the NSCA-ng server runs on. Defaults to 5668. =item C: A list of ciphers for OpenSSL to use. See ciphers(1) for details and don't mess with this unless you know what you're doing. The default is fine. =item C: The name of the local host as configured in your monitoring system. This is almost always the host name. You may pass this as an argument to any of the result methods, but considering that a single host or service check hardly ever submits results for more than one host, it makes sense to specify this at construction time and not to worry about it later. =item C: The service description as configured in your monitoring system. Same rationale as C above. =item C: The timeout in seconds to wait for server responses and connection setup. Default is 10. =back The constructor dies with an error message if anything should go wrong, so use C, L or the like. =cut sub new { my ($class, $host, $identity, $psk) = splice(@_, 0, 4); my %args = @_%2 ? %{$_[0]} : @_; $class->_new($host, $args{port} // 5668, $identity, $psk, @args{qw/ ciphers node_name svc_description /}, $args{timeout} // 10, ); } =head2 svc_result svc_result($return_code, $plugin_output, %tags); svc_result(WARNING, "Warning: foo is purple!"); Submit a service check result. C<$return_code> is a Nagios-style plugin return code between 0 and 4, and C<$plugin_output> is a human-readable description. The optional arguments may be passed hash-style inline or as a hashref just like for the constructor. The supported keys are C and C, see L for their use. If specified here, the values override anything that may have been set in the constructor. If you haven't set them in the constructor, you MUST set them here though! Errors are signaled by dying with an error message. =cut sub svc_result { my ($self, $return_code, $plugin_output) = splice(@_, 0, 3); my %args = @_%2 ? %{$_[0]} : @_; my $err = $self->_result(0, @args{qw/ node_name svc_description /}, $return_code, $plugin_output ); $err and croak("svc_result: $err"); } =head2 host_result host_result($return_code, $plugin_output, %tags); host_result(OK, "Everything is peachy"); Submit a host check result. This is the same as L, the only exception being that the C argument obviously makes no sense for a host check and is thus not supported. If an C should have been set in the constructor, it is ignored for this call. =cut sub host_result { my ($self, $return_code, $plugin_output) = splice(@_, 0, 3); my %args = @_%2 ? %{$_[0]} : @_; my $err = $self->_result(1, $args{node_name}, '', $return_code, $plugin_output); $err and croak("host_result: $err"); } =head2 command command($cmd); command( sprintf("SCHEDULE_HOST_DOWNTIME;myserver;%d;%d;1;0;0;root;Hooray for NSCA-ng!", 0+time, 3600+time ) ); Submit an arbitrary command to your monitoring host. Commands have to be prefixed by a timestamp in seconds since the Unix epoch enclosed in angle brackets to be accepted by the server; if you leave this off, the method will add it for you. Refer to the Nagios/Icinga documentiation for available commands and the format to follow for each command. =cut 1; __END__ =head1 BUGS This module is not thread safe! Due do a workaround for the godawful OpenSSL API, static data has to be used, and this I cause problems with threads. The original Python library uses pthreads to get around that but due to Perl's different threading model this would probably not work. Using the C macros is a possibility but frankly I'm too lazy to try just for supporting Perl threads that don't work well in the first place. =head1 SEE ALSO L =head1 AUTHOR Matthias Bethke, Ematthias@towiski.deE =head1 COPYRIGHT AND LICENSE Copyright (C) 2015 by Matthias Bethke.

This requires a working diff program to be installed on your system. =head2 --copy=I If this option is given, a copy of each file will be saved with the given suffix that contains the suggested changes. This does not require any external programs. Note that this does not automagically add a dot between the original filename and the suffix. If you want the dot, you have to include it in the option argument. If neither C<--patch> or C<--copy> are given, the default is to simply print the diffs for each file. This requires either C or a C program to be installed. =head2 --diff=I Manually set the diff program and options to use. The default is to use C, when installed, and output unified context diffs. =head2 --compat-version=I Tell F to check for compatibility with the given Perl version. The default is to check for compatibility with Perl version 5.003_07. You can use this option to reduce the output of F if you intend to be backward compatible only down to a certain Perl version. =head2 --cplusplus Usually, F will detect C++ style comments and replace them with C style comments for portability reasons. Using this option instructs F to leave C++ comments untouched. =head2 --quiet Be quiet. Don't print anything except fatal errors. =head2 --nodiag Don't output any diagnostic messages. Only portability alerts will be printed. =head2 --nohints Don't output any hints. Hints often contain useful portability notes. Warnings will still be displayed. =head2 --nochanges Don't suggest any changes. Only give diagnostic output and hints unless these are also deactivated. =head2 --nofilter Don't filter the list of input files. By default, files not looking like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped. =head2 --strip Strip all script and documentation functionality from F. This reduces the size of F dramatically and may be useful if you want to include F in smaller modules without increasing their distribution size too much. The stripped F will have a C<--unstrip> option that allows you to undo the stripping, but only if an appropriate C module is installed. =head2 --list-provided Lists the API elements for which compatibility is provided by F. Also lists if it must be explicitly requested, if it has dependencies, and if there are hints or warnings for it. =head2 --list-unsupported Lists the API elements that are known not to be FULLY supported by F, and below which version of Perl they probably won't be available or work. By FULLY, we mean that support isn't provided all the way back to the first version of Perl that F supports at all. =head2 --api-info=I Show portability information for elements matching I. If I is surrounded by slashes, it is interpreted as a regular expression. Normally, only API elements are shown, but if there are no matching API elements but there are some other matching elements, those are shown. This allows you to conveniently find when functions internal to the core implementation were added; only people working on the core are likely to find this last part useful. =head1 DESCRIPTION In order for a Perl extension (XS) module to be as portable as possible across differing versions of Perl itself, certain steps need to be taken. =over 4 =item * Including this header is the first major one. This alone will give you access to a large part of the Perl API that hasn't been available in earlier Perl releases. Use perl ppport.h --list-provided to see which API elements are provided by ppport.h. =item * You should avoid using deprecated parts of the API. For example, using global Perl variables without the C prefix is deprecated. Also, some API functions used to have a C prefix. Using this form is also deprecated. You can safely use the supported API, as F will provide wrappers for older Perl versions. =item * Although the purpose of F is to keep you from having to concern yourself with what version you are running under, there may arise instances where you have to do so. These macros, the same ones as in base Perl, are available to you in all versions, and are what you should use: =over 4 =item C(major, minor, patch)> Returns whether or not the perl currently being compiled has the specified relationship I to the perl given by the parameters. I is one of C, C, C, C, C, C. For example, #if PERL_VERSION_GT(5,24,2) code that will only be compiled on perls after v5.24.2 #else fallback code #endif Note that this is usable in making compile-time decisions You may use the special value '*' for the final number to mean ALL possible values for it. Thus, #if PERL_VERSION_EQ(5,31,'*') means all perls in the 5.31 series. And #if PERL_VERSION_NE(5,24,'*') means all perls EXCEPT 5.24 ones. And #if PERL_VERSION_LE(5,9,'*') is effectively #if PERL_VERSION_LT(5,10,0) =back =item * If you use one of a few functions or variables that were not present in earlier versions of Perl, and that can't be provided using a macro, you have to explicitly request support for these functions by adding one or more C<#define>s in your source code before the inclusion of F. These functions or variables will be marked C in the list shown by C<--list-provided>. Depending on whether you module has a single or multiple files that use such functions or variables, you want either C or global variants. For a C function or variable (used only in a single source file), use: #define NEED_function #define NEED_variable For a global function or variable (used in multiple source files), use: #define NEED_function_GLOBAL #define NEED_variable_GLOBAL Note that you mustn't have more than one global request for the same function or variable in your project.

See the next section for details. =head1 EXAMPLES To verify whether F is needed for your module, whether you should make any changes to your code, and whether any special defines should be used, F can be run as a Perl script to check your source code. Simply say: perl ppport.h The result will usually be a list of patches suggesting changes that should at least be acceptable, if not necessarily the most efficient solution, or a fix for all possible problems. If you know that your XS module uses features only available in newer Perl releases, if you're aware that it uses C++ comments, and if you want all suggestions as a single patch file, you could use something like this: perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff If you only want your code to be scanned without any suggestions for changes, use: perl ppport.h --nochanges You can specify a different C program or options, using the C<--diff> option: perl ppport.h --diff='diff -C 10' This would output context diffs with 10 lines of context. If you want to create patched copies of your files instead, use: perl ppport.h --copy=.new To display portability information for the C function, use: perl ppport.h --api-info=newSVpvn Since the argument to C<--api-info> can be a regular expression, you can use perl ppport.h --api-info=/_nomg$/ to display portability information for all C<_nomg> functions or perl ppport.h --api-info=/./ to display information for all known API elements. =head1 BUGS Some of the suggested edits and/or generated patches may not compile as-is without tweaking manually. This is generally due to the need for an extra parameter to be added to the call to prevent buffer overflow. If this version of F is causing failure during the compilation of this module, please check if newer versions of either this module or C are available on CPAN before sending a bug report. If F was generated using the latest version of C and is causing failure of this module, please file a bug report at L Please include the following information: =over 4 =item 1. The complete output from running "perl -V" =item 2. This file. =item 3. The name and version of the module you were trying to build. =item 4. A full log of the build that failed. =item 5. Any other information that you think could be relevant. =back For the latest version of this code, please get the C module from CPAN. =head1 COPYRIGHT Version 3.x, Copyright (c) 2004-2013, Marcus Holland-Moritz.

In the following thread, David * Schwartz says that one could get around this requirement by setting some * (seemingly unrelated) OpenSSL options: * * http://thread.gmane.org/gmane.comp.encryption.openssl.devel/12242 * * However, even if this were true for the current OpenSSL code, we'll rather * not rely on the behaviour until the documentation is updated. * * - We set the SSL_MODE_ENABLE_PARTIAL_WRITE option because SSL_write() splits * up the data into 16 kB chunks, so sending larger pieces of data would * result in multiple trips around the event loop, as the first SSL_write() * attempt(s) would always be rejected with SSL_ERROR_WANT_WRITE. * * - An application must not wait for I/O readiness of the underlying socket * unless an OpenSSL call explicitly returned SSL_ERROR_WANT_READ or * SSL_ERROR_WANT_WRITE. Therefore, we kick off new SSL I/O requests via * ev_feed_event() instead of having libev wait for actual socket readiness * before calling the OpenSSL functions. * * - As an SSL_read() call invalidates the current state of the SSL_write() * stream and vice versa (i.e., there's only a single state of an SSL * connection), such a call has to be followed by a check whether the `ev_io' * watcher for the opposite I/O direction is currently active. If so, we use * ev_feed_event() to feed the event that watcher is waiting for into the * event loop (we check the `events' member of the `ev_io' struct to find out * whether it's EV_READ or EV_WRITE). This forces an SSL_read()/SSL_write() * call, which updates the state of that stream. * * For additional explanations, see the relevant OpenSSL man pages and the * following thread: * * http://thread.gmane.org/gmane.comp.encryption.openssl.devel/15766 * * An alternative approach would be to use a BIO_s_mem() layer instead of * letting OpenSSL handle the socket I/O itself. This is what the Perl module * AnyEvent::Handle does, as explained here: * * http://lists.schmorp.de/pipermail/libev/2008q2/000325.html * http://funcptr.net/2012/04/08/openssl-as-a-filter-(or-non-blocking-openssl)/ */ #if HAVE_CONFIG_H # include #endif #include #if HAVE_SYS_SOCKET_H # include #endif #ifdef HAVE_NETINET_IN_H # include #endif #if HAVE_ARPA_INET_H # include #endif #include #include #include #include #include #include #include #include #include #include #include "log.h" #include "system.h" #include "tls.h" #include "wrappers.h" #if !HAVE_STRUCT_SOCKADDR_STORAGE # if HAVE_STRUCT_SOCKADDR_IN6 # define sockaddr_storage sockaddr_in6 # else # define sockaddr_storage sockaddr_in # endif #endif #ifndef INET6_ADDRSTRLEN # define INET6_ADDRSTRLEN 46 #endif #define LINE_MAX_SIZE 2048 #define LINE_BUFFER_SIZE 128 #define LINE_TERMINATOR "\r\n" enum { READ_LINE, /* The read() function relies on READ_LINE == 0. */ READ_BYTES };
