Version 1.6                                      March 19, 2019                                     send_nsca(8)

Description

       The send_nsca utility transmits one or more check results or monitoring commands to an nsca-ng(8) server.
       The  communication  with  the server is TLS encrypted and authenticated using pre-shared keys (as per RFC
       4279).  By default, send_nsca reads host or service check results  from  the  standard  input.   Multiple
       check results must be separated with an ASCII ETB character (octal value: 27).  Service check results are
       expected to be in the following format:

            host[tab]service[tab]status[tab]message[newline]

       where  host  and service are the host name and service description as configured in Nagios, status is the
       numeric return code, and message is the output string.  Host check results are expected to be in the same
       format, just without the service description:

            host[tab]status[tab]message[newline]

       Note that multiline messages are supported.

Exit Status

       The send_nsca utility exits 0 on success, and >0 if an error occurs.

Name

send_nsca - send monitoring commands to NSCA-ng server

Options

-C Instead of accepting host or service check results in the format described above, read “raw”
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 send_nsca.

-cfile
Read the configuration from the specified file instead of using the default configuration file
/etc/send_nsca.cfg.

-Ddelay
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 send_nsca clients are invoked
simultaneously. The default setting is 0, which tells send_nsca to connect to the server
immediately. If this option is specified, the delay setting in the send_nsca.cfg(5) file is
ignored.

-ddelimiter
Use the specified delimiter instead of a horizontal tab to separate the fields when parsing host
or service check results. The 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 “0x”. Any ASCII character other than a backslash, newline, ETB, or NUL is
allowed. This option is ignored if the -C option is specified.

-eseparator
Use the specified separator instead of an ASCII ETB character to separate multiple host or service
check results. The 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 “0x”. Any 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 -C option is
specified.

-Hserver
Connect and talk to the specified server address or host name. By default, send_nsca attempts to
communicate with “localhost”. This option takes precedence over the server setting in the
send_nsca.cfg(5) file.

-h Print usage information to the standard output and exit.

-otimeout
Close the connection if the server didn't respond for the specified number of seconds. If the
timeout is set to 0, send_nsca won't enforce connection timeouts. The default timeout is 15
seconds. This option is provided for compatibility with NSCA 2.x. If it's specified, the timeout
setting in the send_nsca.cfg(5) file is ignored.

-pport
Connect to the specified service name or port number instead of using the default port (5668).
This option takes precedence over the port setting in the send_nsca.cfg(5) file.

-S Write all messages to the standard error output. This is the default behaviour.

-s Send all messages (except for usage errors) to the system logger. This option may be combined
with the -S option.

-t This option is ignored. It is accepted for compatibility with NSCA 2.x.

-V Print version information to the standard output and exit.

-v Generate a message for each check result or monitoring command sent to the nsca-ng(8) server.
This option can be specified up to three times in order to increase the verbosity.
