Ubuntu Manpage: nsca-ng - monitoring command acceptor

NAME

       nsca-ng - monitoring command acceptor

SYNOPSIS

       nsca-ng [-FSs] [-b listen] [-C file] [-c file] [-l level] [-P file]

       nsca-ng -h | -V

DESCRIPTION

       The  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 TLS encrypted and
       authenticated using pre-shared keys (as per RFC 4279).  The nsca-ng server  supports  per-
       client passwords and fine-grained authorization control.

       The  server  process  rereads  its  configuration  file  when  it receives a hangup signal
       (SIGHUP) by executing itself with the name and arguments it was started with.

OPTIONS

-b listen
Bind to the specified listen address or host name. The default setting is “*”,
which tells nsca-ng to listen on all available interfaces. A colon (“:”) followed
by a service name or port number may be appended in order to override the default
port (5668) used by nsca-ng. If this option is specified, the listen setting in
the nsca-ng.cfg(5) file is ignored.

-C file
Submit monitoring commands into the specified file. This should be the named pipe
(FIFO) that Nagios checks for external commands to process. By default, nsca-ng
submits commands into /var/nagios/rw/nagios.cmd. This option takes precedence over
the command_file setting in the nsca-ng.cfg(5) file.

-c file
Read the configuration from the specified file instead of using the default
configuration file /etc/nsca-ng.cfg. If a directory is specified instead of a
file, the configuration will be read from all files with a .cfg or .conf extension
in this directory and all subdirectories. Symbolic links are followed.

-F Don't detach from the controlling terminal, and write all messages to the standard
error output (unless the -s option is specified).

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

-l level
Use the specified log level, which must be an integer value between 0 and 5
inclusive. A value of 0 tells 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 level is 3. If this option is specified, the log_level
setting in the nsca-ng.cfg(5) file is ignored.

-P file
During startup, try to create and lock the specified file and write the process ID
of the nsca-ng daemon into it. Bail out if another process holds a lock on the
file. By default, no such PID file is written. This option takes precedence over
the pid_file setting in the nsca-ng.cfg(5) file.

-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 -F option.

-s Send all messages to the system logger, except for startup messages. This is the
default behaviour (unless the -F option is specified).

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

FILES
