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.
