HOBBITD_CHANNEL(8)					      System Manager's Manual						HOBBITD_CHANNEL(8)

NAME

       hobbitd_channel - Feed a hobbitd channel to a worker module

SYNOPSIS

       hobbitd_channel --channel=CHANNEL [options] workerprogram [worker-options]

DESCRIPTION

       hobbitd_channel	hooks  into  one  of  the  hobbitd(8)  channels  that  provide information about events occurring in the Xymon system.	It
       retrieves messages from the hobbitd daemon, and passes them on to the workerprogram on the STDIN (file descripter 1) of the worker program.
       Worker programs can then handle messages as they like.

       A number of worker programs are shipped with hobbitd, e.g.  hobbitd_filestore(8) hobbitd_history(8) hobbitd_alert(8) hobbitd_rrd(8)

       If you want to write your own worker module, a sample worker module is provided as part of the hobbitd distribution in the hobbitd_sample.c
       file. This illustrates how to easily fetch and parse messages.

OPTIONS

       hobbitd_channel accepts a few options.

       --channel=CHANNELNAME
	      Specifies the channel to receive messages from, only one channel can be used.  This option is required. The following  channels  are
	      available:
	      "status" receives all Xymon status- and summary-messages
	      "stachg" receives information about status changes
	      "page" receives information about statuses triggering alerts
	      "data" receives all Xymon "data" messages
	      "notes" receives all Xymon "notes" messages
	      "enadis" receives information about hosts being disabled or enabled.

       --daemon
	      hobbitd_channel  is normally started by hobbitlaunch(8) as a task defined in the hobbitlaunch.cfg(5) file. If you are not using hob-
	      bitlaunch, then starting hobbitd_channel with this option causes it to run as a stand-alone background task.

       --pidfile=FILENAME
	      If running as a stand-alone daemon, hobbitd_channel will save the proces-ID of the daemon in FILENAME. This is useful for  automated
	      startup- and shutdown- scripts.

       --env=FILENAME
	      Loads  the  environment variables defined in FILENAME before starting hobbitd_channel.  This is normally used only when running as a
	      stand-alone daemon; if hobbitd_channel is started by hobbitlaunch, then the environment is controlled by the task definition in  the
	      hobbitlaunch.cfg(5) file.

       --log=FILENAME
	      Redirect output to this log-file.

       --debug
	      Enable debugging output.
