hobbitd_channel - Feed a hobbitd channel to a worker module
hobbitd_channel --channel=CHANNEL [options] workerprogram [worker-
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.
hobbitd_channel accepts a few options.
Specifies the channel to receive messages from, only one channel
can be used. This option is required. The following channels
"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
hobbitd_channel is normally started by hobbitlaunch(8) as a task
defined in the hobbitlaunch.cfg(5) file. If you are not using
hobbitlaunch, then starting hobbitd_channel with this option
causes it to run as a stand-alone background task.
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.
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.
Redirect output to this log-file.
Enable debugging output.
This program does not use any configuration files.
