HOBBITD_SAMPLE(8) System Manager's Manual HOBBITD_SAMPLE(8)NAME
hobbitd_sample - example of a hobbitd worker module
SYNOPSIS
hobbitd_channel --channel=status hobbitd_sample [options]
DESCRIPTION
hobbitd_sample is a worker module for hobbitd, and as such it is normally run via the hobbitd_channel(8) program. It receives messages from
hobbitd via stdin, and simply displays these on stdout. It can be used with all types of hobbitd channels.
hobbitd_sample is not designed to actually run, except as a demonstration. The purpose of this tool is to show how hobbitd worker modules
can be implemented to handle different tasks that need to hook into the hobbitd processing.
OPTIONS --timeout=N
Read messages with a timeout of N seconds.
--debug
Enable debugging output.

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.
FILES
This program does not use any configuration files.
