hobbitlaunch.cfg - Task definitions for the hobbitlaunch utility
The hobbitlaunch.cfg file holds the list of tasks that hobbitlaunch
runs to perform all of the tasks needed by the Xymon monitor.
A task is defined by a key, a command, and optionally also interval,
environment, and logfile.
Blank lines and lines starting with a hash mark (#) are treated as
comments and ignored. Long lines can be broken up by putting a
backslash at the end of the line and continuing the entry on the next
An entry looks like this:
The key is enclosed in angle brackets, and must be unique for each
task. You can choose your key-names as you like, they are only used
internally in hobbitlaunch to identify each task.
The command is defined by the CMD keyword. This is the full command
including any options you want to use for this task. This is required
for all tasks.
The DISABLED keyword means that this command is disabled. hobbitlaunch
will not start this task. It is recommended that you use this to
disable standard tasks, instead of removing them or commenting them
out. Upgrades to Xymon will add standard tasks back into the file, so
unless you have them listed as DISABLED then tasks may re-appear
unexpectedly after an upgrade.
The ONHOST keyword tells hobbitlaunch that this task should only run on
specific hosts. After the ONHOST keyword, you must provide a "regular
expression"; if the hostname where hobbitlaunch runs matches this
expression, then the task will run. If it doesn’t match, then the task
is treated as if it were DISABLED.
The MAXTIME keyword sets a maximum time that the task may run; if
exceeded, hobbitlaunch will kill the task. The time is in seconds by
default, you can specify minutes, hours or days by adding an "m", "h"
or "d" after the number. By default there is no upper limit on how long
a taskmay run.
The NEEDS instructs hobbitlaunch not to run this task unless the task
defined by the NEEDS keyword is already running. This is used e.g. to
delay the start of some application until the needed daemons have been
started. The task that must be running is defined by its key.
The GROUP keyword can be used to limit the number of tasks that may run
simultaneously. E.g. if you are generating multiple pagesets of
webpages, you dont want them to run at the same time. Putting them
into a GROUP will cause hobbitlaunch to delay the start of new tasks,
so that only one task will run per group. You can change the limit by
defining the group before the tasks, with a "GROUP groupname maxtasks"
The INTERVAL keyword defines how often this command is executed. The
example shows a command that runs every 5 minutes. If no interval is
given, the task is only run once - this is useful for tasks that run
continually as daemons - although if the task stops for some reason,
then hobbitlaunch will attempt to restart it. Intervals can be
specified in seconds (if you just put a number there), or in minutes
(5m), hours (2h), or days (1d).
The ENVFILE setting points to a file with definitions of environment
variables. Before running the task, hobbitlaunch will setup all of the
environment variables listed in this file. Since this is a per-task
setting, you can use the same hobbitlaunch instance to run e.g. both
the server- and client-side Xymon tasks. If this option is not present,
then the environment defined to hobbitlaunch is used.
The ENVAREA setting modifies which environment variables are loaded, by
picking up the ones that are defined for this specific "area". See
hobbitserver.cfg(5) for information about environment areas.
The LOGFILE setting defines a logfile for the task. hobbitlaunch will
start the task with stdout and stderr redirected to this file. If this
option is not present, then the output goes to the same location as the
hobbitlaunch(8), hobbitd(8), xymon(7)
