hobbitlaunch - Master program to launch other Hobbit programs
hobbitlaunch(8) is the main program that controls the execution and
scheduling of all of the components in the Hobbit system.
hobbitlaunch allows the administrator to add, remove or change the set
of Hobbit applications and extensions without restarting Hobbit -
hobbitlaunch will automatically notice any changes in the set of tasks,
and change the scheduling of activities accordingly.
hobbitlaunch also allows the administrator to setup specific logfiles
for each component of the Hobbit system, instead of getting output from
all components logged to a single file.
Loads the environment from FILENAME before starting other tools.
The environment defined by FILENAME is the default, it can be
overridden by the ENVFILE option in hobbitlaunch.cfg(5)
This option defines the file that hobbitlaunch scans for tasks
it must launch. A description of this file is in
hobbitlaunch.cfg(5) The default tasklist is
Defines the logfile where hobbitlaunch logs information about
failures to launch tasks and other data about the operation of
hobbitlaunch. Logs from individual tasks are defined in the
hobbitlaunch.cfg file. By default this is logged to stdout.
Filename which hobbitlaunch saves its own process-ID to.
Commonly used by automated start/stop scripts.
Logs the launch of all tasks to the logfile. Note that the
logfile may become quite large if you enable this.
--dump Just dump the contents of the hobbitlaunch.cfg file after
parsing it. Used for debugging.
Enable debugging output while running.
hobbitlaunch normally detaches from the controlling tty and runs
as a background task. This option keeps it running in the
hobbitlaunch will read the configuration file and start all of the
tasks listed there.
If a task completes abnormally (i.e. terminated by a signal or with a
non-zero exit status), then hobbitlaunch will attempt to restart it 5
times. If it still will not run, then the task is disabled for 10
minutes. This will be logged to the hobbitlaunch logfile.
If the configuration file changes, hobbitlaunch will re-read it and
notice any changes. If a running task was removed from the
configuration, then the task is stopped. If a new task was added, it
will be started. If the command used for a task changed, or it was
given a new environment definition file, or the logfile was changed,
then the task is stopped and restarted with the new definition.
