NAME

       xymonlaunch - Master program to launch other Xymon programs

SYNOPSIS

       xymonlaunch [options]

DESCRIPTION

       xymonlaunch(8)  is  the  main program that controls the execution and scheduling of all of
       the components in the Xymon system.

       xymonlaunch  allows  the  administrator  to  add,  remove  or  change  the  set  of  Xymon
       applications  and  extensions  without  restarting  Xymon - xymonlaunch will automatically
       notice any changes  in  the  set  of  tasks,  and  change  the  scheduling  of  activities
       accordingly.

       xymonlaunch also allows the administrator to setup specific logfiles for each component of
       the Xymon system, instead of getting output from all components logged to a single file.

OPTIONS

       --env=FILENAME
              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
              tasks.cfg(5)

       --config=FILENAME
              This option defines the file that xymonlaunch scans for tasks  it  must  launch.  A
              description of this file is in tasks.cfg(5) The default tasklist is /etc/tasks.cfg

       --log=FILENAME
              Defines  the  logfile  where  xymonlaunch logs information about failures to launch
              tasks and other data about the operation of xymonlaunch. Logs from individual tasks
              are defined in the tasks.cfg file. By default this is logged to stdout.

       --pidfile=FILENAME
              Filename  which xymonlaunch saves its own process-ID to. Commonly used by automated
              start/stop scripts.

       --verbose
              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 tasks.cfg file after parsing it.  Used for debugging.

       --debug
              Enable debugging output while running.

       --no-daemon
              xymonlaunch  normally  detaches  from  the controlling tty and runs as a background
              task. This option keeps it running in the foreground.

STARTING TASKS

       xymonlaunch 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  xymonlaunch  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 xymonlaunch logfile.

       If the configuration file changes, xymonlaunch 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.
