stopped - event signalling that a job has stopped
stopped JOB=JOB INSTANCE=INSTANCE RESULT=RESULT [PROCESS=PROCESS] [EXIT_STATUS=STATUS]
The stopped event is generated by the Upstart init(8) daemon when an instance of a job has
stopped. The JOB environment variable contains the job name, and the INSTANCE environment
variable contains the instance name which will be empty for single-instance jobs.
If the job was stopped normally, the RESULT environment variable will be ok, otherwise if
the job was stopped because it has failed it will be failed.
When the job has failed, the process that failed will be given in the PROCESS environment
variable. This may be pre-start, post-start, main, pre-stop or post-stop; it may also be
the special value respawn to indicate that the job was stopped because it hit the respawn
Finally in the case of a failed job, one of either EXIT_STATUS or EXIT_SIGNAL may be given
to indicate the cause of the stop. Either EXIT_STATUS will contain the exit status code
of the process, or EXIT_SIGNAL will contain the name of the signal that the process
received. The normal exit job configuration stanza can be used to prevent particular exit
status values or signals resulting in a failed job, see init(5) for more information.
If neither EXIT_STATUS or EXIT_SIGNAL is given for a failed process, it is because the
process failed to spawn (for example, file not found). See the system logs for the error.
init(8) emits this event as an informational signal, services and tasks started or stopped
by this event will do so in parallel with other activity. It is typically combined with
the starting(7) event by services when inserting themselves as a dependency.
Job configuration files may use the export stanza to export environment variables from
their own environment into the stopped event. See init(5) for more details.
A service that wishes to be running whenever another service would be running, started
before and stopped after it, might use:
start on starting apache
stop on stopped apache
A task that must be run after another task or service has been stopped might use:
start on stopped postgresql
starting(7) started(7) stopping(7) init(5)
