Hi all,

stopped
stopped(7) Miscellaneous Information Manual stopped(7)NAME
stopped - event signalling that a job has stopped
SYNOPSIS
stopped JOB=JOB INSTANCE=INSTANCE RESULT=RESULT [PROCESS=PROCESS] [EXIT_STATUS=STATUS] [EXIT_SIGNAL=SIGNAL] [ENV]...
DESCRIPTION
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
limit.
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.
EXAMPLE
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
