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
