NAME

       power-status-changed - event signalling change of power status

SYNOPSIS

       power-status-changed [ENV]...

DESCRIPTION

       The  power-status-changed event is generated by the Upstart init(8) daemon when it receives the SIGPWR signal, this has been typically gen-
       erated by UPS monitoring software such as powstatd(8)

       This event is not handled in the default Upstart configuration.

EXAMPLE

       A task to be run on change of power status might use:

	      start on power-status-changed

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
