##  $Revision: 1.3 $
##  innwatch.ctl -- control file for innwatch.
##  Indicates what to run to test the state of the news system, and what
##  to do about it.  Format:
##	!state!when!command!test!limit!command!reason/comment
##  where
##	<!>		Delimiter; pick from [,:@;?!]
##	<state>		State to enter if true.
##	<when>		States we must be in to match.
##	<command>	Command to run to test condition.
##	<test>		Operator to use in test(1) command.
##	<limit>		Value to test against.
##	<command>	Command for innwatch to perform; use exit,
##			flush, go, pause, shutdown, skip, or throttle.
##	<reason>	Used in ctlinnd command (if needed).

##  First, just exit innwatch if innd has gone away.
##  =()<!!! test -f @<_PATH_SERVERPID>@ && echo 0 || echo 1 ! eq ! 1 ! exit ! innd dead>()=
!!! test -f /var/spool/news/data/innd/innd.pid && echo 0 || echo 1 ! eq ! 1 ! exit ! innd dead

##  Next test the load average.  Above first threshold pause, above higher
##  threshold throttle, below restart limit undo whatever was done.

##  If load is OK, check space (and inodes) on various filesystems
