innwatch - Monitor the state of INN and the system
innwatch [-f ctlfile] [-i seconds] [-l
logfile] [-t seconds]
innwatch is normally started and stopped by rc.news when
doinnwatch is set to true in inn.conf. Every
innwatchsleeptime seconds, as set in inn.conf as well as other
parameters tuning its behaviour, innwatch examines the load average,
and the number of free blocks and inodes on the spool partition, as described
by its control file, innwatch.ctl in pathetc.
If the load gets too high, or the disk gets too full, it throttles
the server. When the condition restores, it unblocks the server. In
addition, on each pass through the loop, it will check the logfile
pathlog/news.crit to see if it has been modified, and send mail to
the news administrator if so.
Upon receipt of an interrupt signal (SIGINT), innwatch will
report its status in the file innwatch.status in pathrun.
- -f file
- Specify the control file to use, other than the default of
innwatch.ctl in pathetc.
- -i seconds
- With this option, innwatch has an initial sleep of seconds
seconds at startup. This is useful when innwatch is started at the
same time as INN, so that it can wait a little before beginning performing
its checks.
- -l logfile
- Specify a log file to watch, other than the default of
news.crit.
- -t seconds
- Specify the period in seconds between checks, to override the value set in
inn.conf.
