innwatch - Man Page

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.
