innwatch - monitor innd.
innwatch [ -l logfile ] [ -t seconds ]
Innwatch is normally started by rc.news. It periodically -- every
<config$INNWATCH_SLEEPTIME> (typically 600 ) seconds -- examines the load
average, and the number of free blocks and inodes on the spool partition,
as described by its control file, innwatch.ctl(5).
If the load gets too high, or the disk gets too full, it throttles the
server. When the condition restores, it unblocks the server. In
addition, on each pass through the loop it will check the logfile
<config$_PATH_MOST_LOGS>/news.crit (typically /var/log/news/news.crit )
to see if it has been modified, and send mail to the news administrator
Upon receipt of an interrupt signal (SIGINT), innwatch will report its
status in the file <config$_PATH_INNWSTATUS> (typically
-l To specify a log file to watch, other than the default of news.crit,
use the ``-l'' flag.
-t To change the period between check from the default, use the ``-t''
