I use a small script (found in this Mail
List and a little modified by me) to check some daemons.
You can add some other daemon, if you need...
-> in crontab:
*/2 * * * * /usr/sbin/check_daemons.sh >> /var/log/check_daemons.log
-> # cat /usr/sbin/check_daemons.sh
#! /bin/sh
perl /usr/sbin/check_daemons.pl >> /var/log/check_daemons.log
echo "--------------------- done -------------------" >>
/var/log/check_daemons.log
tail -n 500 /var/log/check_daemons.log > /var/log/check_daemons.log.tmp
rm /var/log/check_daemons.log
mv /var/log/check_daemons.log.tmp /var/log/check_daemons.log
exit 0
-> # cat /usr/sbin/check_daemons.pl
#!/usr/bin/perl
# ========================================================================
# File : check_daemons.pl
# Purpose : Runs from cron.
