Integrating Munin with Mon

Munin already integrates with Nagios .. But I didn’t find anything for mon ..

So I hacked check_munin.pl from Nagios Exchange to work with mon ..

Download munin.monitor and place it in mon.d/ of your mon installation.

Now you can monitor ANY munin value using mon.

Use something like the following in your systems_monitor.m4

watch system01
    service disk_root
        interval 5m
        monitor munin.monitor -M df -F _dev_cciss_c0d0p1 -w 90 -c 95 -H
        depend SELF:ping
        period _ANYTIME_
            alertevery 15m summary
            comp_alerts
            alertafter 3
            alert mail.alert _MY_EMAIL_
            upalert mail.alert _MY_EMAIL_
    service toomanyqueuedmails
        interval 5m
        monitor munin.monitor -M sendmail_mailqueue -F mails -w 50 -c 100 -H
        depend SELF:ping
        period _ANYTIME_
            alertevery 15m summary
            comp_alerts
            alertafter 3
            alert mail.alert _MY_EMAIL_
            upalert mail.alert _MY_EMAIL_
    service dnsresponse
        interval 5m
        monitor munin.monitor -M dnsresponse_193.92.110.1 -F avg -w 20 -c 50 -H
        depend SELF:ping
        period _ANYTIME_
            alertevery 15m summary
            comp_alerts
            alertafter 3
            alert mail.alert _MY_EMAIL_
            upalert mail.alert _MY_EMAIL_

Make sure that your MON server’s IP is allowed in munin-node.conf of your munin client.
