I’ve several pairs of Cisco PIX failover clusters, till now I’ve never really monitored their status because I do not have snmp-trap servers but today I discovered one pair did a failover due to a cable problem a while ago so I figured it’s time I do something about it.
I’ve written a quick guide on using Nagios, Net-SNMP and a few MIBs from Cisco to monitor it and to alert you if any change in the status of your failover clusters happen.
