We monitor about 3000 routers with ping only. We ping an RFC 1918 IP assigned to the loopback interface on the router. That way, as long as any serial interface on the router is up, the router is still 'up' without us having to configure every a ping for every serial interface. This is sufficiently 'up' for our SLA purposes... For the purposes of parenting, the ping check is likely sufficient. We also monitor the individual interfaces via SNMP to know when any one goes down. We have a process such that we don't need to add each specific serial interface into nagios but just figure what should be up in real time. -- Marc ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
