Re: Availability of routers & interfaces
Pinging objects will give reachability.
But don't confuse this with Availability which is the real status of the device
being monitored and not the Management Station's view of what it thinks the
To get proper Availability, you need to use MIB-II variables such as sysUpTime,
ifLastChange, ifOperStatus and ifAdminStatus with calculations around them.
This will require some coding of some sort, i.e. not a straight snmpCollect
Just wanted to clarify this :)
