Most network devices now-a-days are capable of sending
out SNMP traps when a fault occurs.
A good fault monitoring system should be able to support SNMP
traps and provide meaningful information to the operators.
OpManager does exactly that by providing support for basic
SNMP traps out-of-the-box.
Operators can also add support for traps from any custom SNMP
MIB. OpManager can extract useful information that is sent
with SNMP traps as variable bindings. (SNMP varbinds)
So if you have bought devices from different vendors,
all you need to do is get access to those vendor-specific
MIBS and you can easily have OpManager monitoring
critical variables on that device.
