The SNMP Trap Monitor receives SNMP Traps and Informs sent by networked devices. You configure those devices to forward Traps to PA Server Monitor, and configure the device trap thresholds, etc. So really, the SNMP Trap Monitor is an SNMP Trap receiver.
By default, all received traps will be alerted on. You can optionally create a filter that will only fire actions on specific traps that are received. Select the Set Filter button to enter your filter either using text or Regular Expression.
If you want to send some traps to one group of people, and other traps to a separate group, create two or more separate SNMP Trap monitors to watch for each group's specific traps.
If you will be forwarding traps via an E-mail Action, you can optionally specify that each individual trap be sent as a separate email.
MIB files are not required to receive traps, but they usually make traps more human-readable. You can add MIBs to the system by copying them into the following folder on the Central Monitoring Service:
C:\Program Files\PA Server Monitor\MIBs
Every few minutes, MIBs copied to that folder will get loaded and parsed, and shared among Consoles or Satellites that don't have them.
Near the bottom of the dialog, you'll see this area where common SNMP removal text is shown:
Removal text is shared among all SNMP monitors and Actions. Any time an SNMP object is reported on, the removal text is removed from the SNMP object's name. This helps cut down on clutter and makes reading the SNMP object names much easier.
Like all monitors, this monitor has standard buttons on the right for Adding Actions and setting Advanced Options. This monitor does not have a Schedule button since a schedule is not needed to receive traps.
