What is a Trap Mask?

Alarms transition from one state to another when NerveCenter fires a trigger. There are four different types of trigger generators:

• A poll
• A trap mask
• Another alarm
• A Perl subroutine

Trap masks screen SNMP traps. These traps may be sent by managed nodes or by other sources, such as a NerveCenter server.

A trap mask is similar to a poll in its ability to trigger one or more alarms. Whereas a poll actively monitors conditions, the mask passively waits until it receives a relevant SNMP trap to act.

The Role of a Trap Mask within a Behavior Model

You, the user, define the complexity of the trigger each mask fires.
