Configure message keys to spread SNMP object identifiers

By default, most SNMP trap events are processed by a single Event Management processing job. This can negatively effect event processing. Configure message keys on the MID Server to ensure that more than one processing job is invoked, ensuring optimal SNMP trap performance.

7. To set conditions in a script that determine the message key to be used based on the SNMP traps received:
   1. Navigate to MID Server > Script Includes.
   2. Locate and select SNMPTrapKeyFilter.
   3. In the Script field, set conditions for which OIDs are to be used based on the SNMP trap event received.
   4. Select the Active check box to activate the script.
