Answer

The latest MTTrapd probe is required for the SNMP_WATCH unknown engineid feature.
Release ID: 22.3.0 or higher.
The include rules file logic is required for the engineid reset.
include "$NCHOME/omnibus/probes/linux2x86/mttrapd.bidir.rules"
include "$NCHOME/omnibus/probes/linux2x86/mttrapd.snmpwatch.rules"
The probe property file requires the command line interface to be enabled, and EngineInfoProbeWatch enabled.

The aggregation object must have access to the MTTrapd probes command line port.
A file containing the steps required to test the SNMP_WATCH automation SNMPv3 engineid features is provided, along with a tar file of the configuration files and test scripts.
The canned traps and test scripts are provided by two related FAQs.
  • Checking SNMP trap reception for the MTTrapd probe
  • Using the command-line interface to manage the MTTrapd probes SNMPv3 engine
Comment
The mttrapd_triggers trigger group is disabled by default.
To enable the trigger group run the following SQL.
alter trigger group mttrapd_triggers set enabled true;
go
