EventReporter Event ID 11136: SNMP Monitor service: SNMP operation raised an unknown exception#

Answer#

SNMP Monitor service: SNMP operation raised an unknown exception. The product recorded this while processing snmp monitor service; the appended event detail identifies the affected object, operation, or provider error.

Event details#

  • Event ID: 11136

  • Severity: Error

  • Component: SNMP Monitor service

  • Windows Event Log source: Adiscon EvntSLog

  • Available since: 26.07

  • Message pattern: SNMP Monitor service: SNMP operation raised an unknown exception. Additional detail: {event_detail}

Possible causes#

  • Sender and receiver transport, port, SNMP version, security or community, OID, or value type do not match.

  • The receiver is not bound, a firewall drops the traffic, or the SNMP library returned the appended runtime error.

Immediate checks#

  1. Record transport, endpoint, SNMP version, security or community, OIDs, and the complete runtime detail.

  2. Confirm the intended receiver process owns the configured endpoint and accepts a paced test trap.

  3. Verify the received OID and value before changing filters or MIB settings.

Detailed procedures#

Verify the result#

Repeat or monitor the affected operation and confirm that Event ID 11136 does not recur and that snmp monitor service processing continues.

Evidence to collect#

  • The complete Windows Application Event Log entry, including all event detail.

  • The product name, exact version, service account, and event timestamp with time zone.

  • A configuration export and debug log covering the same time window, with secrets removed.
