SNMP alerts overview

Send Simple Network Management Protocol (SNMP) traps to an enterprise monitoring system such as those provided by Nagios. SNMP is a standardized framework for infrastructure monitoring. Organizations use SNMP to monitor the status of their network infrastructure.

OpsCenter supports SNMP traps, not full SNMP agent, for integration with an agentless monitoring solution. The OpsCenter SNMP implementation supports sending traps over SNMPv1, SNMPv2c, and SNMPv3 protocols. The device being monitored is opscenterd, the OpsCenter daemon. Traps send an alert from a monitored device (opscenterd) to the SNMP master (such as a Nagios application). OpsCenter supports SNMP as an event plugin, similar to the email and post URL alert plugins. SNMP requires import of an MIB.

OpsCenter MIB fields

The OpsCenter MIB is SMIv2-compliant. The fields identified in the trap when using the OpsCenter MIB (Management Information Base) include those standard to all alerts, with the exception of an additional time field.
