Monitoring External Devices Using SNMP

It is often critical for an administrator to receive alerts from applications that are not managed by Enterprise Manager. Many of these applications can be configured to trigger SNMP traps when an alert condition takes place. You can receive these traps within Enterprise Manager and start monitoring those applications from Enterprise Manager. Having the capability to receive and analyze SNMP traps raised by such applications allows you extend Enterprise Manager's monitoring and alerting capabilities to these applications and reduce monitoring complexity in your IT environments.

You can configure Enterprise Manager to receive the SNMP traps raised by an application (not managed by Enterprise Manager) and display the traps as alerts in Enterprise Manager.

To receive these traps, you must develop a metadata plug-in to represent the managed entity. Then use an SNMP receivelet or SNMP fetchlet to receive or get monitoring data about that entity.

For more information about developing metadata plug-ins, see the Oracle Enterprise Manager Cloud Control Extensibility Programmer's Reference.
