Monitoring the System Using Oracle Enterprise Manager Cloud Control

1.4 Monitoring the System Using Oracle Enterprise Manager Cloud Control

Oracle Exadata Database Machine can be monitored by Oracle Enterprise Manager Cloud Control agents using the Oracle Exadata Plug-in and the Oracle Systems Infrastructure Plug-in. The Oracle Exadata Database Machine is discovered and monitored as a system target in Oracle Enterprise Manager Cloud Control. Individual database servers, storage servers, and switches are grouped together under the system target for the Oracle Exadata Database Machine so they can be monitored as a group

The Oracle Exadata Storage Server metrics are collected and managed by Management Server (MS). When used with Oracle Enterprise Manager Cloud Control, the metrics are presented as Oracle Enterprise Manager Cloud Control metrics.

All Exadata server alerts are delivered to Oracle Enterprise Manager Cloud Control using SNMP. The Exadata hardware and software components are monitored by Integrated Lights Out Manager (ILOM) and Oracle Exadata System Software in the following ways:

Hardware components are monitored by ILOM. When a hardware component reports a failure or an exceeded threshold, ILOM reports the failure as an SNMP trap to MS. MS processes the trap, creates an alert, and delivers the alert to the Oracle Enterprise Manager Cloud Control agent.
Hardware and software components are also monitored by MS directly. When a failure or threshold is exceeded, MS processes the trap, creates an alert, and delivers the alert to the Oracle Enterprise Manager Cloud Control agent.

From the end-user perspective, there is no difference between the two types of alerts. The alert message contains the corrective action to resolve the alert.
