Evaluating and Clearing Entity Alerts from Oracle Management Cloud

Introduction

In this article, we will see how to view outstanding warning/critical/fatal alerts and we will clear the alerts which were not in an active state with step by step navigation and instructions.

Evaluating and Clearing Alerts

After adding targets to the OMC, initially, it is very much expected to receive warning/critical/fatal alerts from the target(s). These alerts may be old which were scanned from the diag files. Hence, we will review and clear the alerts for the targets. Target(s) can be the database or Host level or ASM etc. Same time it is not a good practice to clear them without review. We need to investigate each of the alerts and need to ensure the warnings were not active or recent. After determining the alerts, if they are not active, we will see how to clear them safely.

Connect to the OMC console (Management Cloud → Monitoring)

OMC Dashboard, Navigation to Monitoring

In the below screen we can see fatal, critical and warning alerts and they were outstanding. The reason for the outstanding maybe it could be an ongoing issue or its historical issue. In our example, we have two critical alerts and click on them.

Enterprise Summary of Entity

In the first critical alert, the message is very clear — Oracle database was brought down(shutdown/abort) and we can also see the last updated and the duration or life of this alert. If these targets were not added to the blackout, then we will receive such alerts directly and hence in case of any downtime we need to put the targets into the blackout.

Warnings to be cleared

The second alert more related to ASM and related to SCAN — we can also see one more hint in the message as “ internal” — In such cases better to crosscheck if any known bugs after proper review of DIAG logs at the server level. This alert basically pointing out to a bug and this issue is fixed in Agent 1.33.

Oracle Management Cloud :FetchletException: Result has repeating key value (Doc ID 2478679.1)

Next, we can add some comment and click on the clear button as it’s known issue as per the bug number.

Put the comment and then clear

After clearing the message, we can see the status as the alert is cleared.

Status of the cleared alert

Here in our case both alerts are known cases. If there are unknown cases, we have to put efforts to identify the root cause.

Likewise, we can also view such alerts directly from “OMC → Management Cloud → Alerts” and this page will show the alerts very meaningful with picture overview as below.

Summary

In this article, we have seen how to review the alerts of the entities and how to troubleshoot the alerts with two examples and finally, we have cleared the alerts for the known issues.
