Monitor Alarms for External Database Systems
You can view the number of open alarms for your External Database System components.
The alarms in the Oracle Cloud Infrastructure Monitoring
service monitor External Database System components such as Oracle Databases and
listeners by using metrics and notify you when these metrics meet alarm-specified
triggers. To monitor the alarms for these components in Database Management, the OCID of the component, for example, the ASM instance, must be
specified using the resourceId dimension.
This topic provides information on how to monitor the alarms raised for External Database System components, other than databases. For information on how to monitor alarms for the databases in an External Database System, see Monitor Alarms for Managed Databases.
For information on:
- Permissions required to create alarms and how to create alarms, see Managing Alarms.
- Namespace, resources, and dimensions of the components monitored by Database Management, see Database Management Metrics for External Database Systems.
The open alarms for an External Database System and its components for which
the resourceId dimension is specified are displayed on the following
Database Management pages:
- Database System details: Displays the total number of open alarms for all the components in the External Database System.
- External cluster details: Displays the total number of open alarms for the cluster.
- External ASM details: Displays the total number of open alarms for ASM.
- External listener details: Displays the total number of open alarms for the listener.
Click the number of alarms on the Database Management pages to access the Alarms panel.
In the Alarms panel, you can:
- View the list of open alarms along with information such as the name
and severity of the alarm.
If you want to view all the open alarms in the compartment, then click the link in the introductory text in the Alarms panel. A list of open alarms is listed on the Alarm Status page in the Monitoring service.
- Select the Show suppressed alarms check box to view suppressed alarms. Suppression is a configuration to avoid publishing messages during the specified time range. For information on the suppression configuration, see Managing Alarms.
- Use the Severity drop-down list or the Search by... field to filter the list of alarms.
- Click the name of the component in the Resource name column to go to the details page of the component that has the open alarm. Note that the Resource name column is only displayed if you access the Alarms panel from the Database System details page.
- Click the name of the alarm to go to the Alarm Definitions page in the Monitoring service. On this page, you can review information about the alarm, such as its summary, severity, evaluation, and history. You can also perform tasks such as suppressing, updating, or deleting the alarm. For information on the Alarm Definitions page, see Managing Alarms.
