Querying GaussDB Monitoring Metrics

Scenarios

Cloud Eye monitors operating statuses of DB instances. You can view the DB instance monitoring metrics on the management console. For details, see Viewing Metrics of DB Instances.

Monitored data takes some time for transmission and display. The DB instance status displayed on the Cloud Eye console is the status of the last 5 to 10 minutes. If your DB instance is newly created, wait for 5 to 10 minutes and then view the monitoring data.

You can also view database metrics on the Monitoring Dashboards page of the GaussDB console. On the Monitoring Dashboards page, you can select all nodes or components of an instance at the same time to check their metrics. In this way, you can easily compare metric differences between components or nodes. In contrast, CES allows you to check metrics of only one node or component at a time.

Prerequisites

• A DB instance is running properly.

  Monitoring metrics of the DB instances that are faulty or have been deleted cannot be displayed on the Cloud Eye console. You can view their monitoring metrics after they are rebooted or restored to be normal.

If a DB instance has been faulty for 24 hours, Cloud Eye considers that it does not exist and deletes it from the monitoring object list. You need to manually clear the alarm rules created for the DB instance.

• The DB instance keeps running properly for about 10 minutes.

  For a newly created DB instance, you need to wait for a while before viewing the monitoring metrics.

Viewing Metrics of DB Instances

1. Log in to the management console.
2. Click in the upper left corner and select a region and project.
3. Under Management & Governance of the service list, click Cloud Eye.
4. In the navigation pane on the left, choose Cloud Service Monitoring > GaussDB.
5. Click the target instance name to view its monitoring information.

   Cloud Eye can monitor performance metrics in the last 1 hour, last 3 hours, last 12 hours, last 24 hours, or last 7 days.

   You can also click in the upper left corner of the page and choose Databases > GaussDB. On the Instances page, click View Metric in the Operation column of the row containing the target instance to go to the Cloud Eye console. Alternatively, click the name of the target DB instance on the Instances page. On the displayed page, click View Metric in the upper right corner to go to the Cloud Eye console.
