Viewing Instance Monitoring Metrics

Scenarios

Cloud Eye monitors status of your instances. You can view the monitoring metrics of instances on the management console. With these metrics, you can identify periods of high resource usage. You can also check error logs or slow query logs to optimize database performance.

Prerequisites

• Instances are running properly.

  Monitoring metrics of the instances that are faulty or have been deleted cannot be displayed on the Cloud Eye console, but you can view them after the instances are rebooted or restored to be available.

If an 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 instance.

• Instances have kept running properly for about 10 minutes.

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

Viewing Monitoring Metrics of Nodes

1. Log in to the management console.
2. Under Management & Deployment, click Cloud Eye.
3. In the navigation pane on the left, choose Cloud Service Monitoring > GaussDB(for MySQL).
4. Click in the front of the instance. Locate a node and click View Metric in the Operation column.

   You can also perform the following operations to switch to the Cloud Eye console:

   • On the Instances page, click the instance name to go to the Basic Information page. In the upper right corner of the page, click View Metric to go to the Cloud Eye console and view monitoring metrics.
   • In the Node List area of the Basic Information page, locate the primary node or a read replica and click View Metric in the Operation column to go to the Cloud Eye console and view the monitoring metrics.

5. Click Select Metric in the upper right corner. In the displayed dialog box, select the metrics to be displayed and sort them by dragging them at desired locations.

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

Viewing Real-Time Instance Monitoring Metrics

1. Log in to the management console.
2. Click in the upper left corner and select a region and a project.
3. Click in the upper left corner of the page, choose Database > GaussDB(for MySQL).
4. On the Instances page, click the instance name to go to the Basic Information page.
5. In the navigation pane on the left, choose Advanced O&M.
6. Under Real-Time Monitoring, view real-time monitoring data such as CPU usage, memory usage, SELECT statements per second, DELETE statements per second, and INSERT statements per second.
