Viewing Monitoring Metrics
Scenarios
The cloud platform provides Cloud Eye to help you obtain the running status of your ECS instances. This section describes how to view details of AS group metrics to obtain information about the status of the ECS instances in the AS group.
Prerequisites
- Monitoring metrics such as CPU Usage and Disks Read Rate are available only when there is at least one instance in an AS group. If not, only the Number of Instances metric is available.
- Monitoring data is not displayed for a stopped, faulty, or deleted instance. After such an instance restarts or recovers, the monitoring data is available.
Viewing Monitoring Metrics on Auto Scaling
- Log in to the management console.
- Under Compute, click Auto Scaling. In the navigation pane on the left, choose Instance Scaling. Then click the AS Groups tab.
- On the AS Groups page, find the AS group to view monitoring data and click its name.
- Click the Monitoring tab to view the monitoring data.
You can view data of the last one, three, 12, or 24 hours, or last 7 days. If you want to view data for a longer time range, click View details to go to the Cloud Eye page, hover your mouse over a graph, and click
.
Viewing Monitoring Metrics on Cloud Eye
- Log in to the management console.
- Click
in the upper left corner to select a region and a project.
- Under Management & Governance, select Cloud Eye.
- In the navigation pane on the left, choose Cloud Service Monitoring > Auto Scaling.
- Locate the row that contains the target AS group and click View Metric in the Operation column to view monitoring data.
You can view data of the last one, three, 12, or 24 hours, or last 7 days. Hover your mouse over a graph and click
to view data for a longer time range.
It can take a period of time to obtain and transfer the monitoring data. Therefore, wait for a while and then check the data.
