# 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

The ECS instance is running properly.

- 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.
