You can monitor the operating statuses of instances to ensure optimal performance.

You can monitor the status of instances using the following two portals:

  • Instance Details page
  • CloudMonitor

Monitor the status of an instance using Instance Details page

To monitor the Status of an instance using Instance Details, perform the following:

  1. Log on to the ECS console.

  2. Click Instances in the left navigation bar.

  3. Select your desired region.

  4. Click the instance you want to monitor.

  5. On the Instance Details page, you can view the monitoring information, including CPU usage and outbound/inbound network traffic information.

    • Information about CPU monitoring:
      • For Linux instances, use the top command to view CPU usage details. Log on to the instance and execute the top command in the command line. Then, pressShift+P key to list programs by CPU usage to view which processes are using the most CPU resources.
      • For Windows instances, use the Task Manager on an instance to view the CPU usage to view which programs are using the CPU resources of the server.
    • The displayed monitoring data shows the Internet traffic of the instance in Kbps (1 Mbps = 1,024 Kbps). The monitoring data shows inbound and outbound instance traffic. For 1 Mbps of bandwidth, the bandwidth is working at full capacity if the outbound network traffic reaches 1,024 Kbps.


To install a CloudMonitor, perform the following:

  1. On the Alibaba Cloud Console, select Products and Services > CloudMonitor.

  2. In the left-side navigation pane, click Host Monitoring, and then select the name of the instance you wish to monitor.

  3. Click Click to Install to monitor the instance OS. Click Monitoring Chart to view basic parameters. Click Alarm Rules to set alarm rules.
