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 by using Instance Details page

  1. Log on to the ECS console.
  2. In the left-side navigation pane, click Instances. Select a region.
  3. Click an instance to go to the Instance Details page.
  4. On the Instance Details  page, you can view the monitoring information, including CPU utilization 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 run the top command in the command line. 
    • Then, pressShift+P key to list programs by CPU utilization to view which processes are using the most CPU resources.
    • For Windows instances,  use the Task Manager on an instance to  view the CPU utilization 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.
