This topic describes how to monitor the CPU usage and CPU credits of a burstable performance instance. When an instance is running, the CPU usage changes dynamically. As a result, the CPU credits vary according to both the CPU usage and the baseline performance of the instance.

Procedure

  1. Log on to the ECS console.
  2. In the left-side navigation pane, choose Instances & Images > Instances.
  3. Find the target instance and click the instance ID.
  4. On the Instance Details page, view the monitoring information of the instance in the Monitoring Information area.

    The following table describes trend charts in the Monitoring Information area.

    Trend chart Description
    CPU Shows the trend of CPU usage.
    Burstable Instance-CPU Credit Consumption Shows the trend of CPU credit consumption. The trend corresponds to the CPU usage. For more information, see CPU credit consumption.
    Burstable Instance-CPU Credit Balance Shows the trend of CPU credit balance, that is, CPU credits that can be used to burst above the baseline performance. For more information, see Earn CPU credits.
    Burstable Instance-Overdrawn CPU Credits Shows the trend of overdrawn CPU credits. Overdrawn CPU credits can be used only when you enable the unlimited mode. For more information, see Unlimited mode.
    Burstable Instance-Advance CPU Credits Shows the trend of advance CPU credits. Advance CPU credits can be used only when you enable the unlimited mode. For more information, see Unlimited mode.
