Monitor burstable instances

Query CPU credit usage information

You can perform the following steps to query the real-time credit trend of a burstable instance in the ECS console.

1. Log on to the ECS console.
2. In the left-side navigation pane, choose Instances & Images > Instances.
3. In the top navigation bar, select a region.
4. Find the burstable instance that you want to query and click the instance ID.
5. On the Instance Details page that appears, view the CPU credit usage and CPU utilization information of the instance.

Create CPU credit alert rules

1. Log on to the CloudMonitor console.
2. In the left-side navigation pane, choose Alarms > Alarm Rules.
3. On the Alarm Rules page, click Create Alarm Rule.
4. On the Create Alarm Rule page, complete the following configurations:
   1. Configure parameters in the Related Resource section.
      • Product: Select ECS from the drop-down list.
      • Resource Range: Select Instances from the drop-down list.
      • Instances: Select one or more burstable instances.
   2. Configure parameters in the Set Alarm Rules section.
      • Alarm Rule: Customize an alert rule name.
      • Rule Description: Set alert rules and judgment standards.
        • Monitoring of Total Credit: Select Total Credit to monitor banked CPU credits. The values of 1Minute cycle, Continue for 1 periods, Average, <, and 1 are used in this example. If the average value of Total Credit is less than 1 and the status lasts for at least 1 minute, an alert is triggered.
          Note In standard mode, if the banked CPU credits are less than 1, the CPU utilization of the burstable instance cannot exceed the baseline performance. In unlimited mode, if the CPU utilization exceeds the baseline performance, the burstable instance will consume advance CPU credits. If all advance CPU credits are consumed, the burstable instance will consume overdrawn CPU credits. You can also configure the average value for multiple consecutive periods as the alert triggering condition based on your actual requirements on CPU performance.
          
        • Monitoring of Notpaid Surplus Credit: Select Notpaid Surplus Credit to monitor overdrawn CPU credits. The values of 1Minute cycle, Continue for 1 periods, Average, >, and 0 are used in this example. If the average value of Notpaid Surplus Credit is greater than 0 and the status lasts for at least 1 minute, an alert is triggered.
          Note If overdrawn CPU credits are greater than 0, overdrawn CPU credits are being used and billed. You can also configure the average value for multiple consecutive periods as the alert triggering condition based on your actual requirements on billing of overdrawn CPU credits.
          
        • Monitoring of Burst Credit: Select Burst Credit to monitor consumed CPU credits.
        • Monitoring of AdvanceCredit: Select AdvanceCredit to monitor advance CPU credits.
      • Mute for: Select the interval at which notifications are pushed. The value of 10 min is used in this example.
      • Effective Period: Select the time range during which you can receive notifications.
   3. Set parameters in the Notification Method section.
      • Notification Contact: Select a contact group to receive notifications.
      • Notification Methods: Select Email + DingTalk (Info) or other methods as needed.
