Why Are ECS Instances Displayed in the Monitoring Diagram Different from Those Displayed in the Table on the Basic Information Page of an AS Group?

Abnormal are replaced during health check. When the AS group is disabled, the health status of ECSs will still be checked, but abnormal ECSs state will not be replaced. Therefore, the quantity of ECS instances displayed on the AS group monitoring page is different from the actual quantity in the AS group.


Issue 2:


The monitoring diagram on the Basic Information page records the quantity of available ECSs in the AS group, which is reported by AS to CES periodically, while the table provides scaling action logs of the AS group. AS may fail to report the data to CES due to network failure or other causes. This may affect correctness of data on the diagram.




Handling Method


Issue 1:



  1. Go to the Instance tab page and check for ECSs whose health status is Abnormal in the instance list.

  2. Enable the AS group again. Abnormal ECSs will be replaced during health check, and the quantity of ECS instances displayed on the AS group monitoring page will be the same as the actual instance.


Issue 2:




  1. Use the data in the table when the data in the monitoring diagram is inconsistent with that in the table or some details are missing on the diagram, because scaling action logs provided in the table record instance changes before and after each scaling action.

  2. Contact the administrator for handling.
