Viewing alert records

After an alert of a cloud service instance is triggered, an alert record is automatically generated. The alert record records information such as the name of the faulty resource, the time when the alert is triggered, the duration of the alert, the alert level, and the name of the alert policy, which facilitates your viewing and reviewing the alert record in a centralized manner.

Limits

An alert record can be stored for up to 14 days.

If the number of alert records exceeds 5,000, only the latest 5,000 alert records are displayed.

An alert record covers the period from the time when an alert of a resource instance is triggered for the first time to the time when the alert is cleared. If the alert is triggered again after clearance, another alert record will be generated.

Viewing alert records

In the left navigation bar, click Alert Center > Alert History.

You can filter for the target alert record by specifying a time period and filter conditions above the alert record list.

The following table describes the meaning of each column in the alert record list.
