View historical alert information
The Historical Alerts page provides information about all alerts that were triggered during the selected time period. Information at the top of the page includes how many of these alerts have been triggered over time, the number of alerts with each status, and the entities that most frequently trigger the alerts. Below those widgets, a table lists all alerts triggered during the time period.

In the left pane, click Alerts > Historical Alerts.

To change the information shown, you can change the time period, apply filters, sort the table, or search:
