Sorting is a way to arrange alerts in ascending or descending order according to some attribute of the alerts. By default, alerts are sorted descending by server time so that the most recent alerts appear at the top of the alerts pane.
To reorder alerts
Click the heading of the column on which you want to sort the alerts. Click the column heading a second time to switch from ascending to descending or vice versa.
Tip: Sort alerts so that the information you need is available at a glance.
