The Alert History tab displays history for all alerts and the
incident log. In the Alert History tab, you can:
View a list of all alerts and incident log entries, or use the
Date filter drop-down list to view a subset of alerts and
entries, such as those that occurred in the last 24 or 48 hours or
during a custom set of dates.
View alerts based on their severity, such as informational,
warning, or error.
After selecting an individual alert, change the status,
severity, or owner of that alert. (To do this, right-click or
double-click the alert and choose the desired setting.)
