Create an alert definition that will be disabled when triggered.
Create a recovery alert definition with the following duration trigger: When conditions are met for 2 minutes within a period of 2 minutes.
Set both alert definitions to have their conditions met each minute.
Wait for the primary alert definition to trigger. The alert will appear on the Alerts page.
Wait for the recovery alert definition to trigger. The alert will appear on the Alerts page with the same Alert Date as the primary alert. The recovery alert should have an Alert Date at least 2 minutes later.
NOTE: This problem may happen for counter triggers as well. We need to check. Also, this problem has been reported in the forums as confusing to users.
