can this alert be configured so only if PLE is below a threshold and stays below the threshold for a "n" seconds, the alert needs to be fired! Most of the time PLE goes low for few seconds and comes back up immediately. I would configure for this alert to fire if PLE is less than 300 for at least 60 seconds. Can this be done ? Or can this be added for future *** ? Ideally most alerts should have a duration tied to them.
Can you add that as a feature request here: http://community.idera.com/database-management/product-documentation/i/feature-requests
It is a good idea and we have been thinking of some more generalized similar changes for alerting. So I would like to see how the community votes and comments on the idea.
In the Alert Configuration dialog there is a button "Advanced" in the lower right corner. Click on it, and you will get a new dialog, where you can specify how many minutes the threshold value has to be exceeded, before an alert is raised.
You can do this for most, if not all, metrics.
