I'm creating alerts and currently I have them set to alert if an app component is not in Up status. The problem is when we first assign templates they immediately alert us because they are "Unknown" since they are being polled for the first time. But I don't really want to filter out Unknown from the alerting since I would think that status could come up other times when there actually are issues. How can I filter out so that if the initial poll is still in progress, it won't alert? I can't find any fields that would allow this in creating the alert.
