Allow monitors to go over the usage limit during peak periods

I have a prerender service running on a DO droplet. Every two days (on average), the CPU usage peaks up to 100%, which isn't that bad, as long as it decreases within the next couple of minutes. Only once, the CPU usage was at a constant 100%, for which I had to restart the droplet / do some maintenance.

It would be nice if we could do one of the following:

Set a monitor to send a notification only if the limit has been reached for x minutes
Have monitors send a second notification when the usage is back under the limit

That way, I don't have to sign in again to check if everything is running smoothly again.
