Sounds pretty good. May I suggest tweaking the hysteresis? With the logic as described, I would expect to get an alert email every 10 minutes. It might be better to suppress alerts until a check sees that the condition has cleared. An extension might add a "low tide" reset mark some distance from the trigger level (e.g. <= 80%) to avoid small oscillations around the 90% mark. A low-frequency (i.e. daily or weekly) nag also helps keep persistent issues from being forgotten. Just trying to offer my experience if not my time. - Daniel
