[Observium] Alerts based on RRD averages?

Hi all,

I'm curious if it is possible to create an alert that considers an RRD average? For example, if I want to generate an alert that looks at the average utilization of a port over a 24 hour period, and if the average bit rate or percentage is greater than X, send an alert?

I have been working with alerts that trigger based on a percentage, but if the port drops below that mark for even a short period of time (minutes, perhaps even an hour or two), the clock resets. That's proving troublesome.

Any suggestions?

Thanks,
