poll period missed assign yellow

I have been trying to google as well as searching the mailing list on how to do this and I am having trouble finding a suitable answer short of writing my own ping script.

I have a bunch of gear that my clients have access to and reboot/work on. It is getting to the point where alerts are going off all day long due to these "false positives." I have tried to configure wait times in hobbit-alerts.cfg however, different machines and different OSes boot at different speeds.

I would like to be able to have it so that when a piece of gear misses a poll, it goes yellow if it misses three then go red.

Thanks so much for the help.
