I've been playing around with some of the alerts, but didn't find this option. I would like an alert to be generated if NPM cannot successfully poll a device IP after two polling intervals with X amount of failed retries with each interval.
I was also wondering for devices like access switches, if the switchports can be monitored, but not indicate an event everytime the switchport goes down? I'd still like it monitored though for useage/errors stuff like that
