It sounds like the same problem I'm having with ipMonitor.
If (and only if) you have Alerting Rules set up individually for each monitor, you can go into each rule and disable "Alert Recovery Notification".
- Alert List
- Click the Alert name
- Uncheck "Send Recovery Notifications" in "Notification Content - Recovery Messages"
But this is rarely the case, since I think almost everyone opts for setting the alert rules by Group or Device instead of individually for hundreds of Monitors--and you don't want to disable Recovery Notification for everything else that uses this Alert Rule.
Now, I'm new to ipMonitor as well, so I'm not sure if this helps or not. I've been searching around, and I'm not sure if there's a better way to go about it. Hopefully an official support person can answer your question better than myself.
