Reply To: Alert not firing

I would suggest changing the Comparing line in the alert.  Change it to greater than > and the number of seconds you want to check for.

Example:  > 3600  means has not received in 60 minutes (60×60).

Your duration should be fine.  It just means that the condition must hold true for the specified period of time.

Only other thing I can caution you on for LastR alerts is if you are resetting stats in the night or whenever (hcimsiutil -Z), that clears the alert ‘memory’ of when the last message actually was received, and can cause false alerts on threads that don’t see steady flow.  To get around this sort of thing, set the time window appropriately.  Example – if you want an alert to trigger if you haven’t received in 2 hours, and you reset your stats at 1am, set the alert window to start at 3am.  It should alert right at 3am if nothing is received.  But if you don’t have this time window, you could potentially see false alerts around 1am when stats are reset.
