Also we like to monitor frame utilization on the cambiums. However since Libre 
(and Cambium far as I know) have not supported individual utilization per beam 
on the Medusas I take them out. 

Here is an alert for that. 

wireless_sensors.sensor_descr REGEXP "Downlink" AND 
wireless_sensors.sensor_class = "utilization" AND 
wireless_sensors.sensor_current > 90 AND devices.sysName NOT LIKE '%medusa%' 

This will tell us any AP that has frame utilization over 90% over the course of 
a certain period of time before it triggers. 

A basic notification if an AP loses sync and has none or is generating its own 

sensors.sensor_current = 2 AND sensors.sensor_type = 
"WHISP-APS-MIB::whispGPSStats" AND sensors.sensor_prev = 1

Sam, 
Most of that is done in the rules for what you want to detect as up or down 
ICMP or SNMP 
Mine sends me texts and does a weekly report on performance I select to report 
on. 
Love it :)

Is there anyone out there that could point me in the right direction to get 
alerting set up correctly? I have tried a few times to get AP's to alert me 
when they fail, but Libre seems to have some random ways to determine whether a 
device is up or down.
