Hi,
I'm troubleshooting hardware alert related problem.
I have created APM Hardware Sensor rule which monitors sensor status - outruling Up and Unknown status.

I just found out that there have been problems on hardware and I can see them on events view:

Problem is that alert rule has not worked - only alert that has been worked by rule is that last one on 23:15 when "Front Panel Board 1 Altitude" has changed to Up.
I'm wondering what property monitor I should use to catch up such hardware errors?
