I’m using SVN version 5742 and all of my alerts work except those that are supposed to check a sensor_value metric. I’m able to check and get emails for alerts on processor_usage, toner_current, and mempool_perc, to name a few, so I know the system is working.

When I run the alerter.php script against one of the hosts indicated under the processor_usage alert and I get “1 Status: OK” messages. But when I run alerter.php against a host indicated under the sensor_value alert for Battery Capacity or for APC UPS Temperature I get “-1 Unknown status”. The graphs for these sensors are fine, the MySQL table sensors-state lists the correct values as well.

My configuration for temperature looks like this:

Entity Type: Temperature

Delay: 1

Status: 0/0/0/0/2

Check Conditions: Require any condition

Tests: sensor_value gt 40

Device Match: type match power

Entity Match: sensor_descr match Temp*

The alert checker seems fine, but it looks like the tests are failing when they are run.

Has anyone else had the same issues with sensor_value alerts? Or is this feature not quite ready to be used?
