the main goal of the use case here is to get an alarm, if an application hangs.
In my test case I have got an application that I have monitored for some days now via an WMI process sensor. So I have data within the channels "prozessor usage", "number of handles" and so on.
The application always does something and never sleeps so that over a period of time (measured in 60 sec intervals) I could see that "processor usage" is between 0 and 12 percent and it is not longer than 2 intervals in a chain at 0 percent.
When the application hangs, the processor usage stays at 0 percent for more than 2 intervals.
So I decided to put an lower error limit on the "processor usage" channel of 1 percent and on the sensor level I configured, that after 2 errors the sensor should go in "Alarm" state.
But as you know, this does not work because the PRTG help says, errors of a channel always switch the sensor immediate into error state.
So has anyone an idea how to solve my problem, to get an error after 2 following intervals processor usage an 0 percent?
