I've created a sensor based on the "Event Log (Windows API) sensor" which checks every 6 hours the application log for specific ids. Now I would be notified when such id is found in the last 6 hours. Therefore I configured the "New records" with limitations (I tried it with 6 decimal places and an upper error limit of 0.000001) - but this won't work as expected, mostly the sensor measures 0.000000 #/s. To get not lost in try and error: What's the best way to measure such event records? What's the best mix of scanning interval and error limits?
