How does the IIS sensor gather its data?



I am trying to identify where a spike in IIS traffic reported by PRTG is coming from. I do not see any web log activity or application log activity during the time when PRTG reports a 1000x increase in activity. Where does this sensor gather its data on GET, POST, File Sent/Received, Not Found Errors, etc??

Hi there,

The IIS sensors gather their information via performance counters. You can open the perfmon on the target device and check the values manually.

Best regards, Felix
