I have a health check used by my loadbalancers that I'd like to track in PRTG.

the health check is a simple IIS website. The one thing I find wierd is that the file that is loaded is a .exe. for example the url is Http:server/perfagent.exe if you browse to the site it simply displays an integer from 1-100.

In my sensor I get this error: Last Message Request returned not enough values. (0/1) (code: PE174)

If I configure 'Write sensor result to disk' the sensor's logfile shows the number (and only the number) which sounds like it's working.

can anyone help?
