We are just about to purchase a 500-sensor license for PRTG and would be very interested to be able to send Soap requests and interogate the response from a web service.
I have found a couple of threads in the KB that mention this isn't yet possible, but many of these are quite old threads, and at one point the functionality was stated as "being on the wishlist". Is it still on the wishlist?
One thing I've noticed is that the XML restrictions on the HTTP Advanced Sensor appear to have been lifted - can I now use this sensor to POST SoapAction requests to my web services and create sensor output based on the response? All of the settings in the sensor configuration page appear to support this, but I have not been able to get it working so far (if it is possible, I can provide more information on what I have attempted so far).
The other option of course is to write a custom Powershell or EXE sensor but I'd like to use out-of-the box functionality wherever possible to maintain low cost and low maintenance.
Any information on this topic would be greatly appreciated
