I do have my OWIN application hosted as a Windows Service and I am getting a lot of timeout issues from different clients. I have some metrics in place around the request/response time however the numbers are very different. For example I can see the client is taking around one minute to perform a request that looks like in the server is taking 3-4 seconds. I am then assuming that the number of requests that can be accepted has reached the limit and subsequent requests that come in would get queued up. Am I right? If that's the case, is there any way I can monitor the number of incoming requests at a given time and how big is the queue (as in number of requests pending to get served)?
I am playing around with https://msdn.microsoft.com/en-us/library/microsoft.owin.host.httplistener.owinhttplistener.setrequestprocessinglimits(v=vs.113).aspx but doesn't look to have any effect.
Any feedback is much appreciated.
THanks!
HttpListener is built on top of Http.Sys so you need to use its performance counters and ETW traces to get this level of information. https://msdn.microsoft.com/en-us/library/windows/desktop/cc307239%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396 http://blogs.msdn.com/b/wndp/archive/2007/01/18/event-tracing-in-http-sys-part-1-capturing-a-trace.aspx
