Hi community,
Recently we have found strange behavior of IIS performance counters "Current Anonymous Users" and "Current NonAnonymous Users". Both of them are showing maximum allowed value (4 billion +) after first anonymous/non-anonymous requests respectively.
The Login web site is using Thincktecture.IdentityServer3 and the Ids3Default web site is their example of how to use IdentityServer3 with MVC application. The third (hidden) application is just a client which uses Login web site as identity server. As you can see for third one counters are working as expected.
I have already created issue on thinktecture bug tracker (https://github.com/IdentityServer/IdentityServer3/issues/1881), but I would like to know what can affect IIS Performance counters in general.
It is worth to mention, actual performance is NOT affected.
