问题
I have an ASP.Net MVC 4 application hosted on Windows Server 2008. I'm using Microsoft Application Insights, and it's working perfectly for client side metrics such as Client Processing Time, Custom Events, Users, Sessions, Page Views, etc. However, I cannot get any server-side metrics such as Processor Time or Available Memory. The areas are all covered by a banner that says something to the effect of "Learn how to collect server request data". When I click on the banner, it shows a blade with instructions, all of which I've already completed (the quick start).
In addition to installing the Application Insights SDK through VS 2013 (0.12.0-build17386), I've also installed and configured the Application Insights Status Monitor on the server. I've restarted IIS, and even restarted the server. Despite all this, I cannot get any server metrics. I've read the troubleshooting guide, and I've checked everything mentioned therein such as making sure the app pool identity is part of the "Performance Monitor Users" group.
I feel as though there is something I have to do to the ApplicationInsights.config file in order to either turn on and / or define the server metrics I want, but I simply cannot find any documentation on this.
Any help or suggestions would be greatly appreciated. Thanks!

No you shouldn't do anything additional with ApplicationInsights.config. Performance counters are the part of default monitoring package and almost all problems are related to that user is not the part of 'Performance Monitor Users' group, but it's not your case.
To be sure that config is correct you can check that the following module is defined in ApplicationInsights.config:
<Add Type="Microsoft.ApplicationInsights.Extensibility.PerfCollector.PerformanceCollectorModule, Microsoft.ApplicationInsights.Extensibility.PerfCollector"/>
Also do you see any notifications in the StatusMonitor and/or traces/exceptions in the Diagnostic search at the application insights resource overview blade?

Ok, we've got it. There was an ApplicationInsights.config in the root folder of the application, and that was the only one I've ever looked at. At Yulia Safarova's suggestion, I discovered another one inside the bin folder. This one did NOT have the module definition specified. (It was basically empty). I copied all the contents of the one from the root into the one in the bin folder, and all the data started to flow.

If you are looking for the server data like CPU, Memory, Response rate to be displayed on the Azure Application Insight, then along with the addition of above module, also make sure that the web application Identity user is part of the administrator group on the server. and below flag is turned on in web.config
"EnableAppInsightUsageCollection" value="true"
