title: How to enable Visual Studio 2015 Diagnostic Tools "Showing events for:" category and threads filter
body: <p>I recently installed Visual Studio 2015 and noticed a Diagnostic Tools window I've not seen in previous versions. This window captures events, memory usage, and CPU usage. (I've been using MSDN Pro and was upgraded to enterprise.)</p>
  
  <p>I specifically wanted to try out the events section, and started up an existing website to see that part in action. Indeed many many events were recorded, both on the events timeline and the events list. However, the section titled "Showing events for:" was disabled - I had no way to filter the massive number of events being displayed.</p>
  
  <p>I did some searches on google and found lots of information about the Diagnostic Tools but didn't see anything that said that section should be disabled. Later I tried a clean web app (standard MVC, no auth template) and the section was still disabled when running the app. Next I tried a standard c# console application - with just a Console.ReadLine(); command. When I ran this I WAS able to use the "Showing events for" section. I figured it was only for web apps this piece was disabled. </p>
  
  <p>Today I asked a coworker to create a console app similar to my test described above. He ran the app and to my surprise he was unable to use the section called "Showing events for" as it was disabled. -Inconsistent behavior between my machine and his.</p>
  
  <p>Is there a simple setting I am missing that is disabling filtering on events? Just stressing again, events ARE recording and being placed on the timeline. It's just the filter section that is disabled.</p>
  
  <p>Is anyone else having a similar issue?</p>
  
  <p>Update - the filter section is also disabled during design time (not running the app) In that case all the events are removed as well.</p>
  
  <p>Update - I just tried a WPF app. I created the new application with c# and immediately ran it. Events are recorded and placed on the event timeline but the event filter is disabled.</p>
