Mini MVC profiler: appears to be displaying profile times for every static resource

Question

I've just started using the mvc-mini-profiler (http://code.google.com/p/mvc-mini-profiler/) and I think it's awesome. However, I'm getting some odd behaviour while using it.

I've got an ASP.NET Webforms site running on IIS7.5 and for some reason when I load a page with the profiler enabled, I not only get a time measurement for the aspx page, but I also get it for random css and js resources on the page.

The aspx profile works correctly, with the SQL query also being profiled correctly. However, as the picture shows I also get a bunch of other results which appear to be results for static CSS and JS files. As far as I can tell, these are being served up statically by IIS, so the profiler code shouldn't even be invoked for these.

The relevant parts of my Global.asax are:

    protected void Application_BeginRequest()     {         MiniProfiler profiler = null;          // might want to decide here (or maybe inside the action) whether you want         // to profile this request - for example, using an "IsSystemAdmin" flag against         // the user, or similar; this could also all be done in action filters, but this         // is simple and practical; just return null for most users. For our test, we'll         // profile only for local requests (seems reasonable)         profiler = MiniProfiler.Start();          using (profiler.Step("Application_BeginRequest"))         {             // you can start profiling your code immediately         }     }      protected void Application_EndRequest()     {         MvcMiniProfiler.MiniProfiler.Stop();     }      protected void Application_AuthenticateRequest(object sender, EventArgs e)     {         if (User == null || !User.Identity.IsAuthenticated)         {             MvcMiniProfiler.MiniProfiler.Stop(true);         }     } 

Is this behaviour expected?

Answer 1

Yes this is correct but it is very easy to filter these out.

Taken from the sample code in the project Source

void Application_Start(object sender, EventArgs e) {     // Code that runs on application startup      // some things should never be seen     var ignored = MiniProfiler.Settings.IgnoredPaths.ToList();      ignored.Add("WebResource.axd");     ignored.Add("/Styles/");      MiniProfiler.Settings.IgnoredPaths = ignored.ToArray(); } 

This lets you filter out what you want to see or not this is a sample of what I have excluded in my web application which i am finding is working for my application

ignored.Add("WebResource.axd"); ignored.Add("ScriptResource.axd"); ignored.Add("/Styles/"); ignored.Add("/Images/"); ignored.Add(".js");

You can actually put that in one line and also omit the slashes. Like this:

    protected void Application_BeginRequest()     {         if (Request.IsLocal)         {             MiniProfiler.Start();             MiniProfiler.Settings.IgnoredPaths = new[] { "static", "webresource.axd", "styles", "images" };         }      }
