Why might I not be getting any results from MiniProfiler?

Question

I can't seem to get any results from MiniProfiler.

I can see the XHR POST to /mini-profiler-resources/results returning a 404. The chrome request inspector gives me a standard server 404 page.

A GET on the same URL also returns a 404, but there is a message saying that "no results were found for the specified id" (I did add the id in the querystring).

When I look at /mini-profiler-resources/results-index it just gives me an empty table with the field headings in - name, started, sql, duration, etc.

I've tried a few things - details below - at this stage I am at a loss as to what I can try next. Any pointers or suggestions for debugging this problem would be much appreciated.

Installed Packages:

• MiniProfiler (v3.2.0.157)
• MiniProfiler.EF6 (v3.0.11)
• MiniProfiler.MVC4 (v3.0.11)

Where MVC4 also caters for MVC5. Which this project is.

---

Relevant Code:

    protected void Application_Start()
    {
        MiniProfilerEF6.Initialize();
        MiniProfiler.Settings.Results_List_Authorize = IsUserAllowedToSeeMiniProfilerUI;
        MiniProfiler.Settings.MaxJsonResponseSize = int.MaxValue;
        Database.SetInitializer<ApplicationDbContext>(null);
        GlobalFilters.Filters.Add(new ProfilingActionFilter());
        var copy = ViewEngines.Engines.ToList();
        ViewEngines.Engines.Clear();
        foreach (var item in copy)
        {
            ViewEngines.Engines.Add(new ProfilingViewEngine(item));
        }
    }


    protected void Application_BeginRequest(Object source, EventArgs e)
    {
        if (Request.IsLocal)
        {
            // this IS being hit
            MiniProfiler.Start();
        }
    }


    protected void Applicaton_EndRequest()
    {
        MiniProfiler.Stop(discardResults: false);
    }


    private bool IsUserAllowedToSeeMiniProfilerUI(HttpRequest httpRequest)
    {
        return true;
    }

In HomeController.cs:

[AllowAnonymous]
public ActionResult Index()
{
    var profiler = MiniProfiler.Current;
    using (profiler.Step("Doing complex stuff"))
    {
        using (profiler.Step("Step A"))
        {
            ViewBag.Title = "Home Page";
        }
        using (profiler.Step("Step B"))
        { 
            Thread.Sleep(250);
        }
    }

    return View();
}

And in MasterLayout.cshtml:

@using StackExchange.Profiling; 

... 

@MiniProfiler.RenderIncludes()

I've Tried:

I have set discardResults to false, like this:

    protected void Applicaton_EndRequest()
    {
        MiniProfiler.Stop(discardResults: false);
    }

---

I can confirm that MiniProfiler.Start() IS getting hit when the page loads.

---

I can also confirm that the mini-profiler-resources/ route IS being found (using Haack's Route Debugger)

---

I have the following item in the <handlers> section of web.config, and it is in the correct section (e.g. this guy mistakenly put it in the ELMAH config ).

  <add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />

---

I have set all my output caching to 1 second.

---

I was using a custom applicationhost.config file to test on a custom url.

I tried removing the custom url bindings and just using the standard localhost:51347.

I also tried putting the snippet below into applicationhost.config instead of the standard web.config.

<add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />

---

In applicationhost.config I tried changing

<section name="handlers" overrideModeDefault="Deny" />

to

<section name="handlers" overrideModeDefault="Allow" />

---

I've added the following into application_start:

MiniProfiler.Settings.MaxJsonResponseSize = int.MaxValue;

---

As recommended in this answer, I have tried uninstalling all related packages and reinstalling them in this order:

• MiniProfiler
• MiniProfiler.MVC4
• MiniProfiler.EF6

Update

9 days on, the bounty expired and still no joy :(

If anybody reading this in the future has ideas / suggestions, I'd really like to hear them. MiniProfiler is such a great tool and I'm disappointed that I haven't been able to get it working on this occasion.

If I do find the answer myself, I'll post it.

Answer 1

After running into the same issue I found the answer here which worked fine. http://www.mukeshkumar.net/articles/mvc/performance-test-with-miniprofiler-in-asp-net-mvc

If you get an error after running application with MiniProfiler.Mvc4 or MiniProfiler.Mvc3 which state “/mini-profiler-resources/includes.js 404 not found” then simply add the following line of code in Web.Config inside web server section.

<system.webServer>
    <handlers>
      <add name="MiniProfiler" path="mini-profiler-resources/*"
               verb="*" type="System.Web.Routing.UrlRoutingModule"
               resourceType="Unspecified" preCondition="integratedMode" />
    </handlers>   
</system.webServer>
