Asp.Net MVC Error Handling & logging

You could try elmah for error logging if that is what you are looking for.

If you were rolling your own Exception logging you could create a base Controller class that overrides the OnException method

public class BaseController : Controller
{
    protected override void OnException(ExceptionContext filterContext)
    {
        ExceptionPolicy.HandleException(filterContext.Exception, "MyPolicy");
        base.OnException(filterContext);            
    }
}

Elmah

Elmah could be great option for you. It is easy to use, after installing nuget package is ready for use.

Custom logging with log4net etc.

If you want to log errors by your own, I recommend this example app: https://github.com/mholec/mvcexceptionhandler where is explained global logging with your favorite log tool (log4net, nlog, etc.)

Application Insights

Another and maybe the best way is to use Application Insights. Application Insights you can install quickly using NuGet and you will get great overview of your application errors, website availability and you can get more information about your users. This service is free.

I recommend ELMAH http://code.google.com/p/elmah/

You can get started very quickly with it by using Nuget to set it up. http://nuget.codeplex.com/

1. Setup Nuget.
2. In vstudio -> View -> Other Windows -> Package Manager
3. List-Package -filter elmah
4. install-package elmah and you're all set.

You can view the log just like trace.axd by going to http://mysite/elmah.axd and manually throw errors to elmah like this:

try { 
}
catch (Exception ex)
{
   ErrorSignal.FromCurrentContext().Raise(ex);
}

hope that helps, -fs
