How To Implement Elmah In Asp Net Mvc
instructions look at the DotNetSlackers Article. Setting up ELMAH on MVC is asp net mvc 5 error handling really simple since most of the work is done in web.config that is more or less shared between MVC and
Asp Net Mvc Error Handling Best Practices
Webforms. There are already excellent (and more detailed) articles in this Wiki on how to configure and fine tune ELMAH. This Article is intended to provide a quick and simple tutorial asp net mvc exception handling on the most important steps to get ELMAH up and running on MVC. (For advanced users seeking MVC-specific information, skip ahead to Step 4) Step 1: Referencing the assembliesFirst, grab the latest binary release of elmah from the project’s page and extract the bin folder. ELMAH requires no GAC installation, so you can drop the contents of the bin to any location of your asp net mvc handleerror liking (although I usually recommend using a lib folder to store external dependencies) and reference the Elmah.dll from within your app. Step 2: Edit your web.config to call ELMAHFirst add the following code to your
By Joe Lowrance said, er tweeted, it best when he said, "the amount of attention ELMAH hasn't got is shocking." ELMAH is one of those largely unknown and deeply awesome .NET Open Source projects that should be part of ASP.NET proper. What is
Asp Net Mvc Handler
ELMAH? I like to say that ELMAH is Tivo for your ASP.NET Errors. You can get elmah mvc your Yellow Screens of Death, with full call-stack back and analyze what's really happening. It's Exception Driven Development. What's it really do? Once
Elmah Mvc 5
ELMAH has been dropped into a running web application and configured appropriately, you get the following facilites without changing a single line of your code: Logging of nearly all unhandled exceptions. A web page to remotely view the https://code.google.com/p/elmah/wiki/MVC entire log of recoded exceptions. A web page to remotely view the full details of any one logged exception. In many cases, you can review the original yellow screen of death that ASP.NET generated for a given exception, even with customErrors mode turned off. An e-mail notification of each error at the time it occurs. An RSS feed of the last 15 errors from the log. A number of backing storage implementations for the log, including http://www.hanselman.com/blog/ELMAHErrorLoggingModulesAndHandlersForASPNETAndMVCToo.aspx in-memory, Microsoft SQL Server and several contributed by the community. Created by Atif Aziz (@raboof on Twitter) and Scott Mitchell, ELMAH means is "Error Logging Modules and Handlers" and has been rocking my world since, well, September of 2004. (Small Correction, Scott Mitchell helped writing the original MSDN article. ELMAH is 100% conceived of by Atif.) From the project site: ELMAH (Error Logging Modules and Handlers) is an application-wide error logging facility that is completely pluggable. It can be dynamically added to a running ASP.NET web application, or even all ASP.NET web applications on a machine, without any need for re-compilation or re-deployment. ELMAH is wonderful for many reasons. First, because it just works. Second, because it's a fantastic example of effective use of HttpModules and HttpHandlers working together. Third, because it's been design with enough thought that nearly anything you'd want from it for use in a production site is there. I'm sitting here in a cafe and I'm going to add ELMAH to the ASP.NET MVC-based NerdDinner.com Source Code. Actually, the site, as I don't need to recompile the source if I'm not doing anything tricky. ;) Implementing ELMAH on your ASP.NET (MVC or otherwise) Site I download ELMAH, and I put its DLL in my /bin folder (or wherever you like to put libraries). ELMAH doesn't need to be referenced by your project directly if yo

that line from our Global.asax.cs in Part 1? Well, building our own HandleErrorAttribute will allow us to put it back or more importantly prevent the HandleErrorAttribute from overriding our ELMAH behavior. Currently the HandleError attribute will prevent any errors from bubbling up to ELMAH and we can't guarantee down the line, someone won't use a HandleError attribute like this... [HandleError] public class MyClass { // This error won't be handled by ELMAH public MyMethod() { throw new Exception("oops"); } } The solution to this problemis to implement our own custom HandleErrorAttribute. Add the following class to your project... using System; using System.Web; using System.Web.Mvc; using Elmah; namespace ElmahAndMvc3 { public class ElmahHandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute { public override void OnException(ExceptionContext context) { base.OnException(context); var e = context.Exception; if (!context.ExceptionHandled // if unhandled, will be logged anyhow || RaiseErrorSignal(e) // prefer signaling, if possible || IsFiltered(context)) // filtered? return; LogException(e); } private static bool RaiseErrorSignal(Exception e) { var context = HttpContext.Current; if (context == null) return false; var signal = ErrorSignal.FromContext(context); if (signal == null) return false; signal.Raise(e, context); return true; } private static bool IsFiltered(ExceptionContext context) { var config = context.HttpContext.GetSection("elmah/errorFilter") as ErrorFilterConfiguration; if (config == null) return false; var testContext = new ErrorFilterModule.AssertionHelperContext( context.Exception, HttpContext.Current); return config.Assertion.Test(testContext); } private static void LogException(Exception e) { var context = HttpContext.Current; ErrorLog.GetDefault(context).Log(new Error(e, context)); } } } And modify the RegisterGlobalFilters in your Global.asax.cs... public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new ElmahHandleErrorAttribute()); } Now you have no worries about [HandleError] intercepting errors on your site.
