How to: Handle Application-Level Errors Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 This code example shows how to create an error handler in the Global.asax file that will catch all unhandled ASP.NET errors while processing a request — in other words, all application_error mvc the errors that are not caught with a Try/Catch block or in a page-level error handler. In the example, the handler transfers control to a generic error page named GenericErrorPage.aspx, which interprets the error and displays an appropriate message. Example The following example is from a complete code sample in Complete Example for Error Handlers. Security Note Never set customErrors to Off in your Web.config file if you do not have an Application_Error handler in your Global.asax file. Potentially compromising information about your Web site can be exposed to anyone who can cause an error to occur on your site. C#VB Copy void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs // Get the exception object. Exception exc = Server.GetLastError(); // Handle HTTP errors if (exc.GetType() == typeof(HttpException)) { // The Complete Error Handling Example generates // some errors using URLs with "NoCatch" in them; // ignore these here to simulate what would happen // if a global.asax handler were not implemented. if (exc.Message.Contains("NoCatch") || exc.Message.Contains("maxUrlLength")) return; //Redirect HTTP errors to HttpError page Server.Transfer("HttpErrorPage.aspx"); } // For other kinds of errors give the user some information // but stay on the default page Response.Write("

takes a minute: Sign up How do you log errors (Exceptions) in your ASP.NET apps? up vote 21 down vote favorite 12 I'm looking for the best way to log errors in an ASP.NET application. I want to be able to https://msdn.microsoft.com/en-us/library/24395wz3.aspx receive emails when errors occurs in my application, with detailed information about the Exception and the current Request. In my company we used to have our own ErrorMailer, catching everything in the Global.asax Application_Error. It was "Ok" but not very flexible nor configurable. We swithed recently to NLog. It's much more configurable, we can define different targets for the errors, filter them, buffer them (not tried yet). It's a very good improvement. But I discovered lately that there's a whole Namespace http://stackoverflow.com/questions/11950/how-do-you-log-errors-exceptions-in-your-asp-net-apps in the .Net framework for this purpose : System.Web.Management and it can be configured in the healthMonitoring section of web.config. Have you ever worked with .Net health monitoring? What is your solution for error logging? Thanks, Vincent asp.net error-handling nlog health-monitoring share|improve this question edited Jan 23 '09 at 9:45 edosoft 9,6772063103 asked Aug 15 '08 at 4:05 Costo 2,84762235 I've also seen System.Web.Management, but I've never used it. I'd love to hear any feedback on whether it works well. –Ben Mills Dec 4 '08 at 22:00 add a comment| 8 Answers 8 active oldest votes up vote 25 down vote accepted I use elmah. It has some really nice features and here is a CodeProject article on it. I think the StackOverflow team uses elmah also! share|improve this answer answered Aug 15 '08 at 4:34 Dale Ragan 16.1k24469 3 I wrote an ELMAH Tutorial last year, which I think describes this scenario in more detail than the CodeProject article. –ThomasArdal Sep 27 '14 at 18:30 add a comment| up vote 9 down vote I've been using Log4net, configured to email details of fatal errors. It's also set up to log everything to a log file, which is invaluable when trying to debug problems. The other benefit is that if that standard functionality doesn't do what you want it to, it's fairly easy to write a custom appender which can process the logging information as required. Having said

Bookmark or forward it: error handling What's logging and tracing? Logging (sometimes also called tracing) is used to record information about a program's execution for debugging and testing purposes. Developers, testers and support engineers often use logging and tracing techniques to identify software problems, for post-deployment debugging, monitoring live systems and auditing purposes. Logging usually involves writing text messages to log files or sending data to monitoring applications. Advanced and modern handling in asp logging tools also support logging of complex data structures, call stacks, threading behavior and also support real-time monitoring of applications over a network or on a local machine. .NET logging and tracing tools C# Logger C# Logger is a logging tool that supports sending events and messages to the Windows event log. The API is similar to Apache's log4j. CommonData The common data project provides functions principally for ASP.NET projects and includes a logging module and an utility for creating custom event logs. CSharp Dot Net Logger C# .NET Logger is an extensible logging framework written in C# and comes with message queuing and asynchronous logging capabilities. DebugWriter DebugWriter is a simple class to help dump property values to the system console in order to inspect them. Enterprise Library Microsoft's Enterprise Library comes with a .NET logging application block to write messages to the Windows event log, text files, message queue and more. log4net Log4net is a tool to help programmers output log statements to different types of output targets. Log4net is a port of the log4j Apache project. Logger.NET Logger.NET is a logging framework that enables developers to log information such a
