Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example
Asp.net Custom Error
shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a request for a nonexistent .html or .jpg file does not cause a redirect to the Http404ErrorPage.aspx file. If you want ASP.NET to handle requests for all file types, you can configure IIS to map file-name extensions to ASP.NET. Note In the example, the mode attribute is set to "On" so that you can error messages when you run the example in Visual Studio. In a production environment, this setting would normally be "RemoteOnly". ASP.NET then renders error pages to external u

How to: Handle Application-Level Errors Other Versions Visual Studio 2010 .NET https://msdn.microsoft.com/en-us/library/24395wz3.aspx 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 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.

Join them; it only 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 receive emails when errors occurs in my application, handling in asp 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 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 9,6572062103 asked Aug 15 '08 at 4:05 Costo 2,83762135 I've also seen System.Web.Management, but I've never used it.

In order to know what is the problem, I want to find the log file and examine it. Where is the location of the ASP.NET Server log file? I couldn't find it in event viewer, so I don't know where else to look asp.net log-files asp.net-mvc share|improve this question asked Dec 1 '09 at 3:57 Graviton 90572446 add a comment| 2 Answers 2 active oldest votes up vote 13 down vote accepted ASP.NET uses IIS logging, so it's really an IIS question. Though there is some detailed info in Event Viewer for some types of events. In IIS6 (and prior), this is located in %SystemRoot%\system32\logfiles, and in IIS7, this is located in %SystemDrive%\inetpub\logs\LogFiles. In both cases, it will be placed in a subfolder called W3SVC{Id}. The Id is the site Id. You can find it by clicking on "Web Sites" in IIS Manager and the site ID will show in that view. share|improve this answer edited Oct 8 '15 at 2:34 Graviton 90572446 answered Dec 1 '09 at 5:43 Scott Forsyth - MVP 13.7k22346 +1 for a more complete answer than my own. Great book btw! –osij2is Dec 1 '09 at 5:53 Thanks osij2is! –Scott Forsyth - MVP Dec 1 '09 at 14:18 does it log the errors too? :) or only event and activities? :) –Zafarbek Jul 17 '14 at 14:07 @Zafar. Error status codes are logged (e.g. 500) but that only tells you that an error occured. It doesn't provide further info. Details would need to be found in Event Viewer. Consider an error logging framework like ELHAM or Log2Net for the best error logging and notifications. –Scott Forsyth - MVP Jul 18 '14 at 3:36 add a comment| up vote 3 down vote I believe this is what you're looking for (link). FTA: IIS uses a flexible and efficient logging architecture. When a loggable event, usually an HTTP transaction, occurs, IIS calls the selected logging module, which then writes to one of
