Unprocessed ASP.NET Errors - Are Records Available?

Question

We had a problem when a .NET error occurred in the root of our application cluster, which circumvented our error handling and displayed a common ASP.NET error message.

Is there anywhere to check to see these errors if it bypasses their logging? (Writing to .NET / IIS by default or something else?)

Thanks.

Answer 1

You should be able to test the application event viewer.

• Right-click My Computer
• Control
• Event Viewer
• Application

The assumption here is that it bubbled up and was not found anywhere.

Answer 2

// Inside your logger constructor: AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(AppDomainUnhandledException); // Then: private void AppDomainUnhandledException(Object sender, UnhandledExceptionEventArgs e) { // Log as unhandled exception: e.ExceptionObject.ToString() }

If you are using IIS7, you can add a failed request trace through IIS Manager. For more information, see the following article:
