ELMAH - Error Logging Plugin for your .Net Apps

Error Logging Modules and Handlers (ELMAH)

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 supports ASP.NET 1.x, ASP.NET 2.0 and ASP.NET 3.5 applications and ships with a variety of log source providers like XML or database.

Few of its features are –
• Logging of nearly all un-handled exceptions.
• A web page to remotely view the entire list of recoded exceptions and
then 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 and an
RSS feed of the last 15 errors from the log.
• Log errors to several back-end storages like Microsoft SQL Server,
Oracle (OracleErrorLog), XML files, etc.
• Filter unwanted exceptions, programmatically and via configuration.
• Use MsAjaxDeltaErrorLogModule to log errors during partial updates
enabled by Update Panel in Microsoft ASP.NET AJAX.
