In a nutshell, it involves four simple steps: Integrating ELMAH into a new or existing ASP.NET application is an easy and straightforward process that takes under five minutes. Adding ELMAH to an ASP.NET Web Application I encourage you to try both systems and decide what one best suits your needs. The health monitoring system and ELMAH both have their own sets of pros and cons. This tutorial walks through the steps involved in adding ELMAH to an ASP.NET application. Furthermore, ELMAH includes support for ASP.NET 1.x, ASP.NET 2.0, and ASP.NET 3.5 applications, and ships with a variety of log source providers. ELMAH is easier to configure than health monitoring because it only logs errors. ![]() The most notable difference between the two systems is ELAMH's ability to display a list of errors and the details of a specific error from a web page and as an RSS feed. You will need to create a custom log provider class should you need to log errors to an alternate data store, such as an XML file or Oracle database.Īn alternative to the health monitoring system is Error Logging Modules And Handlers (ELMAH), a free, open-source error logging system created by Atif Aziz. Moreover, the SqlWebEventProvider class, which we used in the preceding tutorial to logs error details to a database, only works with Microsoft SQL Server databases. NET Framework in version 2.0, it is not available for older web applications built using ASP.NET version 1.x. Because health monitoring was first added to the. Because health monitoring can be used to record a plethora of different events, and because there are a variety of options for instructing how and when events are logged, correctly configuring the health monitoring system can be an onerous task. If you want to see a summary of the 10 last errors, or view the details of an error that happened last week, you must either poke through the database, scan through your email Inbox, or build a web page that displays information from the aspnet_WebEvent_Events table.Īnother pain point centers around health monitoring's complexity. First and foremost is the lack any sort of user interface for viewing information about the logged events. However, there are a few pain points with this system. Many developers use health monitoring to log and email the details of unhandled exceptions. The preceding tutorial examined ASP.NET's health monitoring system, which offers an out of the box library for recording a wide array of Web events. This tutorial walks through downloading and configuring ELMAH. ELMAH is a free, open source error logging library that includes features like error filtering and the ability to view the error log from a web page, as an RSS feed, or to download it as a comma-delimited file. ![]() Error Logging Modules And Handlers (ELMAH) offers another approach to logging runtime errors in a production environment.
