Is it possible to use ELMAH in a SharePoint environment? - sharepoint

Question

Has anyone integrated ELMAH into their SharePoint environment?
I suppose it's possible as it's all ASP.net, but I just wondered if anyone had done it and if there's a walk through on how to achieve it?

Answer 1

One thing that IS important when setting up ELMAH, or most HTTPModules in Sharepoint is that they need to be at the beginning of the httpModules section. Otherwise SharePoint will essentially swallow the exception and ELMAH functionality will not be invoked
Works
<clear />
<add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah"/>
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
<add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah"/>
<add name="SPRequest" type="Microsoft.SharePoint.ApplicationRuntime.SPRequestModule, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
<add name="OutputCache" type="System.Web.Caching.OutputCacheModule" />
<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" />
... Rest of SharePoint modules....
Does not work

Answer 2

We use ELMAH in our MOSS 2007 environment. Since ELMAH uses HttpHandlers and is set up via the web.config, activating it was a cinch. Just add the ELMAH stuff to the web.config for the application that you're running inside SharePoint.
If you want ELMAH to report errors at a level higher than your custom application, then add it to the SharePoint web.config.

There is no magic to it, just hook it up like you would on any other ASP.NET site.

Answer 4

Following are the config entries that needs to added in web.config of the SharePoint web application
Add under configsection
<configSections>
<sectionGroup name="elmah">
<section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah" />
<section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />
<section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" />
<section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" />
</sectionGroup>
</configSections>
Add connectionstring section
<connectionStrings>
<add name="elmah-express" connectionString="Data Source=[server name];Initial Catalog= [ELMAH_customlogging];User ID=testuser;Password=Welcome1;" />
</connectionStrings>
Add elmah section just below the connectionstring section
<elmah>
<security allowRemoteAccess="0" />
<errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="elmah-express" />
</elmah>
Add handler and module entry in httphandlers and httpmodules section under system.web
<httpHandlers>
<add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah"/>
</httpHandlers>
<httpModules>
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
</httpModules>
Add handler and module entry in handlers and modules section under system.webserver
<modules runAllManagedModulesForAllRequests="true">
<remove name="ErrorLog"/>
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
<add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" preCondition="managedHandler" />
<add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" preCondition="managedHandler" />
<add name="ErrorTweet" type="Elmah.ErrorTweetModule, Elmah" preCondition="managedHandler" />
</modules>
<handlers>
<add name="Elmah" path="elmah.axd" verb="POST,GET,HEAD" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" />
</handlers>
