Writing to the SharePoint Unified Logging Service

SharePoint uses a logging service that makes entries in the log files located at Program Files\Common Files\Microsoft Shared\web server extensions\12\LOGS. Out-of-the-box, SharePoint logs almost everything to these files, and I have seen them get quite large. Therefore, you should "throttle" the log writing, which can be done in the "Diagnostic Logging" section of the Central Administration site.

Once you discover the log files, you'll want to be able to write to them from your own features. This is a pretty easy thing to do, because the SharePoint SDK has a complete sample with code you can reuse. I use this code regularly in my features, so I have packaged it into a class that you can download here. Simply add the class to your project and then you can write to the logs using something like the following code.

TraceProvider.RegisterTraceProvider();
TraceProvider.WriteTrace(TraceProvider.TagFromString("XXXX (must be 4 letter tag)"), TraceProvider.StringToSeverity("Exception or Information"), Guid.NewGuid(), "Method Name", "Assembly Name", "Project Name", "Message");
TraceProvider.UnregisterTraceProvider();

Once you start writing to the log files, you'll discover that there is no easy way to view them. SharePoint does not have a log viewer built into the Central Administration web site. I've written an additional feature for viewing logs that you can download from my CodePlex project.

log4net is a tool to help the programmer output log statements to a variety of output targets. log4net is a port of the excellent log4j framework to the .NET runtime. We have kept the framework similar in spirit to the original log4j while taking advantage of new features in the .NET runtime. For more information on log4net see the features document.

log4net is part of the Apache Logging Services project. The Logging Services project is intended to provide cross-language logging services for purposes of application debugging and auditing.
