SharePoint Dragons

You can use the SharePoint Log Investigation Tool (SPLIT) to search SharePoint 2010 logs using a correlation ID. The SharePoint logging has been extended with a new correlation ID that is unique for each request or operation. It is easy using this  correlation ID to track down any unexpected errors because you can search for the correlation ID in the trace logs. This unique ID is also maintained between servers for instance when making a call to a service application. With SPLIT you can use this correlation ID to search logs using a Windows interface or a Web-based interface.
