Proactively monitoring SPS 2010 and MOSS

I was recently introduced to what is now a critical tool. The ULS Viewer http://code.msdn.microsoft.com/ULSViewer

The ULSViewer tool performs various actions against the data from ULS log files in order to better analyze it. ULSViewer allows the user to: 

• Highlight data of importance to the user on the fly
• Bookmark log entries
• Append logs to other logs in order to track trends
• Hide unimportant data
• Only view critical log entries by sorting data by severity
• Write rules to prompt the user when certain events occur
• View your data in a spreadsheet instead of the text file ULS generates
• Monitor remote machines logs that are running ULS services
• Open multiple logs at the same time in order to compare log files.
• Open logs files from multiple machines at the same time.
