Hey Jason,

Attached is the custom Server report that you might find useful. As Denis explained, place the file in your "inc" directory and you will see a new "Local" tab appear in the Reports section of RackTables. The query uses several sub-selects but I found this necessary to do it right.

Please send your feedback and any improvements back to the list!
