James is using 3.2.5...this small SQL file was never ported, but it is never used. It breaks the link he mentions, though. I was confused as there's a monitoring package in 4.x which also has't been ported and is up for grabs if anyone's interested!
The 3.2.5 table and function were so simple I just rewrote them and committed them a couple of minutes ago - try it again, James!
