I'm looking into the restriction of access rights (via "guest" and "public") in the master database, and have a question. In the list of procedures to remove access to, you list "xp_perfmonitor". What is this procedure? What does it do? And why can't I find it in the master database, the Microsoft web site, or anywhere on Google that doesn't show the exact same list?

Oh.

I (mostly) figured it out while writing the question, but will still post it for potential discussion purposes.
