The bad news is that, according to BOL, "this view is applicable only to the tempdb database".

Very nice question, definately learned something.
And thanks to vk-kirov for pointing out an important remark. I hadn't even noticed it when I read the BOL page.

The bad news is that, according to BOL, "this view is applicable only to the tempdb database".
I would not expect much change in SGAM pages in a normal database. Table creation rates should be low compared to tempdb, so frequent changes in SGAM page allocation is unusual.

I believe this is more important to monitor when you are using Mirroing or Publishing a VLDB.
Also it may be usefull you execute large querries (5K+ rows) that use TEMP tables or Table Parameters that have to create objects to store data in TEMPdB.
