Every now and then you get a helpful alert from one of your database servers about disk space being low (you're monitoring that, right?), or a bunch of autogrowth alerts (you're monitoring that too, right?) - but what happens when you get these for a database that you don't expect growth in? Further, what happens when that database is growing rampantly (say like 1GB/hr in my case) and it's a canned database from a 3rd party product? This time it was the database that SolarWinds uses for collection - and apparently it was collecting a lot of something that it wasn't collecting before.

As a Database Admin, you can help diagnose the problem by letting everyone know what exactly is growing:
