Database Size - Data and Log :: Used/Free
-
I'm currently writing a report on the databases I currently have on our internal SQL Server 2000 box b/c they will soon be deployed to 2 other sites in 2 different cities. In the report, I am suppose to include the size of each database we have.
My question is, when I right-click on the database via EM, towards the top of the screen under the Database section, I see a set Size amount. Also, under the Space Allocated section, I see 2 amounts, one for Data and one for the Log, and these 2 having Free and Used amounts. So in my report, should I include the overall Size amount, or only use the Used Data amount, or include the Data and Log Used amounts or report both the Used and Free amounts for both Data and Log which is the Size amount given towards the top?
Thanks in advance for any advice.

Depends on what you want. I've tended to include the used and free amounts and a change from the previous day so I can see if things are growing abnormally.
what's the report being used for?

To get the most accurate information (IMO), run the stored procedure sp_updateusage then run sp_spaceused.
sp_spaceused will return the amount of space used by data, unallocated, free, etc.
Refer to the BOL for syntax and more information.

To automate the process use this script:
First put the script into a DTS Package ExecuteSQL Task, create the tables using the scripts at the end of the post. Create linked server connections to the servers you want to report on. Report off the data in the tables. It's fairly accurate.
