Hello,

I need to find the free memory in the machine where a SQL server 2008 r2 is installed, and I need to do it via T SQL.
Are the table:
sys.dm_os_sys_info or
sys.dm_os_sys_memory
about this or not? I've found out different opinion in the internet and I've been told that with this query I can only find the RAM available:

select available_physical_memory_kb
from master.sys.dm_os_sys_memory

is this true?
how can I find the total space available in all unit C:/ with a query?
thanks a lot.

Probably, this is what you were looking for!!!


select
Name as 'Database'
, Filename as 'Location'
, convert(numeric(10,2),round(a.size/128.000,2)) as SizeMB
, convert(numeric(10,2),round(fileproperty(a.name,'SpaceUsed')/128.000,2)) as UsedSpaceMB
, convert(numeric(10,2),round((a.size-fileproperty(a.name,'SpaceUsed'))/128.000,2)) as FreeSpaceMB
, convert(numeric(10,4),round(fileproperty(a.name,'SpaceUsed')/128.000,2)/1000) as UsedSpaceGB
, convert(numeric(10,4),round((a.size-fileproperty(a.name,'SpaceUsed'))/128.000,2)/1000) as FreeSpaceGB
from dbo.sysfiles a

The thread is confusing. Are you looking for disk space or RAM?

xp_fixeddrives indeed gives you the available amount of free disk space (not the total space).

If you want to know the total amount of free RAM in the machine, I don't think there is a DMV that exposes this, nor is there any reason why there should be. There is little reason why SQL Server would track what else is going on in the machine. But if there is a command-line command to give you the information, you could invoke it through xp_cmdshell.

True..
XP_Fixeddrives will give actual free disk space on the server.. whereas script I gave above will give detail about size of the file and amount of space that is used by specified file... Sorry for the confusion..
