I made this a question thread.

Disk total space is not something to find in a performance monitor. Because it isnt something which moves up and down. Disk total space is configuration data basically. When a disk is discovered as for instance a windows server logical disk by the windows operating system management packs they are stored in SCOM as discovered data with a number of properties. SUch as their size.

Try this as example:
SCOM console - monitoring pane.
On the left go to almost the top and find: DIscovered Inventory.
Next on the far right click the Select Target.
wait for it to load and type: Logical Disk.
right below it select the option to Show All Targets.
You will see a list of logical disk related classes. Find the Windows Server 2012 Logical Disk class for instance and select it and click OK.
Wait for a bit until it loads the disks and one of the colums should show the size of those found disks.
