I am trying to find a good way to get available RAM percentage from perfmon. I can get Available Mbytes but I can't find any way to get the total installed memory on the server or what is in use via perfmon. I can obviously alert on GB but each of my servers have different total RAM so not a great alert.
The way I understand % Committed Bytes is this includes page files on disk so this is not a good indicator.
Any help would be appreciated.
