Use Memory attributes to create situations that monitor counter information for real and virtual memory. Memory is a multiple-instance attribute group. You cannot mix these attributes with those of any other multiple-instance attribute group. This attribute group is superseded. There is a new attribute group with the same name that replaces it.
% Committed Bytes In Use The ratio of Committed Bytes to the Commit Limit. Committed memory is the physical memory in use for which space has been reserved in the paging file should it need to be written to disk. The commit limit is determined by the size of the paging file. If the paging file is enlarged, commit limit is enlarged, the commit limit increases, and the ratio is reduced. This counter displays the current percentage value only; it is not an average. (Superseded.)
