I think you need to create an Extended Object which queries this data. Are you familiar with blquery? (try "man blquery" in NSH). My guess is that you'd have to create a centrally-executing Extended Object which ran 'blquery' against TARGET.HOST to query the information you're looking for.
In the man page for 'blquery' there's a section on "SYSTEM STATISTICS FUNCTIONS (NTOP VALUES)" that might give you what you're looking for.
