Hi John,
Can you elaborate on what you're trying to accomplish and how?
In general, you can get detailed stats on memory utilization using 'tmsh show sys memory'. The total graphs in 10.2.x are comprised of these metrics:
tmsh show sys memory|head
Sys::System Memory Information
Memory Used(bytes) Current Average Max(since 08/05 14:19)
------------------------------------------------------------
Total Phys Memory 3.9G 3.9G 3.9G
OS Used Memory 3.0G 3.0G 3.0G
TMM Alloc Memory 1.7G 1.7G 1.7G
TMM Used Memory 67.0M 67.0M 67.1M
