Knowledge Base article:

Summary

This rule collects performance data for the Memory\Used Memory MBytes performance counter. The collected values are accessible in performance views and reports.

This metric exposes the total amount of memory currently in use by the system in megabytes.

The used megabytes memory value is calculated by subtracting available memory (MemFree, Buffers and Cached) from total physical memory.
