Memory Available Megabytes Windows Server 2012

Microsoft.Windows.Server.6.2.OperatingSystem.MemoryAvailableMBytes.Collection (Rule)

Collects the performance counter Memory\Available MBytes

Knowledge Base article:

Summary

This rule collects performance data for the Memory\Available Mbytes performance counter.

The Physical Disk\Pages Writes/sec performance counter exposes the amount of physical memory available to processes running on the computer, in Megabytes, rather than bytes as reported in Memory\Available Bytes. It is calculated by adding the amount of space on the Zeroed, Free, and Stand by memory lists. Free memory is ready for use; Zeroed memory are pages of memory filled with zeros to prevent later processes from seeing data used by a previous process; Standby memory is memory removed from a process' working set (its physical memory) on route to disk, but is still available to be recalled. This counter displays the last observed value only; it is not an average.
