How to monitor Available Bytes for WMI Win32_PerfRawData_PerfOS_Memory ?

With IPHost Network Monitor you can run WMI Available Bytes monitoring of various devices in your network.

To create a WMI monitor for Available Bytes, provide host name (it must be a Windows host) and specify custom WQL query:

SELECT AvailableBytes FROM Win32_PerfRawData_PerfOS_Memory

Available Bytes is the amount of physical memory, in bytes, immediately available for allocation to a process or for system use. It is equal to the sum of memory assigned to the standby (cached), free and zero page lists. For a full explanation of the memory manager, refer to MSDN and/or the System Performance and Troubleshooting Guide chapter in the Windows Server 2003 Resource Kit.

The Memory performance object consists of counters that describe the behavior of physical and virtual memory on the computer. Physical memory is the amount of random access memory on the computer. Virtual memory consists of the space in physical memory and on disk. Many of the memory counters monitor paging, which is the movement of pages of code and data between disk and physical memory. Excessive paging, a symptom of a memory shortage, can cause delays which interfere with all system processes.
