Sufficient memory is essential for efficient operation of a computer. We recommend that you consider using the following monitor.

 

Class Monitor name

Windows Server 2008 Operating System

Available Megabytes of Memory

Windows Server 2003 Operating System

Available Megabytes of Memory

Available Megabytes of Memory

Available Megabytes of Memory is the amount of physical memory, in megabytes, 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 more information about the memory manager, see MSDN, or the System Performance and Troubleshooting Guide chapter in the Windows Server 2008 Resource Kit or the Windows Server 2003 Resource Kit.

The default threshold is 2.5MB, a sample is taken every 2 minutes, and three samples are taken to compute the threshold. This monitor is considered Healthy when available memory is above the threshold and Critical when it is below the threshold.
