Memory

Load

Memory Usage

GB

Memory used in GB

Memory

Utilization

Memory Utilization

%

The host memory used by the processes (both userspace and kernel space) including the OS overhead like as buffers, caches etc.  Depending on environmental load and host resources, OS overhead can inflate actual memory utilization metrics.  In this situation, using Logical Memory Utilization will be more accurate.

Memory

Load

Memory Load

GB

Sum of memory used and page faults generated in GB

Memory

Load

Logical Memory Usage

GB

Memory used in GB  excluding buffers and cache

Memory

Utilization

Logical Memory Utilization

%

The host memory used by the processes (both userspace and kernel space) excluding the OS overhead like buffers, caches etc.  As the memory used by OS overhead could be reallocated to userspace processes if needed, its exclusion gives us a good estimate of how much memory is available for starting new applications, without swapping.
