V Sentry Performance Metrics

This article covers the various performance metrics displayed by the Performance Analysis Dashboard and Performance Analysis Overview, and how to interpret different metric values and combinations of values across different metrics for V Sentry.

Note:  For Mode: S = Sample and H = History.

Note:  We are actively adding information to the performance metrics tables to complete data for undefined metrics.

VMware Host Metrics

SectionMetricDescription
CPUReadyPercentage of time that the virtual machine was ready, but couldn't get scheduled to run on the physical CPU. CPU ready time is dependent on the number of virtual machines on the host and their CPU loads.

MemoryActiveAmount of memory that is actively used, as estimated by VMkernel based on recently touched memory pages.

MemoryConsumedAmount of machine memory used on the host. Consumed memory includes memory used by the service console, the VMkernel, vSphere services, and the total consumed metrics for all running virtual machines.
