Metric Definitions in

vRealize Operations Manager 1

Metric denitions provide an overview of how the metric value is calculated or derived. If you understand the metric, you can beer tune vRealize Operations Manager to display results that help you to manage your environment.

vRealize Operations Manager collects data from objects in your environment. Each piece of data collected is called a metric observation or value. vRealize Operations Manager uses the VMware vCenter® adapter to collect raw metrics. vRealize Operations Manager uses the vRealize Operations Manager adapter to collect self-monitoring metrics. In addition to the metrics it collects, vRealize Operations Manager calculates capacity metrics, badge metrics, and metrics to monitor the health of your system.

All metric denitions are provided. The metrics reported on your system depend on the objects in your environment. You can use metrics to help troubleshoot problems. See the vRealize Operations Manager User Guide.

Changes in Metric Availability

The CPU Demand of Recommended (%) metric is no longer available in vRealize Operations Manager version 6.x. To approximate the metric, create a super metric using the following calculations, and add it to your Views and Reports as needed.

( (CPU|Stress Free Demand (MHz)) × (CPU|Current Size in Unit(s)) ) ÷ ( (CPU|Recommended Size

(vCPUs)) × (CPU|Current Size (MHz)) )

For more information about super metrics, see the vRealize Operations Manager Information Center.

Metrics for vCenter Server Components

vRealize Operations Manager connects to VMware vCenter Server® instances through the vCenter adapter to collect metrics for vCenter Server components and uses formulas to derive statistics from those metrics. You can use metrics to troubleshoot problems in your environment.

vCenter Server components are listed in the describe.xml le for the vCenter adapter. The following example shows sensor metrics for the host system in the describe.xml le.

<ResourceAttribute key="currentValue" nameKey="1360" dashboardOrder="1"

Each ResourceAttribute element includes the name of a metric that appears in the UI and is documented as a Metric Key.
