This topic provides information about what is available in the Performance tab.

The Performance tab appears when a vSphere Host is selected, and, if the VMs running on the host have vRealize Hyperic agents running, for each VM, and for the managed resources running in the VMs.

The contents of the Performance tab are updated once per minute.

If a VM does not have an agent running in it, no Performance tab appears. You can view the VM metrics in its Monitor page in the Resource Hub. Click view resource next to the Hostname property on the VM's Summary tab.

View Metrics

The Performance tab displays an Availability bar, and a chart for each metric currently enabled for the selected resource type.

The tables in VMware vSphere Host Metrics list supported vSphere metrics and default settings.

Twelve-hour history is displayed by default. You can use the Data Range pull-down to set the display range to the most recent:

  • 1, 4, or 12 hours

  • 1 or 2 days,

  • 1 week, or

  • 1 month

Correlate Metrics

On the Performance tab for a VM or an vRealize Hyperic agent-managed resource running in the VM, you can use the Compare pull-down to correlate the selected resource's performance with its parent or grandparent. You can:

  • Compare each VM metric with its vSphere Host equivalent — For example compare the VM's "Disk Usage (Average)" metric to its host's "Disk Usage (Average)" metric; the VM's "CPU Usage (Average)" metric to its host's "CPU Usage (Average)" metric; and so on.

  • Compare each VM metric to a selected vSphere Host metric — For example, compare each VM metric to the "Disk Usage (Average)" metric of its vSphere host.

  • Compare metrics for a managed resource in the VM with performance of the VM or the vSphere host — Use the Compare pull-down to select a VM or Host metric - the charts for the managed resource metrics will be overlayed with the line for the selected VM or host metric.
