Hosts page in the vSphere Infrastructure view

The Hosts page in the vSphere Infrastructure view shows details for all hosts.

To access the page, in the TrueSight console navigation pane, click Capacity Views > Virtualization > vSphere > Infrastructure, and in the vSphere Infrastructure page, click the Hosts tab.

The data in the page is categorized based on different subsystems and grouped under separate tabs. Click a tab to view the metrics for that subsystem: 

  • Capacity
  • Other

Metrics per host are displayed in a tabular format.

By default, some columns are hidden. You can show or hide columns using the action menuthat is located next to the table title.

This topic contains the following sections:

Capacity page

Capacity metrics are displayed in the Capacity page. The Capacity tab is displayed by default, each time you access the Hosts page.

Each row corresponds to a vSphere host and displays the following metrics.

CPU Util [%]

Percentage of CPU capacity utilized by the vSphere host.

95th percentileCPU_UTIL 
CPU Pressure1

A value between 0 and 100, calculated using CPU utilization and CPU ready time. This value must always be greater than or equal to CPU Utilization %. If this is much higher than CPU Utilization %, then it indicates that some VMs in the cluster are starved for CPU (high CPU ready time). See Virtual Machine view > Watchlist page in the vSphere Virtual Machines view to identify them.

Memory Util [%]

Percentage of total memory used by the vSphere host.

95th percentileMEM_UTIL
Composite Memory Util [%]1

An estimate of the amount of memory that is effectively in use in the host or cluster, expressed in percentage; it is computed using the memory pressure indicator. This value is lower than Memory Utilization due to the lower impact of other memory demand parameters, like ballooning and swapping.

For more information, see Computation details for VMware metrics.

A quick graphical summary of the CPU and memory utilization, and disk I/O and network rate for a selected host. Core metrics for the selected entity are displayed as analysis charts, depending on available data. At the bottom of each chart is a link that takes you to the Data Explorer view for the specific resource type, and displays charts and information for a larger set of metrics.

 

The data displayed in Data Explorer view charts for any resource part of this view category, is based on the time filter that is applied to the primary view in this tab. You can select Advanced time periods (other than default/basic) from the Data Explorer view for the selected resource, to view charts over a different time resolution.
