Datacenter Overview view

Datacenters are centralized repositories (physical or virtual) where you store and manage data and information pertaining to your business processes. The Datacenter Overview view facilitates you to view utilization details of one or more datacenters, and enables you to perform the following:

  • View all types of computer infrastructure, virtual and physical. The infrastructure may be used for cloud or enterprise.
  • Plan and organize physical and virtual computers, by physical location, organization, domain, or business service.
  • Navigate quickly to a specific system, by filtering the information based on a variety of parameters, including performance metrics and system category.

You can use Datacenter Overview to make informed decisions regarding datacenter capacity management by analyzing a wide range of details, such as CPU performance and capacity, physical memory utilization and capacity, location, and more.


To access Datacenter Overview in the TrueSight console, in the navigation panel, select > Capacity > Views > Datacenter > Overview.

An example of the Datacenter Overview view


Ensure that the administrator has completed the following tasks:

For information about views in the TrueSight console, see Accessing and using capacity views in the TrueSight console.

Certified data sources

The certified data sources for these views are as follows:

  • BMC - TrueSight Capacity Optimization Gateway VIS files parser
  • VMware - vCenter Extractor Service
  • VMware - vCenter and ESX Server History Extractor

You must configure and run one of these ETL modules to import data into the view. For more information, see BMC - TrueSight Capacity Optimization Gateway VIS files parser and VMware vCenter ETLs.

If you are importing data from an ETL module other than the certified data source, then ensure that you have all the metrics populated in the ETL module so that the view shows the data.

The following video (4:10) provides a brief introduction of the Datacenter views.

Using the Datacenter Overview view

The Datacenter Overview view is split into following pages:

  • Physical Servers: The Physical Servers page in the Datacenter Overview view provides an overview of the utilization of all physical servers in your environment.
  • Virtual Machines: The Virtual Machines page in the Datacenter Overview view provides an overview of the utilization of all Virtual Machines in your environment.
  • Clusters: The Clusters page in the Datacenter Overview view provides an overview of the utilization of all clusters in your environment.

Each view page is further split into the following two sections:

  • CPU Util
  • Memory Util

Filtering the Map based on Overviews

The Datacenter Overview enables you to filter and view datacenter details based on the following overviews:

  • Domain (default): Displays the tree map where each block in the tree map represents a configured domain.
  • Business Service: Displays the tree map where each block in the tree map represents a business services.
  • Organization: Displays the heat map where each block in the tree map represents an organization.
  • Location Site: Displays the tree map where each block in the tree map represents a physical location of a system in the datacenter.

You can use the Overview filter independently, or in combination with other filters present in the view page.

Reading the tree map in Datacenter Overview view

Each outer rectangle represents the parent entity and the inner rectangles are the child entities, as shown in the following image:

The size of the cells denotes the capacity size on that entity.

The color of the cells denotes the usage percentage of that entity, with white indicating no usage and red indicating high usage. The color legend is displayed at the top of the tree map, as shown in the following image:

To view entities with free resources

By default, the tree map does not show the free resources of entities. To view the free resources that are available, you must change the map layout.

In the Datacenter Overview view, click next to Map Layout and click Map Layout with Free Resource.

The Datacenter Overview shows the free resources, as denoted by the white color:

To view details of an entity

You can drill down further into each entity for more details. To view the details, do the following:

Click the required entity.

A Details popup window opens. It lists the Name, Type, Utilization (%) and Size of the entity, along with Drill Down links.

Similarly, you can view the details of each child entity within a parent entity.

To perform drill down of the required entity

You can perform drill down of an entity to view more details of the required entity and not display the others. To do this, do one of the following:

  • Double-click the required entity.
  • Click the parent cell. In the Details popup window that opens, click the Drill Down link.

The following graphic shows how to perform drill down to view entities with high utilization.

Navigate back to the parent entity

In the child entity page, the navigation path from the source section is listed at the the top-left of the tree map. Click the parent entity name in the listed path to go to that entity.

Using time filters in Datacenter Overview view

You can view data for predefined defined time periods. By default, data for the Last 30 days is shown. To view data for a different time period, use the available time filters.

In the Treemap view, click the action menu  next to the time filter and select a time period as shown in the following image:

You can select from the following options:

  • Yesterday
  • Last 7 days
  • Last 30 days

Data for the selected time period is displayed.
