Regions page in the OpenStack view

The Regions page in the OpenStack view displays information about the region, an infrastructure segregation that is used for separating geographic areas. It lets you view capacity and decision support metrics at the region level in OpenStack views.

You can access this page in the TrueSight console using one of the following ways:

  • Select Capacity > Views > Cloud > OpenStack and click the Regions tab
  • In the OpenStack > Cloud page, navigate to the Related Information panel and click the Regions link.

The following figure shows the Regions view page displaying region related information for a selected cloud.

Viewing the OpenStack Regions table

The Regions table lists all regions of the OpenStack view contained in the selected cloud.

Each row corresponds to the OpenStack region and displays the following information. By default, some columns are hidden. You can show or hide columns using the action menuthat is located next to the Regions table title. For more information, see Sorting a table in the TrueSight console.

Viewing detailed information about a region

After you click on the region in the Region column, the details for that region are displayed in the Region Details page. The Region details page displays the following information: 

Region Details table

Section or PanelDescription
General details section

General details, such as region name, type, and a number of elements within it are displayed.

Related Information panel

 Clicking the links in the Related Information panel displays the other information related to the selected region. 

Tags panelDisplays tags, if any, that are associated with the region. You can add tags to the region using the action menuthat is located next to Tags. For more information, see Working with tag filters.
Summary tab

The Summary tab, that is displayed by default, displays details for the selected region in a horizontal summary table, as well as charts. 

Analysis charts: Core metrics for the selected entity are displayed as analysis charts, depending on available data. A link at the bottom of each chart allows you to view the data for a specific resource type. You can download, save an offline copy, annotate, and print the charts. For more information, see Managing charts.

Configuration Details tabThe Configuration Details tab displays the configuration matrix for the selected region.

Using data filters and other controls in tables

You can sort and filter the information that is displayed in tables to suit your need. For instance, you can show or hide columns, export the data to Excel, select a different cloud, clear the selected cloud, and so on.

For more information, see Sorting a table in the TrueSight console and Using filtering options in views in the TrueSight console.
