Top/Bottom LDOMs page in the Solaris LDOM view

The Top/Bottom LDOMs page in the Solaris LDOM view displays logical domains (LDOMs), ranked by their resource utilization.

To access the page, in the TrueSight console navigation pane, click Capacity Views > Virtualization > Solaris > LDOM, and in the Solaris LDOM page, click the Top/Bottom LDOMs tab.

The utilization sort order is determined by a blended value based on the CPU, memory, and file system space used. The blended value is calculated using the following formula:

(LDOM_CPU_COST x [CPU Used]) + (LDOM_MEMORY_COST x [Memory Used]) + (LDOM_STORAGE_COST x [File System Used])

The Top/Bottom LDOMs table lists all the Solaris logical domains .

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:

Top/Bottom LDOMs table

Each row in the Top/bottom LDOMs table corresponds to an LDOM and displays the following metrics:

Field

Description

Statistical
Type
Metrics 

Rank

A unique numerical index that classifies all existing VMs in terms of resource (CPU, memory, disk) consumption. The higher the number, the higher the resource consumption. The rank for the IVM is based on the blended value computed as described at the top of this page.

To view details for a specific LDOM

To view the details page for a particular Solaris LDOM, click its (hyper-linked) name under the LDOM column. You can use the sorting and filtering options on the page to find a specific LDOM. 

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

The LDOM Details page displays information for the selected LDOM under the following sections or panels:

Section or PanelDescription
Summary page

A quick graphical summary of the CPU and memory utilization, and disk and network I/O rate of the LDOM. 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 other time filter options to view charts over a different time resolution.

For more information, see LDOM Domain page in the Solaris Data Explorer view.

Configuration Details pageConfiguration information about the host.
File Systems pageDisplays the file system summary table. For more information, see File systems table.
Related Information panel

Links to detailed pages for thresholds, process profile, workload profile, command profile, and user profile. For more information, see Viewing related information.

Tags panelList of tags that are associated with the host. You can assign or remove tags by using the Edit Tags option from the Tags action menu.
