The Future Saturation page in the Solaris LDOM view displays all LDOMs and hosts that will saturate either their CPU, memory, or file system space within the next 30 days. All values are calculated over the last full month, and the current month.

To access the page, in the TrueSight console navigation pane, click Capacity Views > Virtualization > Solaris > LDOM, and in the Solaris LDOM page, click the Future Saturations tab. 

The page contains future saturation details for the following subsystems that are grouped under separate tabs: LDOMs and Hosts. Click a tab to view its details.

For more information, see the following sections:

LDOMs page

LDOM Future Saturation table

Each row in the table corresponds to an LDOM and displays the following metrics:

Certain minimum amount of historical data is required to provide accurate Days to Saturation (DTS) values. Therefore, Yesterday and Last 7 days time filter selection is not applied to DTS calculation. DTS calculation is always based on last 30 days of data.

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 tables in views 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
