Future Saturations page in the AIX PowerVM view

The Future Saturations page in the PowerVM view displays all partitions that are projected to have CPU, memory, or file system saturation within the next 30 days. The 30 day default can be changed by modifying the 'Future Saturation – Show partitions whose forecasted days to saturation are under or equal to threshold' parameter. All values are calculated over the last full month and the current month.

The PowerVM Future Saturations tab allows you to toggle between viewing future saturation details for:

The following figure shows the Future Saturations tab displaying information on Partitions filtered on all domains.

An example of the Partition Future Saturation table

To view future saturation details for partitions

The Partition Future Saturations table lists future saturation information for all partitions in the selected domain.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.Each row corresponds to a partition and shows the following information.

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, filter tables on particular domains, and so on.
