Investigating the use of PowerVM partition and VIOS processor resources
The CPU tab of the Partition detail view or VIOS detail view shows the amount of processor resources dedicated to the selected object and their entitlement mode. It also shows the top processor consumers on the host, the top processes’ utilization trends, and illustrates the processor load.
To navigate to this tab, in the Selected Service PowerVM view, select a PowerVM® partition or a VIOS, click Explore, and in the view that appears, open the CPU tab.

Clicking this link displays the All Partitions in Pool dialog box that lists all PowerVM partitions that use this processor pool, their entitlement, utilization, and usage. | ||
Investigating the use of PowerVM partition and VIOS memory resources
The Memory tab of the Partition detail view or VIOS detail view shows the amount of memory resources dedicated to the selected PowerVM® partition or PowerVM VIOS, their entitlement model, and identifies the managed server on which the partition is running. It also shows the overall memory utilization on the selected partition and the amount of memory the top processes are consuming. The Top Memory Consumers table lists both resident and virtual sizes for the top processes.
To navigate to this tab, in the Selected Service PowerVM view, select a PowerVM partition or PowerVM VIOS, click Explore, and in the view that appears, open Memory tab.

Exploring processor, memory, and storage breakdowns
The Breakdown views on the CPU, Memory, and Storage tabs of the managed server details view, and on the Storage tab of the VIOS details view show the amount of processor, memory, and storage resources the selected managed server or PowerVM® VIOS uses from the Global Default Pool over the selected time range. Use this view to find out how the selected object uses the allocated resources, and if there are any patterns indicating their usage levels that may potentially compromise the stability of your infrastructure.
To navigate to this tab, in the Selected Service PowerVM view, select a managed server, or a PowerVM VIOS, and click Explore. Open the CPU (PowerVM servers only), Memory (PowerVM servers only), or Storage tab, and then open the Breakdown tab.
Investigating volume-based storage pools
PowerVM® managed servers and PowerVM virtual I/O servers typically rely on volume-based shared storage pools to efficiently use system resources and increase their overall utilization. When you explore the managed server and PowerVM VIOS Storage Breakdown views, you can drill down on a volume-based storage pool to see the logical volumes that belong to it, the PowerVM partition associated with them, their size, and other details, in the Details Of Volume Based Pool view. This view also displays general information about the selected disk pool, such as its size, the managing VIOS, and identifies the hard disks on which the containing logical disk partitions. Use this view to find out the sizes of individual volumes and their association with PowerVM partitions, when needed.
To navigate to this view, in the Selected Service PowerVM view, select a managed server or a PowerVM VIOS, and click Explore. Open the Storage tab, and in the Volume Based Pool Entitled view, click the title bar of the volume-based pool that you want to investigate.
