Exploring top resource analyzers
The Top Analyzer views appearing on the individual tabs of the managed server details view and PowerVM VIOS details view identify the partitions with the highest resource entitlement, utilization, and usage, and the physical adapters with the highest network throughput. Use them it to find out if any of the logical partitions running on the selected managed server or associated with the selected PowerVM VIOS show the signs of processor, memory, or disk space exhaustion or poor utilization, or unusually high network activity. This can help you maintain the stability of your system and ensure optimum resource usage.
To navigate to this tab, in the Selected Service PowerVM view, select a managed server or a VIOS, and click Explore. Open the CPU (managed servers only), Memory (managed servers only), Storage, or Network tab, and open the Top CPU Analyzer (managed servers only), Top Memory Analyzer (managed servers only), Top Storage Analyzer, or Top Network Analyzer tab.

When Entitlement is selected, the Total CPU Resource areas in the graph represent the number of processing units allocated to the PowerVM partitions that are associated with the managed server. When Utilization is selected, the areas in the graph represent the percentage of the managed server processor resources allocated to the partitions that are associated with the server and in use over the selected time range. When Usage is selected, the areas in the graph represent the number of processing units allocated to the partitions associated with the managed server that are in use over the selected time range. | ||
|
When Entitlement is selected, the Total Memory Resource areas in the graph represent the amount of memory resources allocated to the PowerVM partitions that are associated with the managed server. When Utilization is selected, the areas in the graph represent the percentage of the managed server memory resources allocated to the partitions associated with the server that are in use over the selected time range. When Usage is selected, the areas in the graph represent the amount of memory resources allocated to the partitions associated with the managed server that are in use over the selected time range. | ||

Top CPU Analyzer and Top Memory Analyzer only. Indicates if the processor or memory resources allocated to the PowerVM partition are participated in shared processor or memory pools (Shared), or are dedicated specifically to that partition (Dedicated). | ||
Exploring PowerVM VIOS network summaries
The Summary tab on the Network tab of the PowerVM VIOS detail view provides information all network adapters associated with the selected PowerVM® VIOS, shared ethernet adapters, virtual ethernet adapters, and physical ethernet adapters. Use it to find out if any specific collection of adapters exhibits low throughput, high levels of dropped packets or errors, to maintain the stability of your system and ensure optimum network throughput levels.
To navigate to this tab, in the Selected Service PowerVM view, select a PowerVM VIOS, and click Explore. Open the Network tab, and open the Summary tab.
Drilling down on shared network adapters
The Shared Ethernet Adapter Details view provides information about all shared network adapters associated with the selected PowerVM® VIOS. A shared network adapter enables multiple PowerVM partitions to share one adapter, to optimize the overall use of physical resources. Use it to find out if the adapters exhibits low throughput, high levels of dropped packets or errors, to maintain the stability of your system and ensure optimum network throughput levels. You can also use this view to review the PowerVM partitions that use these adapters, and to review their settings.
To navigate to this view, in the Selected Service PowerVM, select a PowerVM VIOS, and click Explore. Open the Network tab, click Summary, and in the Shared Ethernet Adapters Summary area, click View SEA Details.

Drilling down on physical and virtual network adapters
The Network - Virtual Ethernet Adapters Detail and Network - Physical Ethernet Adapters Detail views provide information about physical and virtual network adapters associated with the selected PowerVM® VIOS. Use it to find out if the adapters exhibits low throughput, high levels of dropped packets or errors, to maintain the stability of your system and ensure optimum network throughput levels.
To navigate to these views, in the Selected Service PowerVM view, select a PowerVM VIOS, and click Explore. Open the Network tab, and then open the Summary tab. In the Virtual Ethernet Adapters Summary area, click View VEA Details, to see the Network - Virtual Ethernet Adapters Detail view. To access the Network - Physical Ethernet Adapters Detail view, in the Physical Ethernet Adapters Summary area, click View PEA Details.
