Current Resource Utilization graphs

The upper section of the Performance Monitoring home page includes the Current Resource Utilization information. These graphs depict how the system's processor usage, memory assignment, virtual I/O network, and storage traffic compare against the available capacities or against their maximum historic highs. If the overall server usage is consistently high, activate more processors, move workloads to other servers, or buy more servers, processors, or memory.

The Current Resource Utilization information includes the following graphs: Processor Usage/Peak, Memory Assignment, Network Traffic, and Storage Traffic.

Processor Usage/Peak

The Processor Usage/Peak graph shows the average processor usage that is measured in processor cores and is represented by the blue horizontal bar. The black vertical bar indicates the maximum number of processors that the system used during the most recent monitoring period. The gray shading indicates the percentage of total active physical processors used. Light gray indicates that zero to 50% of the available processors were used. Medium gray indicates that 51% - 90% of the available processors were used. Dark gray indicates that 91% - 100% of the available processors were used. This graph indicates how the current and recent peak utilization compares against the total number of processors available on the server.

Click the Click to Enlarge button in the Processor Usage/Peak area. The table displays information about the Installed, Activated, Allocated, Available, Utilized, Peak, and Minimum usage data of processor usage.

Memory Assignment

The Memory Assignment graph shows the average memory assignment that is measured in MB or GB and is represented by the blue horizontal bar. The black vertical bar indicates the maximum amount of memory that the system used. The gray shading indicates the percentage of total active memory used. Light gray indicates that 0% - 50% of active memory was used. Medium gray indicates that 51% - 90% of active memory was used. Dark gray indicates that 91% - 100% of active memory was used. This graph indicates how the current and recent peak utilization compares against the total amount of memory available on the server.

Click the Click to Enlarge button in the Memory Assignment area. The table displays information about the Installed, Activated, Allocated, Available, Utilized, Peak, and Minimum memory assignment. You can also view information about the Assigned Virtual Persistent Memory. The persistent memory is available only when the Hardware Management Console (HMC) is at Version 9.1.940, or later, and when the firmware is at level FW940, or later. The persistent memory is a virtualization feature in which persistent memory volumes are created by using the existing DRAM (Dynamic Random Access Memory), where data persistence is maintained across applications, and the operating systems even when the logical partition has been restarted.

Network Traffic

The Network Traffic graph shows the average amount of traffic (measured in KB/s or GB/s and is represented by the blue horizontal bar) that flows through the network adapters that are assigned to the Virtual I/O Server. The gray shading indicates the maximum amount of traffic that was measured in the time that elapsed since the console was started. The black vertical bar indicates the maximum amount of network bandwidth that the system used. This graph indicates how the average network traffic compares against the maximum amount of network bandwidth that the system used.

Click the Click to Enlarge button in the Network Traffic area. The table displays information about traffic utilization that is measured per second (measured in KB/s or GB/s), the maximum amount of network bandwidth that the system used, the number of Virtual I/O Servers, and the number of Physical Adapters.

Storage Traffic

The Storage Traffic graph shows the average amount of traffic (measured in KB/s or GB/s and is represented by the blue horizontal bar) that is processed through the storage adapters and assigned to the Virtual I/O Server. The gray shading indicates the maximum amount of traffic that was measured in the time that elapsed since the console was started. The black vertical bar indicates the maximum amount of storage I/O bandwidth that the system used. This graph indicates how the average storage traffic compares against the maximum amount of storage I/O bandwidth that the system used.

Click the Click to Enlarge button in the Storage Traffic area. The table displays information about storage utilization that is measured per second (measured in KB/s or GB/s), maximum amount of storage I/O bandwidth that the system used, the number of Virtual I/O Servers, and the number of Physical Adapters.
