Current Resource Utilization graphs
The upper section of the Performance and Capacity Monitor 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.
The Processor Usage/Peak graph
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.
The Memory Assignment graph
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.
The Network Traffic graph
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 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.
The Storage Traffic graph
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 flows through the storage adapters 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.
