Viewing the System Utilization

By clicking Utilization in the left pane, a summary of common server utilization information is provided.

System utilization is a composite metric based on the real-time utilization of processor, memory, and I/O subsystems. The utilization data are all coming from the ME(Node manager) side, which includes the following:
  • CPU Utilization
    • Aggregated C-State Residency
    • Measured time in C0 as a percentage of the used and max C0 residency (per second).
  • Memory Utilization
    • Aggregated R/W volume of all Memory Channels.
    • Measured bandwidth calculated as a percentage of the used and max memory bandwidth available (per second).
  • I/O Utilization
    • Aggregated R/W volume of Root Ports in the PCIe* Bus.
    • Measured bandwidth calculated as a percentage of the used and max I/O bandwidth available (per second).
