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, and can be viewed in either Graphic View or Table View, which includes the following:
  • Temperature
    • Display real time ambient temperature and the key component temperatures.
    • Hovering the mouse cursor over a memory module will show its current temperature.
    • The History tab displays the historical temperatures charts for up to the past 24 hours.
  • Power Utilization
    • Display current power consumption pie chart, as well as the historical power consumption charts for up to last 24 hours.
    • Hovering the mouse cursor over the pie chart will show its current power consumption.
    • Current power consumption pie chart consists of four categories: CPU, Memory, Other and Spare. “Other” means the total system power consumption minus CPU and Memory power consumption. “Spare” means the total available allocated power minus the total system power consumption.
    • Voltage tab displays the current voltage readings and status on all voltage sensors supported by hardware.
  • System Utilization
    • Represents the current utilization snapshot of the system, processor, memory and I/O subsystems.
    • Use the browser refresh or reload function to update the current utilization data.
    • CPU subsystem-level utilization represents the percentage of the total CPU bandwidth currently in use, as measured by the performance counters built in the CPU (it might differ slightly from the CPU utilization reported by the operating system).
    • Memory subsystem-level utilization represents the percentage of total memory channel controller bandwidth currently in use. (It doesn't reflect the amount of memory currently being used).
    • I/O subsystem-level utilization represents the percentage of total PCIe traffic bandwidth currently in use.
    • Measured bandwidth calculated as a percentage of the used and max memory bandwidth available (per second).
  • Fan Speed (RPM)
    • The fan speed section shows the fan speeds as a percentage of the maximum speed.
    • User can click on the gear icon to access Fan Speed Boost options.

      • This setting allows additional cooling to the server based on ambient temperature. It can increase the fan over normal speed by controlled thermal algorithm. There Will be no change if fan already running at full speed
