SBC CPU Usage Screen in Hardware-based Platforms
The CPU Usage window shows CPU usage, on a percentage basis, in a table and chart format.
From the SBC main screen, go to Monitoring > Dashboard > CPU > CPU Usage, or Monitoring > System > Category: Hardware Status > CPU Usage.
The CPU Usage window displays.
Figure 1: CPU Usage
The following parameters display:
Table 1: CPU Usage Parameters
| Parameter | Description |
|---|---|
| CPU | CPU number. |
| % User | Specifies the percentage of CPU utilization that occurred while executing at the user level. |
| % Nice | Specifies the percentage of CPU utilization that occurred while executing at the user level with nice priority. |
| % Sys | Specifies the percentage of CPU utilization that occurred while executing at the system level (kernel). |
| % IO Wait | Specifies the percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request. |
| % IRQ | Specifies the percentage of CPU serving for the hardware interrupts. |
| % Soft | Specifies the percentage of CPU serving for the software interrupts. |
| % Steal | Specifies the amount of CPU ‘stolen’ from the virtual machine by the hypervisor for other tasks (such as running another virtual machine) this will be 0 on desktop and server without Virtual machine. |
| % Guest | Specifies the percentage of CPU serving for the guest virtual machine. |
| % Idle | Specifies the percentage of time that the CPU(s) is idle and the system did not have an outstanding disk I/O request. |
The same parameters are displayed in a chart format.

CPU Usage Screen in SBC SWe - Software-based Platforms (Virtual and Cloud)
The SBC SWe Virtual and Cloud platforms adds the Average CPU Usage Table and the Average CPU Usage Chart in addition to the Individual CPU Usage table and chart.
Web UI Path: Monitoring > Dashboard > CPU > CPU Usage, or Monitoring > System > Category: Hardware Status > CPU Usage.
The layout of CPU Usage screen displays the table and chart in the following sequence:
- Individual CPU Usage Table
- Average CPU Usage Table
- Individual CPU Usage Chart
- Average CPU Usage Chart
The average CPU Usage table and average CPU Usage chart refreshes every 5 seconds.
