monitor cpu-usage

Function

The monitor cpu-usage command dynamically monitors CPU usage and displays CPU usage on at a fixed place of the screen.

The monitor process information command dynamically monitors the usage of system process resources.

Format

display cpu-usage [ slot slotid ]

monitor cpu-usage [ slot slotid ] [ interval intervalValue ]

monitor process information [ slot slotid ] [ interval intervalValue ]

Parameters

Parameter	Description	Value

Usage Guidelines

Usage Scenario

When a network configuration is changed (for example, system software of network devices is upgraded), you need to monitor CPU usage of the device in real time. At present, the dynamic CPU usage is displayed using the display cpu-usage command repeatedly, which is unable to display the real-time CPU usage and increases the maintenance workload. To reduce the maintenance workload and implement real-time CPU usage, you can run the monitor cpu-usage command.

System process resources include CPU, memory, timer, handle, and thread resources. To monitor the usage of system process resources, run the monitor process information command.

During the dynamic monitoring of information about the usage of system process resources, you can enter the following letters to adjust the display:

F: Locks the function to dynamically display information, so that the usage of system process resources is no longer updated.
T: Unlocks the function to dynamically display information, so that the usage of system process resources is automatically updated. By default, the function to dynamically display information about the usage of system process resources is unlocked.
Q: Exits the process of dynamically displaying the usage of system process resources. You can also press Ctr+C to exit the process. If you do not exit the process, the usage of system process resources keeps being updated.

Implementation Procedure

During the dynamic display of CPU usage, you can enter the following characters to adjust the command output:

f: Dynamic entries are locked and CPU usage is no longer updated.
t: Dynamic entries are unlocked and CPU usage is updated dynamically. By default, CPU usage is updated dynamically.
q: Quits the dynamic display of CPU usage. Alternatively, you can press Ctrl+C. If q is not entered, CPU usage is updated dynamically.

Precautions

A user logging in to a device using the console interface cannot use the monitor cpu-usage command to dynamically display CPU usage.
During the dynamic display of CPU usage, other commands cannot be run.
Dynamic CPU usage is displayed at a fixed place on the screen, and historical information is displayed on the top of the screen.
Due to deviations in the interval (at which CPU usage is collected) and the calculation (based on which CPU usage is obtained), and the cost of user task switching, the obtained CPU usage may differ from the actual value. A system task can have a maximum of 10 user tasks and the error of CPU usage of the user task is +-5%.
The device to which you log in through the console port does not support the function to dynamically display the usage of system process resources.
During the process of dynamically displaying the usage of system process resources, other commands cannot be executed.
After the command is executed, information about the usage of system process resources is displayed in real time on the screen, with historical usage information being reserved.

In VS mode, this command is supported only by the admin VS.
