network-operator
Parameters
job job-id: Specifies a process by its ID. The value range for job-id is 1 to 2147483647. If you do not specify a process, this command displays the statistics for the entire system's CPU usage (the total CPU usage of all processes). To view the IDs and names of the running processes, use the display process command. For more information, see Network Management and Monitoring Command Reference.
slot slot-number: Specifies a cloud cluster member device by its member ID. If you specify a process but do not specify a member device, this command displays the statistics for the process on the master device. If you do not specify any options, this command displays the statistics for all processes on all member devices.
cpu cpu-number: Specifies a CPU by its number. If you specify a process but do not specify a CPU, this command displays the statistics for the default CPU. If you do not specify a process or CPU, this command displays the historical statistics for all CPUs.
Usage guidelines
After CPU usage tracking is enabled, the system regularly samples CPU usage and saves the samples to a buffer. This command displays the most recent 60 samples in a coordinate system as follows:
· The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is rounded up or down to the closest multiple of the usage step. For example, if the CPU usage step is 5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded down to 50%.
· The horizontal axis represents the time.
· Pound signs (#) indicate the CPU usage. The value on the vertical axis for the topmost pound sign at a specific time represents the CPU usage at that time.
Examples
# Display the historical CPU usage statistics.

Usage guidelines
To ensure correct operation and improve memory efficiency, the system monitors the amount of free memory space in real time. If the amount of free memory space decreases to or below the minor, severe, or critical alarm threshold, the system issues an alarm to affected service modules or processes.
(On devices that do not support low memory.) You can use the display memory command to display memory usage information.
(On devices that support low memory.) The system monitors only the amount of free low-memory space. You can use the display memory command to display memory usage information.
(On devices with slots that support low memory.) For slots that support low memory, the system monitors only the amount of free low-memory space. You can use the display memory command to display memory usage information. If the LowMem field is displayed for a slot, the slot supports low memory.
The early warning feature warns you of an approaching insufficient-memory condition.
If a memory alarm occurs, delete unused configuration items or disable some features to increase the free memory space. Because the memory space is insufficient, some configuration items might not be able to be deleted.
For more information about the thresholds, see Fundamentals Configuration Guide.
The device will restart if one of the following conditions is met:
· After a critical alarm occurs, the remaining free-memory value has been smaller than the critical alarm threshold for 30 seconds.
· The interval between two consecutive critical alarms is shorter than 30 seconds.
· The critical alarm has occurred three times within three minutes.
· After a critical alarm occurs, the system will periodically sample free memory space and predict if the free memory space will be exhausted within 30 seconds. If the prediction result indicates that the free memory space will be exhausted within 30 seconds, the device will restart.
The sending periods of memory alarm notifications are as follows:
· If the free memory space has consistently exceeded the early-warning threshold for 1 hour, an early-warning alarm notification is sent.
· If the free memory space has consistently exceeded the minor threshold for 12 hours, a minor alarm notification is sent.
· If the free memory space has consistently exceeded the severe threshold for 3 hours, a severe alarm notification is sent.
· If the free memory space has consistently exceeded the critical threshold for 1 hour, a critical alarm notification is sent.

Predefined user roles
network-admin
Parameters
interval: Specifies the port status detection timer value in seconds. The value range is 0 to 300. The value of 0 indicates that port status detection is not automatically performed, and you need to execute the undo shutdown command to restore the port status manually.
Usage guidelines
On a network enabled with loopback detection or STP, the device starts a port status detection timer when a port is shut down by a protocol. If the port has been in down state before the timer expires, the device will set the port status to the port's physical status.
If you change the timer setting during port detection, the device compares the new setting (T1) with the time that elapsed since the port was shut down (T).
If T < T1, the port will be brought up after T1 – T seconds.
If T ≥ T1, the port is brought up immediately.
For example, the timer setting is 30 seconds. If you change it to 10 seconds 2 seconds after the port is shut down, the port will come up 8 seconds later. If you change the timer setting to 2 seconds 10 seconds after the port is shut down, the port comes up immediately.
Examples
# Set the port status detection timer to 100 seconds.

· Sends log messages and traps.
· Sets LEDs on the device panel.
