Predefined user roles
network-admin
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 card by its slot number. If you specify a process but do not specify a card, this command displays the statistics for the process on the active MPU. If you do not specify any options, this command displays the statistics for all processes on all cards.
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.

minor minor-value: Specifies the minor alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the minor-value argument. Setting this threshold to 0 disables the minor alarm feature.
severe severe-value: Specifies the severe alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the severe-value argument. Setting this threshold to 0 disables the severe alarm feature.
critical critical-value: Specifies the critical alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the critical-value argument. Setting this threshold to 0 disables the critical alarm feature.
normal normal-value: Specifies the normal state threshold. To view the value range for this threshold, enter a question mark (?) in the place of the normal-value argument.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command sets free-memory thresholds for the active MPU.
cpu cpu-number: Specifies a CPU by its number.
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.
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.

Parameters
severe-threshold: Specifies the severe CPU usage alarm threshold in percentage. The value range for this argument is 2 to 100.
minor-threshold minor-threshold: Specifies the minor CPU usage alarm threshold in percentage. The value range for this argument is 1 to the severe CPU usage alarm threshold minus 1.

Parameters
minor-interval minor-interval: Specifies the minor CPU usage alarm resending interval in seconds, a multiple of 5 in the range of 10 to 3600.
severe-interval severe-interval: Specifies the severe CPU usage alarm resending interval in seconds, a multiple of 5 in the range of 10 to 3600.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command sets the interval for the active MPU.
cpu cpu-number: Specifies a CPU by its number.
Usage guidelines
The device samples CPU usage at intervals, and compares the samples with CPU usage thresholds to identify the CPU usage status and send alarms or notifications accordingly.
In minor alarm state, the device sends minor alarms periodically until the CPU usage increases above the severe threshold or the minor alarm is removed. In severe alarm state, the device sends severe alarms periodically until the severe alarm is removed. This command sets the alarm resending intervals.
If you do not specify a keyword for the undo monitor resend cpu-usage command, the command restores the default minor and severe CPU usage alarm resending intervals.
Examples
# Set the minor CPU usage alarm resending interval to 60 seconds for a slot.

Predefined user roles
network-admin
Parameters
interval: Specifies the port status detection timer value in seconds. The value range is 0 to 300. The vlaue of 0 inidcates that port status detection is not automatically performed. You need to execute the undo shutdown command to restore the port status manually.
Usage guidelines
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.
<Sysname> system-view
[Sysname] shutdown-interval 100
