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.

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.
early-warning early-warning-value: Specifies the early-warning threshold. To view the value range for this threshold, enter a question mark (?) in the place of the early-warning-value argument. Setting this threshold to 0 disables the early warning feature. The default value for this threshold depends on the device model.
secure secure-value: Specifies the sufficient-memory threshold. To view the value range for this threshold, enter a question mark (?) in the place of the secure-value argument. The default value for this threshold depends on the device model.
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.
(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 system will restart a card 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 system will restart the card.
Once the free memory space reaches the early warning, minor, severe, or critical alarm threshold, the device will display the current memory usage information when you log in to the device through console or Telnet login, or execute every command.
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.

Parameters
slot slot-number: Specifies a card by its slot number. If you do not specify a card, the command applies to the active MPU.
disk disk-name: Specifies a disk by its name. This option is case sensitive. The system will prompt a parameter error if you enter this option incorrectly.
threshold threshold-value: Specifies the disk usage threshold in percentage, in the range of 1 to 100.
Usage guidelines
After you set the disk usage threshold, the device compares the usage of the disk with the threshold at each sampling. If the usage exceeds the threshold, the device sends a high disk usage alarm to the NETCONF module. For more information about the NETCONF module see Network Management and Monitoring Configuration Guide.

Usage guidelines
When a resource type enters minor alarm state, the device issues a minor alarm. If the resource type stays in minor alarm state or changes from severe alarm state to minor alarm state, the device identifies whether resending of minor resource depletion alarms is enabled. If the feature is disabled, the device does not issue additional minor alarms. If the feature is enabled, the device resends minor alarms periodically.
The resending interval of severe alarms is 24 hours and the resending interval of minor alarms is 7×24 hours.
Examples
# Enable resending of minor resource depletion alarms.
<Sysname> system-view
[Sysname] resource-monitor minor resend enable

slot slot-number: Specifies a card by its slot number.
cpu cpu-number: Specifies a CPU by its number.
by-percent: Specifies resource depletion thresholds in percentage.
minor-threshold minor-threshold: Specifies the minor resource depletion threshold. To view the value range, enter a question mark (?) in the place of the minor-threshold argument.
severe-threshold severe-threshold: Specifies the severe resource depletion threshold. To view the value range, enter a question mark (?) in the place of the severe-threshold argument.
Usage guidelines
After you execute this command for a resource type, the device monitors the available amount of the type of resources. The device samples the available amount at intervals, compares the sample with the resource depletion thresholds to identify the resource depletion status, and sends alarms as configured.
Examples
# Set the minor resource depletion threshold to 30% and the severe resource depletion threshold to 10% for ARP entry resources on slot 1.

Views
System view
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 loop 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.
<Sysname> system-view
[Sysname] shutdown-interval 100
