display cpu-usage history
Use display cpu-usage history to display the historical CPU usage statistics in a coordinate system.
Syntax
display cpu-usage history [ job job-id ]
Views
Any view
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.
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.

Parameters
ratio: Specifies free-memory thresholds in percentage. If you do not specify this keyword, the command sets free-memory thresholds in MB.
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.
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.
You can use the display memory command to display memory usage information.
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
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.
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.

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 period is fixed at 24 hours for a severe alarm and is fixed at 7 * 24 hours for a minor alarm.
Examples
# Enable resending of minor resource depletion alarms.
<Sysname> system-view
[Sysname] resource-monitor minor resend enable

Default

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 vlaue of 0 inidcates 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
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.

Parameters
slot slot-number: Specifies the slot number of the device, which is fixed at 1.
hotspot: Configures temperature alarm thresholds for hotspot sensors. A hotspot sensor is typically near the chip that generates a great amount of heat and used to monitor the chip.
sensor-number: Specifies a sensor by its number. To view the value range, enter a question mark (?) in the place of this argument.
lowlimit: Specifies the low-temperature threshold in Celsius degrees. The value range varies by temperature sensor. To view the value range, enter a question mark (?) in the place of this argument.
warninglimit: Specifies the high-temperature warning threshold in Celsius degrees. This threshold must be greater than the low-temperature threshold. To view the value range, enter a question mark (?) in the place of this argument.
alarmlimit: Specifies the high-temperature alarming threshold in Celsius degrees. This threshold must be greater than the warning threshold. To view the value range, enter a question mark (?) in the place of this argument.
Usage guidelines
When the device temperature drops below the low-temperature threshold or reaches the high-temperature warning or alarming threshold, the device performs the following operations:
· Sends log messages and traps.
· Sets LEDs on the device panel.
Examples
# Set temperature alarm thresholds for hotspot sensor 1 in a slot.
