display cpu-usage history
Format
display cpu-usage history [ 1hour | 24hour | 72hour ] [ slave | slot slot-id ] [ vcpu vcpu-index ]
The slave parameter is not supported if the switch does not support the stacking function or does not have the stacking function enabled.
Only the S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support the vcpu vcpu-index parameter.
Parameters
| Parameter | Description | Value |
|---|---|---|
1hour |
Displays CPU usage statistics within the last one hour. |
- |
24hour |
Displays CPU usage statistics within the last 24 hours. |
- |
72hour |
Displays CPU usage statistics within the last 72 hours. |
- |
slave |
Displays the CPU usage statistics of slave devices in a stack. This parameter is valid only in a stack system. |
- |
slot slot-id |
Displays the CPU usage statistics of a specified slot ID. |
The value varies with the device configuration. |
vcpu vcpu-index |
Displays the CPU usage statistics of a specified virtual CPU. |
Specify the vcpu-index parameter based on the hardware configuration. |
Usage Guidelines
Usage Scenario
The system collects CPU usage statistics at a specified interval (usually 60s) and saves them in the historical record table. To check CPU usage statistics within a period, run the display cpu-usage history command, and the command output helps you determine whether the CPU is working properly.
In the display cpu-usage history command output, the x-coordinate indicates the specified period, and the y-coordinate indicates the CPU usage.
Precautions
If CPU usage is constantly higher than the upper alarm threshold (95% by default) before the feature is deployed on a large scale, check the device to troubleshoot the fault.

Item |
Description |
|---|---|
System cpu-usage last 60 minutes(Per Min) |
CPU usage statistics within the last one hour, with a step of one minute. |
System cpu-usage last 24 hours(Per Halfhour) |
CPU usage statistics within the last 24 hours, with a step of half an hour. |
System cpu-usage last 72 hours(Per Hour) |
CPU usage statistics within the last 72 hours, with a step of an hour. |
* = maximum cpu-usage |
Maximum CPU usage. For example, the maximum CPU usage in the first hour in the latest 72 hours is 75%. |
H = average cpu-usage |
Average CPU usage. For example, the average CPU usage in the first hour in the latest 72 hours is 5%. |
