Applicable Environment
The CPU and memory are key parts of a device. Routing information and fast route algorithms
can consume a large amount of CPU resources, affecting system performance. If resource usage
is too great, the device is unable to process data in a timely manner, packets may be lost, or the
system may break down. Customers must bear the losses from such occurrences.
If alarms warn of high CPU or memory usage during data processing on the router, CPU and
memory usage can be effectively monitored, and the system performance can be optimized. This
facilitates normal system operations.
Pre-configuration Tasks
Before setting CPU and memory usage thresholds, complete the following task:
l Making sure that the router is working properly
Data Preparation
To set CPU and memory usage thresholds, you need the following data.
No. Data
1 CPU usage thresholds, including an alarm threshold and a clear alarm threshold
2 Memory usage threshold
9.5.2 Setting CPU Usage Thresholds
Setting CPU usage thresholds allows CPU usage to be monitored.
Context
Two CPU usage thresholds are set:
l Alarm threshold: indicates that the system generates an alarm when CPU usage reaches
this alarm threshold.
l Clear alarm threshold: indicates that the alarm is cleared when CPU usage falls below this
clear alarm threshold.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
set cpu-usage threshold threshold-value [ restore restore-threshold-value ] [ slot
slot-id ]
An alarm threshold and a clear alarm threshold are set for CPU usage on an MPU or an LPU in
a specified slot.
