Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH ユーザーズマニュアル

Monitoring CPU Utilization

You can monitor the CPU utilization and history for all of the processes running on the switch. 
By viewing this history on a regular basis, you can see trends emerging and identify 
processes with peak utilization. Monitoring the workload of the CPU allows you to 
troubleshoot and identify suspect processes before they become a problem. By default, the 
switch monitors CPU utilization every 5 seconds. In addition, when CPU utilization of a 
process exceeds 90% of the regular operating basis, the switch logs an error message 
specifying the process name and the current CPU utilization for the process. 

Disabling CPU Monitoring

To disable CPU monitoring, use the following command:

disable cpu-monitoring

This command disables CPU monitoring on the switch; however, it does not clear the 
monitoring interval. Therefore, if you altered the monitoring interval, this command does not 
return the monitoring interval to 5 seconds. The next time you enable CPU monitoring, the 
switch uses the existing configured interval.

Enabling CPU Monitoring

To enable CPU monitoring, use the following command:

enable cpu-monitoring {interval <seconds>} {threshold <percent>}

Where the following is true:

seconds

—Specifies the monitoring interval. The default interval is 5 seconds, and the 

range is 5 to 60 seconds. NETGEAR recommends the default setting for most network 
environments. 

threshold

—Specifies the CPU threshold value. CPU usage is measured in percentages. 

The default is 90%, and the range is 0% to 100%.

By default, CPU monitoring is enabled and occurs every 5 seconds. The default CPU 
threshold value is 90%. 

Displaying CPU Utilization History

To display the CPU utilization history of one or more processes, use the following command:

show cpu-monitoring {process <name>} {slot <slotid>}

Where the following is true:

name

—Specifies the name of the process.
