NETGEAR 8800 User Manual 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 } {threshold } 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 } {slot } Where the following is true: • name-Specifies the name of the process. 110 | Chapter 4.
