5 Enabling and disabling management module CPU usage calculations Enabling and disabling management module CPU usage calculations You can enable the router to perform usage averaging calculations on tasks handled by CPU on the management module. You can then display usage averages for all tasks performed by the CPU on the management module for an interval of up to one hour. You can display these statistics using the show cpu command. NOTE Typically, these statistics are used for debugging purposes. By default, the performance of the calculations is disabled. When disabled, you can use the show cpu command without optional parameters to display usage averages for all tasks performed by CPU on the management module. NOTE The cpu-usage command must be configured in order to poll the MP CPU utilization. To enable the usage averaging calculations, enter the following command at the global CONFIG level of the CLI. PowerConnect(config)# cpu-usage on Syntax: cpu-usage on To disable the usage averaging calculations, enter the following command at the global CONFIG level of the CLI. PowerConnect(config)# cpu-usage off Syntax: cpu-usage off NOTE When you are finished gathering statistics for debugging purposes, it is recommended that you disable the usage averaging calculations, which are CPU-intensive and can affect the performance of the management module. Displaying CPU usage Use the show cpu command to display usage averages for all tasks performed by the management module as shown in this example. PowerConnect# show cpu ...
