Enabling and disabling management module CPU usage
calculations
You can enable the BigIron RX Series system to perform usage averaging calculations on tasks
handled by the management module’s CPU. If you enable the calculation performance, you can
display usage averages for all tasks performed by the management module’s CPU for an interval of
up to 1 hour. You can display these statistics using the show cpu command. 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
the management module’s CPU in the last 1 second.
To enable the performance of the usage averaging calculations, enter the following command at
the global CONFIG level of the CLI:
BigIron RX(config)# cpu-usage on
Syntax: cpu-usage on
To disable the performance of the usage averaging calculations, enter the following command at
the global CONFIG level of the CLI:
BigIron RX(config)# cpu-usage off
Syntax: cpu-usage off
NOTE
When finished gathering statistics for debugging purposes, Brocade recommends disabling the
usage averaging calculations, which are CPU-intensive and can affect the performance of the
management module.
