CPU usage statistics reported for Control and Analysis planes are not always allocated appropriately between the two planes.


CPU usage statistics for Control and Analysis planes may not provide actionable data due to their inaccuracy.


Non-Data plane processes consuming CPU cycles generate usage statistics that are then classified as Control or Analysis plane CPU usage.
