Are you managing your controller from the controller UI or from the AirWave UI?
If you're managing from the controller UI, then you'll want to run audit and then import (to import the settings of the controller to the group the controller exists in AirWave) occasionally to sync the AirWave desired config to the current running config. (assuming that in AirWave, the controller's manage page has management setting set for monitor only mode). Be careful if you have multiple controllers in the same group, especially if each controller has a different config (controllers should be grouped by configuration -> otherwise specific controller overrides need to be maintained on the controller's manage page under overrides).
If you're managing from AirWave, then you just need to perform the changes from the AirWave UI and they will be pushed to the controller when a mismatch is observed after audit.
AMP setup has a general audit interval setting, but each group has a toggle that enables/disables auditing on the Group -> select group -> Basic tab.
