      * ``ENFORCE`` - The policy engine evaluates actions against your policies and enforces decisions by allowing or denying agent operations. Test and validate policies in ``LOG_ONLY`` mode before enabling enforcement to avoid unintended denials or adversely affecting production traffic.
      

      

    
  
  :type exceptionLevel: string
  :param exceptionLevel: 

    The level of detail in error messages returned when invoking the gateway.

          * ``ENFORCE`` - The policy engine evaluates actions against your policies and enforces decisions by allowing or denying agent operations. Test and validate policies in ``LOG_ONLY`` mode before enabling enforcement to avoid unintended denials or adversely affecting production traffic.
