--
-- Indicates whether the specified AWS resources are compliant. If a
-- resource is noncompliant, this action returns the number of AWS Config
-- rules that the resource does not comply with.
--
-- A resource is compliant if it complies with all the AWS Config rules
-- that evaluate it. It is noncompliant if it does not comply with one or
-- more of these rules.
--
-- If AWS Config has no current evaluation results for the resource, it
-- returns 'InsufficientData'. This result might indicate one of the
-- following conditions about the rules that evaluate the resource:
--
-- -   AWS Config has never invoked an evaluation for the rule. To check
--     whether it has, use the 'DescribeConfigRuleEvaluationStatus' action
--     to get the 'LastSuccessfulInvocationTime' and
--     'LastFailedInvocationTime'.
-- -   The rule\'s AWS Lambda function is failing to send evaluation
--     results to AWS Config. Verify that the role that you assigned to
--     your configuration recorder includes the 'config:PutEvaluations'
--     permission. If the rule is a customer managed rule, verify that the
--     AWS Lambda execution role includes the 'config:PutEvaluations'
--     permission.
-- -   The rule\'s AWS Lambda function has returned 'NOT_APPLICABLE' for
--     all evaluation results. This can occur if the resources were deleted
--     or removed from the rule\'s scope.
