// Indicates whether the specified Amazon Web Services resources are compliant. If
// a resource is noncompliant, this action returns the number of Config rules that
// the resource does not comply with. A resource is compliant if it complies with
// all the Config rules that evaluate it. It is noncompliant if it does not comply
// with one or more of these rules. If Config has no current evaluation results for
// the resource, it returns INSUFFICIENT_DATA . This result might indicate one of
// the following conditions about the rules that evaluate the resource:
//   - 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 Lambda function is failing to send evaluation results to Config.
//     Verify that the role that you assigned to your configuration recorder includes
//     the config:PutEvaluations permission. If the rule is a custom rule, verify
//     that the Lambda execution role includes the config:PutEvaluations permission.
//   - The rule's 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.
