// Indicates whether the specified Config rules are compliant. If a rule is
// noncompliant, this action returns the number of Amazon Web Services resources
// that do not comply with the rule. A rule is compliant if all of the evaluated
// resources comply with it. It is noncompliant if any of these resources do not
// comply. If Config has no current evaluation results for the rule, it returns
// INSUFFICIENT_DATA . This result might indicate one of the following conditions:
//   - 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 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.
