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.
