## Amazon CloudWatch Metrics

* **Note**\
  Lambda Function Metrics are emitted for Task states that specify the Lambda function ARN in the `Resource` field. Task states that use `"Resource": "arn:aws:states:::lambda:invoke"` emit Service Integration Metrics instead. For more information, see [Invoke Lambda with Step Functions](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_step_functions/connect-lambda.md).

## Logging using CloudWatch Logs

* **Note**\
  When you configure logging, [CloudWatch Logs charges](http://aws.amazon.com/cloudwatch/pricing) will apply.
