Context information

AWS service: ApiGateway CloudWatch namespace: AWS/ApiGateway Metrics documentation for this service: cloudwatch cli: aws cloudwatch list-metrics --namespace AWS/ApiGateway

Attempted Exporter configuration 1

    - aws_namespace: AWS/ApiGateway
      aws_metric_name: 4xx
      aws_dimensions: [ApiId]
    - aws_namespace: AWS/ApiGateway
      aws_metric_name: 5xx
      aws_dimensions: [ApiId]    

Attempted Exporter configuration 2

    - aws_namespace: AWS/ApiGateway
      aws_metric_name: 4xx
      aws_dimensions: [Stage,ApiId]
    - aws_namespace: AWS/ApiGateway
      aws_metric_name: 5xx
      aws_dimensions: [Stage,ApiId]    

Working Exporter configuration for comparison

  - aws_namespace: AWS/ApiGateway
    aws_metric_name: Count
    aws_dimensions: [ApiId]

What do you expect to happen?

Cloudwatch '4xx' and '5xx' metrics to be exported.

What happened instead?

Both '4xx' and '5xx' metrics were not exported or recognized.

For comparison I have included a ApitGateway metric that was successfully exported using the config from the same documentation source; aws cloudwatch list-metrics --namespace AWS/ApiGateway

There were two metric configs listed for '4xx' and '5xx' respectively. Both were attempted and both have been included above.

Please use 4XXError and 5XXError as shown in the example: https://github.com/prometheus/cloudwatch_exporter/blob/master/examples/ApiGateway.yml

Referencing the documentation above, the below has failed to pull metrics through.

Config Used

  - aws_namespace: AWS/ApiGateway
    aws_metric_name: 4XXError
    aws_dimensions: [Stage,ApiName]
  - aws_namespace: AWS/ApiGateway
    aws_metric_name: 5XXError
    aws_dimensions: [Stage,ApiName]

It seems from the documentation that Stage requires detailed metrics. What happens when you remove it from aws_dimensions?

What is the output of aws cloudwatch list-metrics --namespace AWS/ApiGateway for you?
