[bug]: Not able to fetch metrics when tagging enabled.

[shubhadaR]

we tried to use AWS tag select feature However we only got aws_resource_info with tags but not aws resource metric.

config.yaml

region: ap-south-1
delay_seconds: 10
use_get_metric_data: false
metrics:
- aws_namespace: AWS/ELB
   use_get_metric_data: false
   aws_metric_name: RequestCount
   aws_dimensions: [AvailabilityZone, LoadBalancerName]
   aws_tag_select:
     tag_selections:
       Monitoring: ["enabled"]
     resource_type_selection: "elasticloadbalancing:loadbalancer"
     resource_id_dimension: LoadBalancerName
   aws_statistics: [Sum]
- aws_namespace: AWS/ELB
   use_get_metric_data: false
   aws_metric_name: RequestCount
   aws_dimensions: [AvailabilityZone, LoadBalancerName]
   aws_statistics: [Sum]

I believe I'm seeing similar issue with apigateway.

config:

metrics:
  - aws_namespace: AWS/ApiGateway
    aws_metric_name: 5XX
    aws_statistics: [Sum]
    aws_dimensions: [ApiId]
    aws_tag_select:
      tag_selections:
        Product: ["ABC"]
      resource_type_selection: "apigateway:apis"
      resource_id_dimension: ApiId

Then only aws_resource_info metric is returned. But that metric seems to have incorrect api_id label.
Because it does not have only api gateway Id as value, but also apis prefix:

aws_resource_info{job="aws_apigateway",instance="",arn="arn:aws:apigateway:us-east-1::/apis/XXX",api_id="apis/XXX",tag_Product="ABC"} 1.0

@shubhadaR take a look here.

Interesting, so we've started getting prefixes in the ID dimension during tag selection, but the would need to strip them out when fetching the metrics?

[matthiasr]

#571 has an explanation how to work around this. #648 is also related to the tag format issues, although I don't fully understand whether it will address the need for the workaround.

@matthiasr i think this issue can be closed, because seems to be a configuration understanding.
