[BUG] alb, nlb targetgroup metrics not joinable on name with aws_(alb,nlb)_info metric

[domcyrus]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The metrics emitted by yace for alb and nlb regarding targetgroup metrics e.g. aws_alb_healthy_host_count_minimum are not possible to correlate with the respective aws_(alb,nlb)_info metric. (https://github.com/nerdswords/yet-another-cloudwatch-exporter#query-examples-without-exportedtagsonmetrics)

The problem is that the name label (arn) for the info metric is using the targetgroups ARN while the targetgroup related metric e.g. aws_alb_healthy_host_count_minimum is using the loadbalancers ARN.

aws_alb_healthy_host_count_minimum{name="arn:aws:elasticloadbalancing:eu-west-1:1111:loadbalancer/app/alb-external/asdfasdf"}

aws_alb_info{name="arn:aws:elasticloadbalancing:eu-west-1:1111:targetgroup/asdf-asdf/xasdf", tag_Port="9999"}

This does not work to join with:
(aws_alb_healthy_host_count_minimum + on (name) group_left(tag_Port) aws_alb_info)

Expected Behavior

Being able to join the targetgroup related metrics.

Steps To Reproduce

Use targetgroup related metrics like:

"discovery":
  "jobs":
  - "enableMetricData": true
    "metrics":
    - "length": 300
      "name": "HealthyHostCount"
      "period": 300
      "statistics":
      - "Minimum"
    - "length": 300
      "name": "UnHealthyHostCount"
      "period": 300
      "statistics":
      - "Maximum"
    "regions":
    - "eu-central-1"
    "type": "alb"

Try to join targetgroup related metrics.
