Unable to Filter Metrics Using Resource Attributes - resource_attributes

[mskhan-devops]

Hi Everyone,
As per the example on page opentelemetry-collector-contrib/processor/filterprocessor, I am trying to configure ADOT Collector Pipeline for EKS cluster to publish metrics to CloudWatch Container Insights:

processors:
  filter/1:
    metrics:
      include:
        match_type: regexp
        metric_names:
          - pod_cpu_.*

This works fine and I see filtered metrics against my apps in the Container Insights.

The problem is as soon as I add resource_attributes to the above configuration to filter out metrics against the specific app running in the EKS cluster, like below:

processors:
  filter/1:
    metrics:
      include:
        match_type: regexp
        metric_names:
          - pod_cpu_.*
        resource_attributes:
          - Key: k8s.pod.name
            Value: myapp-pod-with-hash.*

AWS ADOT Collector stops publishing any metrics to Container Insights. Can anyone please help with this?

I am using this guide and sample config file:
Cost savings by customizing metrics sent by Container Insights in Amazon EKS

Sample config file:
otel-container-insights-infra.yaml

Thanks

Is this a query for opentelemetry-cpp, or opentelemetry-collector?

Can this be moved to the right category?
