How to extract env OTEL_RESOURCE_ATTRIBUTS from pod when using redisreceiver

[sswieton]

Hi,

My environment is deployed on Kubernetes.
Version : Chart Helm opentelemetry-collector-0.111.1 app Version : 0.115.1

I would like to collect metrics from a Redis database and enrich the labels using environment variables defined in the Redis containers.
In the Redis containers, the env OTEL_RESOURCE_ATTRIBUTES="myenv=redis" is defined

My configuration is as follows:

I am using the Redis receiver

receivers:
    redis:
      endpoint: "redis-otlp-tcp:6379"
      collection_interval: 10s
      password: pwd
      username: user

In the processors, I use the environment and system detectors.

    resourcedetection:
      detectors: [env,system]
      timeout: 2s
      override: false

My pipeline

    pipelines:
      metrics:
        receivers:
          - redis
        processors:
          - resourcedetection
          - batch
        exporters: 
          - debug/verbose

Issues

In the Resource Attributes, I can only get information related to the system, not the env
Maybe my configuration is incorrect or incomplete

Thanks for your support
