[tempo-distributed] metricsGenerator in helm doesn't populate required configuration in tempo configmap

[raghuafero]

Problem Statement: Trying to enable metrics generator in tempo for grafana APM feature ( using tempo-distributed helm chart"

What has been tried: metricsGenerator: enabled: true config: storage: path: /var/tempo/generator_wal remote_write:

• name: Prometheus send_exemplars: true # whether you want to send exemplars as well url: http://kube-prometheus-stack-prometheus.prometheus:9090/api/v1/write Expected Result: metrics generator enabled and working

Actual Result: only "metrics_generator_enabled: true" is seen in the tempo-distributed configmap

I think this has improved in terms of the resulting tempo-distributed-config configmap, but in my very recent experience, the following is also missing even if you do enable the metrics generator:

    overrides:
      metrics_generator_processors:
      - service-graphs
      - span-metrics

Once you have that in place, I think you'll likely see the metrics being generated as expected. I've been chatting with @joe-elliott about this and seems like a good candidate for a PR. Just working through some of the details with him as this would be my first contribution to this repo.

I think it was done after a fix of issue
