Sending OpenTelemetry traces from Collector to Prometheus to create RED Dashboards

In your setup, all the Otel instruments' traces are sent to Tempo, and from there, we can "Explore" them from Grafana.

I found difficulties in digesting the info from Tempo to generate Dashboards like this one:

• https://grafana.com/grafana/dashboards/19419-opentelemetry-apm/

I think they are called RED metrics.

I asked the Grafana community, and they explained to me that we have to expose the Otel traces in the Collector to Prometheus (on top of sending them to Tempo) so we can generate metrics dashboards as the suggested.

What are your thoughts about this? Do you think it should be included in your setup?

Why to push the Rails logs to the STDOUT?

promtail is perfectly capable of scraping the logs from my-app/logs/ and is simpler and more intuitive:

  promtail:
    image: grafana/promtail:3.0.0
    volumes:
      - ./docker/promtail/config.yml:/etc/promtail/config.yml
      - ./log/:/var/log/rails/:ro
    command: -config.file=/etc/promtail/config.yml

I am asking because your repo inspires me, and it helped me a lot. I want to know I am not missing anything.

Thanks for your work

Tempo dashboard

I am configuring my architecture observability strongly inspired by this repo.

I want to configure a Tempo dashboard, but I don't know where to start. There are not any usable Tempo dashboards on the Grafana Dashboards page.

In this repo, I see there is one Dashboard, but it is a Prometheus one.

Thanks for your work

Integrate `influxdb-rails` to instrument the Rails app

I am seeing these nice Dashboards specialized in Rails apps:

• https://grafana.com/grafana/dashboards/10428-performance/

With monitors for Jobs, Exceptions, and more

It requires generating metrics with the influxdb-rails that specializes in instrumenting rails apps:

• https://github.com/influxdata/influxdb-rails/tree/master

It requires, of course, an InfluxDB instance.

Do you think this setup adds any value to the setup this project already has?

Or do you think we can achieve the same level of Rails specialized Dashboards with the prometheus-client metrics?
