I am new to all this architecture, and I am a bit lost.

I have integrated all these instruments in my Rails application:

gem "opentelemetry-exporter-otlp"
gem "opentelemetry-instrumentation-mysql2"
gem "opentelemetry-instrumentation-net_http"
gem "opentelemetry-instrumentation-rack"
gem "opentelemetry-instrumentation-rails"

I am sending the metrics to an instance of OpenTelemetryCollector, and from there to a Tempo instance.

In Grafana, I have configured the Tempo datasource.

I can see the Traces in the Grafana > Explorer:

But I don’t know how to build a proper dashboard with it. I have tried to import a dashboard like this. But the data source is Prometheus, not Loki. The are only 2 dashboards for Tempo on this database. And they don’t look like the one I want.

I would like to see the requests, the statuses, the request_time, … as in the OpenTelemetry APM Dashboard

Any help?

If my architecture is wrong, I am also willing to change it.
