Use of OpenTelemetry Dashboard(https://www.dynatrace.com/hub/detail/opentelemetry-dashboards/)

[EvaThms]

Hi,

I added the dashboard (https://www.dynatrace.com/hub/detail/opentelemetry-dashboards/) from your hub to my Dynatrace environment, to monitor my opentelemetry collector. But this dashboard is expecting metrics like otelcol_receiver_accepted_spans and what I am getting from the basic configuration that is given in the documentation is metrics like otelcol_receiver_accepted_spans.count. I have this ".count" on all metrics required by the dashboard and so the dashboard is empty. I tried everything to get those metrics in the correct format but I can't make it work. Can you tell me what I'm doing wrong ?

I followed the documentation and I don't have anything special in my configuration.

my config :

telemetry:

        metrics:

          level: detailed

          readers:

            - periodic:

                interval: 60000

                exporter:

                  otlp:

                    protocol: http/protobuf

                    temporality_preference: delta

                    endpoint: "${env:DT_ENDPOINT}/v1/metrics"

                    headers:

                      - name: Authorization

                        value: "Api-Token ${env:DT_API_TOKEN}"

Thanks in advance for your help,

Eva

Sorry the dashboard I'm trying to use is : OpenTelemetry Collector self-monitoring — Dynatrace Docs

J'utilise l'image opentelemetry-collector-contrib:0.144.0, est-ce que le problème vient d'une incompatibilité avec l'image contrib ?
