Python: trace to profile

[mtotone]

Hello,

I have set up a stack with Grafana/Prometheus/Loki/Tempo/Alloy/Pyroscope on Kubernetes.

My applications are successfully sending:

• traces to Alloy using otelcol.receiver.otlp
• profiles using Pyroscope

I can see them in the new Drilldown tab.

In the attributes of my traces, I can see pyroscope.profile.id. However, when I click on the "Profiles for this span" button, I don’t get any flamegraphs.
If I remove the spanID, the flamegraphs do show up.
This makes me think that my profiles don’t actually contain the spanID.

I tested using the example code here: https://github.com/grafana/pyroscope/tree/main/examples/tracing/python

I also tried to send profiles to Alloy by adding pyroscope.receive_http.

I am using the latest versions of all components.

Did I miss something ?

Thanks for your help !
