Backends able to receive OTLP profile signals

[christophe-kamphaus-jemmic]

Which backends are able to receive the OTLP profile signals?

I know that the opentelemetry-collector is able to receive it, but where can it forward it for storage and analysis?

I have been able to forward it to Grafana Pyroscope.

Although I have not had much luck with getting Python symbols.

Currently I have a Debian Bookworm application container running many Python services, among other things.
This is running on an Azure VM with Docker Enginer.
Alongside the application container I have an OTEL Collector (Contrib) container. That OTEL Collector then also exports to the OTLP endpoint for Pyroscope (default port 4040). Pyroscope can be queried from Grafana itself.

Does the eBpf profile agent needs to run on the same host as the otel collector which is grpc otlp profile signal server for the agent? How can I configure network interface/ip and port for the agent or which other options I have?

can elasticsearch receive the OTLP profile signal from otel collector ?

can elasticsearch receive the OTLP profile signal from otel collector ?

Not yet, no. But we are working on profiles support for the elasticsearch collector exporter.

opentelemetry-ebpf-profiler needs to run on the host which should be observed, while the opentelemetry-collector / profiling backend able to receive the OTLP signals can run on another host.

How can I configure network interface/ip and port for the agent or which other options I have?

This issue also mentions it: #285

Thanks

Since I posted this issue I have also come across https://github.com/metrico/qryn which claims to be able to ingest Opentelemetry profiling signals and being compatible with Pyroscope API (so usable from Grafana). I haven't tried it yet though.
