Profiling with firepit#3333
Conversation
OTel collector added for profiling with highenend privileges. Send the profiling data to a pyroscope backend. Makefile updated with start-profiling target which starts the demo along with the profiling collector.
Firepit is a opensource tool to view profiles in a flame graph, it doesn't store the profiles. https://github.com/florianl/firepit/tree/main

Can we utilize collector as a gateway for profiling as for any other signals? |
This shows how you can use the main collector as a gateway for all otel signals
Good shout, we can indeed do this. I have updated the PR. We now send the profiling signal from the ebpf collector to the main collector. |

@florianl and @osullivandonal it would be nice to have that in: florianl/firepit#17 I've played locally and with that change we can add Firepit to Envoy and reach it via |

I assume here we need to update docs, what is the thoughts here? Should we update the opentelemtry.io demo docs? |

Nice addition! Profiling is a great signal to have in the demo, and the eBPF collector + Firepit approach keeps things lightweight.
