Profiling for specific process by labels, not all node processes

[lingpeng0314]

I am not sure if this feature is reasonable for this project, may be more proper when migrate this profiler into openTelemetry collector as profiling agent.

We plan to adopt continuous profiling for internal use. And the common use case is to select some specific pods to obtain profiling data instead of all kinds of processes in K8s node.

Invested several agents like Grafana Alloy/Parca/Pixie, all of them support the feature that only profiling specific pods. And as we move eBPF profiler into collector as agent, this should be a very reasonable requirement right?

As a sampling based profiler, eBPF profiler is designed and architected to profile the whole system. Filtering, e.g. on a label, can be applied on post processing stages, the backend or UI.
With the ongoing integration into OTel collector, more processors/filters should become available.

Look forward to the integration into OTel collector very much.

@florianl Do we have roadmap for when integrate the profiler into OTel collector?
