This release of Parca Agent marks a huge milestone! From now on, Parca-Agent, the previously only fully open source, Apache2 licensed, and open for contributions eBPF-based profiler is now based on the opentelemetry-ebpf-profiler, and all language support efforts will be focused there. By basing the Parca-Agent on the opentelemetry-ebpf-profiler besides the C, C++, Rust, Go, Python, and Ruby support, it gained JVM, .NET, Perl, and PHP support! However, on top of the opentelemetry-ebpf-profiler the Parca Agent continues to ship a deep end-to-end integration with the Parca server, delivering the only fully open-source end-to-end system-wide profiling experience.
As such it ships several things on top:
- Allow the Parca server to asynchronously symbolized stacktraces. This means not only interpreted languages have function names, but C, C++, Rust, Go, etc. as well.
- A more optimized wire-protocol based on Apache Arrow. Less CPU time spent putting together the data to send off to the server and less bytes!
- A wide array of metadata from Kubernetes, containerd, cgroups, lxc, docker, etc. so you can make profiling adapt to how you organize your data!
And more!
To use the v0.32.0 release, a Parca server v0.22.0+ is required due to the new wire protocol. Try it out right away via the Quickstart!
Happy Profiling!
