parca-agent

Parca Agent is an always-on sampling profiler that uses eBPF to capture raw
profiling data with very low overhead. It observes user-space and
kernel-space stacktraces 100 times per second and builds pprof formatted
profiles from the extracted data.

The collected data can be viewed locally via HTTP endpoints and then be
configured to be sent to a Parca server to be queried and analyzed over time.
