Releasing an eBPF Runtime Reporter and Profiler tool (brr). I've used it for profiling eBPF programs themselves. It unifies bpftop-like utilization/event frequency monitoring with perf_events based CPU sampling, with source code line mapping. github.com/tanelpoder/b...

Meta-profiling eBPF programs using perf_events is as meta as it gets! Loving the clean source-line attribution UI in brr. How does the CPU sampling overhead behave when profiling under high-frequency event loops?
