Compiler Collection  bpftrace high-level tracing language for eBPF ## Performance Co-Pilot Toolkit for collecting, analyzing

applications and useful insights to troubleshoot system performance problems. Projects such as BCC, bpftrace, Hubble, Parca, or Pyroscope use eBPF for tracing and monitoring purposes. The team flew and traveled
