in the kernel, eBPF enables broad system observability. Collection and in-kernel aggregation of metrics allows flexible and efficient generation of observability events and data structures from a wide range 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, becoming
