Linux has been adding tracing technologies over the years: kprobes (kernel dynamic tracing), uprobes (user-level dynamic tracing), tracepoints (static tracing), and perf_events (profiling and hardware counters). They use third-party software like Docker or Kubernetes to simplify their administration. People rarely create them manually.
