Depending on the version & configuration, there exist both kernel tracepoints and kprobe/jprobe sites where the kernel side of these events may be hooked. You may be able to attach to each of those from userspace via perf. For comparison, systemtap chooses whatever facility is available in your kernel, by internally mapping the abstract "signal.send" name into a list of candidates. # stap -e ' probe signal.send { if (sig_name == "SIGKILL") printf("%s was sent to %s (pid:%d) by %s uid:%d\n", sig_name, pid_name, sig_pid, execname(), uid()) }' - FChE
