sigwire
tail -f for signals. Every signal any process on the box raises — who sent it, who it hit, which signal, how it was raised (kill(2), the kernel, a POSIX timer), whether the target caught it and how long its handler ran, whether it tore a blocked syscall out with EINTR.
What is it?
What it is
> **`tail -f` for signals.** Every signal any process on the box raises — who sent it, who it hit, which signal, how it was raised (`kill(2)`, the kernel, a POSIX timer), whether the target caught it and how long its handler ran, whether it tore a blocked syscall out with `EINTR` — decoded off the kernel's signal tracepoints and streamed live to your terminal. No `strace -f` on one pid, no `ptrace`, no cooperation from the processes involved.
Why it exists
tail -f for signals. Every signal any process on the box raises — who sent it, who it hit, which signal, how it was raised (kill(2), the kernel, a POSIX timer), whether the target caught it and how long its handler ran, whether it tore a blocked syscall out with EINTR.
