Provides a live, kernel-tracepoint-based view of every signal on a Linux system, showing who sent it, who received it, whether it was caught, and if it interrupted a syscall—all without per-process tracing or overhead.

Description

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.
