I've been using bpftrace -lv to examine available trace points. But the bpftrace output won't show you the complex types definitions and this tool can do it. Great work!
Very handy tool! I love eBPF, but playing with it you quickly get into cryptic kernel internals territory. Tools like this are a great way to smooth out the experience. Well done!
Definitely agree. As I've looked into instrumentation/tracing, it has helped me more fearlessly look at the kernel. Ftrace is another tool that's helped me level up as well (https://blog.px.dev/ebpf-probes-and-you/)
Yeah, ftrace is great and the trace-cmd frontend too. Another swiss-army-knife type of a tool, like perf... and is also available in older kernels.
One thing that I had missed was function call argument tracing, but looks like ftrace will soon have it too (update: it's actually available on modern kernels already, look for CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS kernel config option).
