syscalldist is the tool to profile syscalls.
# git clone https://github.com/Asphaltt/syscalldist.git
# cd syscalldist
# go generate && go build
# ./syscalldist -h
Usage of ./syscalldist:
--kernel-btf string kernel BTF file
-l, --list-syscall list syscalls of amd64 Linux used by Go syscall
--pid uint32 filter pid
--syscall uint32 filter syscall id
--syscall-name string filter syscall name
