more capable, and built from the ground up for the modern era of the eBPF virtual machine. Syscall count by program bpftrace -e 'tracepoint:raw_syscalls:sys_enter { @[comm] = count(); }'. bcc is powerful but laborious to program. It's shaping up to be a DTrace version 2.0: Might bpftrace SIGSEGV and coredump? eBPF does more.
