Cong Wang commented on MESOS-2834:
----------------------------------
Why the kernel version matters here? Doesn't the `perf stat` output format only
depend on perf itself? I know usually they match, but what if people use a
newer perf on an older kernel (or vice versa)?
Ideally we should use perf_event_open(2) rather than parsing perf output which
isn't ABI at all, in practice the ring buffer is not easy to parse.
> Support different perf output formats
