Description

Our current code base invokes and parses `perf stat`, which sucks, because cmdline output is not a stable ABI at all, it can break our code at any time, for example MESOS-2834.

We should use the stable API perf_event_open(2). With this patch https://reviews.apache.org/r/37540/, we already have the infrastructure for the implementation, so it should not be hard to rewrite all the perf events code.
