--------------------------------
Summary: Rewrite perf events code
Key: MESOS-3399
URL: https://issues.apache.org/jira/browse/MESOS-3399
Project: Mesos
Issue Type: Improvement
Reporter: Cong Wang
Assignee: Cong Wang
Priority: Minor
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.
