Ian Downes resolved MESOS-687.
------------------------------
Resolution: Fixed
> slave should export perf hardware counters when available
> ---------------------------------------------------------
>
> Key: MESOS-687
> URL: https://issues.apache.org/jira/browse/MESOS-687
> Project: Mesos
> Issue Type: Story
> Components: slave
> Reporter: brian wickman
> Priority: Minor
>
> It would be very valuable for the slave resource monitor to export hardware
> counters. There are a few ways this could be done -- either by invoking perf
> directly or by accessing the counters via the syscall/read interface
> described by http://lxr.free-electrons.com/source/tools/perf/design.txt I'd
> imagine this would just get plumbed through Isolator::usage in the end and
> get exported via the resource monitor endpoint.
> Correct me if I'm wrong but there's currently no information exposed
> (programmatically) at the granularity level of executor, so I don't really
> know how this information could ever make its way into the hands of a
> scheduler for the purpose of making better scheduling decisions vis-a-vis
> things like task-level interference. Given Google's CPI paper
> (http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/en/us/pubs/archive/40737.pdf)
> it sounds like something worth investigating.
