Jie Yu updated MESOS-2590:
--------------------------
Sprint: Twitter Mesos Q1 Sprint 6 (was: Mesosphere Q1 Sprint 6 - 4/3)
> Let the slave control the duration of the perf sampler instead of relying on
> a sleep command.
> ---------------------------------------------------------------------------------------------

> Key: MESOS-2590
> URL: https://issues.apache.org/jira/browse/MESOS-2590
> Project: Mesos
> Issue Type: Improvement
> Reporter: Jie Yu

> Right now, we use a sleep command to control the duration of perf sampling:
> {noformat}
> sudo perf stat -a -x, --log-fd 1 --pid 10940 -- sleep 10
> {noformat}
> This causes an additional process (i.e., the sleep process) to be forked and
> causes troubles for us to terminate the perf sampler once the slave exits
> (See MESOS-2462).
> Seems that the additional sleep process is not necessary. The slave can just
> monitor the duration and send a SIGINT to the perf process when duration
> elapsed. This will cause the perf process to output the stats and terminate.
