---------------------------------
Summary: Perf isolator event validation issues
Key: MESOS-3292
URL: https://issues.apache.org/jira/browse/MESOS-3292
Project: Mesos
Issue Type: Bug
Reporter: Paul Brett
Linux perf isolator currently validates events by running the installed perf
command once at slave startup to verify that no error is raised when the event
is requested. No checking is done at startup to validate that the perf event
is supported by Mesos in the PerfStatistics message.
However, perf is an external program and can be upgraded while the slave is
running, possibly resulting in a change of perf Version and supported events or
output formats.
We should validate events against PerfStatistics at startup and deal with on
the fly perf upgrades.
