Review request for mesos, Benjamin Bannier and Till Toenshoff.
Changes
-------
Addressed issues.
Bugs: MESOS-3082
https://issues.apache.org/jira/browse/MESOS-3082
Repository: mesos
Description
-------
Virtual machines may not always support 'CPU performance counters'. Tests
trying to collect to 'cycle' value of 'perf' will fail under these
circumstances. This will be avoided by disabling these tests if 'perf' hardware
events are not available.

Testing
-------
Running `sudo ./bin/mesos-tests.sh
--gtest_filter="*ROOT_CGROUPS_Perf:*ROOT_CGROUPS_Sample:*ROOT_CGROUPS_UserCgroup:*CGROUPS_ROOT_PerfRollForward:*ROOT_Sample"`
1) In a Linux VM without 'CPU performance counters': This doesn't run the tests
and shows an error message that 'cycles' is not available, as expected
2) In a Linux VM without 'perf': This doesn't run the tests and shows an error
message that 'perf' is not installed, as expected
3) On OSX: This doesn't run the tests and shows an error message that 'perf' is
not available, as expected
4) On native Linux (i.e. with 'CPU performance counters'): This runs the tests.
Thanks,
Jan Schlicht
