WRT to times - mock_runner.sh does print those out to the output page
(surrounded by many asterisks and other symbols...)

WRT separation of logs - we already mostly have that, you can see
individual step logs in the job artifacts. For example for one of the
jobs above:

http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc24-x86_64/5991/artifact/exported-artifacts/logs/mocker-fedora-24-x86_64.fc24.check-patch.sh/check-patch.sh.log

But yeah, we could probably make the output in the main Jenkins output
page better. That would require potentially breaking changes to
"mock_runner.sh", so I'd rather focus on ultimately replacing it...

We do already have https://ovirt-jira.atlassian.net/browse/OVIRT-682
for discussing this issue.

Jenkins (partially) gives us that, see here:
http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc24-x86_64/buildTimeTrend

I completely agree that the UX here is not as good as it can and
should be, and we do have plans to make it A LOT better, please bare
with us in the meantime...
