We have a high priority bug in 6.0:
https://bugs.launchpad.net/fuel/+bug/1401852. Here is the story.

Our openstack services use to send logs in strange format with extra copy
of timestamp and loglevel:
==> ./neutron-metadata-agent.log <==
2014-12-12T11:00:30.098105+00:00 info: 2014-12-12 11:00:30.003 14349 INFO
neutron.common.config [-] Logging enabled!

And we have a workaround for this. We hide extra timestamp and use second

In Juno some of services have updated oslo.logging and now send logs in
simple format:
==> ./nova-api.log <==
2014-12-12T10:57:15.437488+00:00 debug: Loading app ec2 from

In order to keep backward compatibility and deal with both formats we have
a dirty workaround for our workaround:

As I see, our best choice here is to throw away all workarounds and show
logs on UI as is. If service sends duplicated data - we should show
duplicated data.

Long term fix here is to update oslo.logging in all packages. We can do it
in 6.1.
