<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">All projects (except maybe Swift) should be moving to use oslo.logging. Therefore, your longterm fix is the right way to go. When you find log issues like
the one in ./neutron-metadata-agent.log, file it as a bug so that the code can be refactored as either a bug fix or a “while you’re in there” step.<o:p></o:p></span></p>

<div>
<p class="MsoNormal">We have a high priority bug in 6.0: <a href="https://bugs.launchpad.net/fuel/+bug/1401852">
https://bugs.launchpad.net/fuel/+bug/1401852</a>. Here is the story.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<p class="MsoNormal">Our openstack services use to send logs in strange format with extra copy of timestamp and loglevel:<o:p></o:p></p>
<div>
<div>
<p class="MsoNormal">==> ./neutron-metadata-agent.log <==<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">2014-12-12T11:00:30.098105+00:00 info: 2014-12-12 11:00:30.003 14349 INFO neutron.common.config [-] Logging enabled!<o:p></o:p></p>
</div>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">And we have a workaround for this. We hide extra timestamp and use second loglevel.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In Juno some of services have updated oslo.logging and now send logs in simple format:<o:p></o:p></p>
</div>
<div>
<div>
<p class="MsoNormal">==> ./nova-api.log <==<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">2014-12-12T10:57:15.437488+00:00 debug: Loading app ec2 from /etc/nova/api-paste.ini<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
</div>
<div>
<p class="MsoNormal">In order to keep backward compatibility and deal with both formats we have a dirty workaround for our workaround: <a href="https://review.openstack.org/#/c/141450/">https://review.openstack.org/#/c/141450/</a><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Long term fix here is to update oslo.logging in all packages. We can do it in 6.1.<o:p></o:p></p>
