regarding ceilometer+oslo.messaging backend[1]. i feel like i should
mention, i'm not sure how you guys are using the query but i should
mention that is not the correct way to use Ceilometer meters as it
currently isn't measuring anything (see hardcoded - volume:1)<br>
<br>
again, i'm not sure what query you are utilising, but i would
suggest you probably change this to use Events (possibly with
elasticsearch) rather than Meters because it currently doesn't seem
to make much sense.<br>

<div dir="ltr">Hi stackers,
<div><br>
</div>
<div>Intro</div>
<div>-------</div>
<div><br>
</div>
<div>It's not a big secret that OpenStack is huge and
complicated ecosystem of different</div>
<div>services that are working together to implement OpenStack
API. </div>
<div><br>
</div>
<div>For example booting VM is going through many projects and
services: nova-api, nova-scheduler, nova-compute, glance-api,
glance-registry, keystone, cinder-api, neutron-api... and many
others. </div>
<div><br>
</div>
<div>The question is how to understand what part of the request
takes the most of the time and should be improved. It's
especially interested to get such data under the load. </div>
<div><br>
</div>
<div>To make it simple, I wrote OSProfiler which is tiny library
that should be added to all OpenStack </div>
<div>projects to create cross project/service tracer/profiler. </div>
<div><br>
</div>
<div>Demo (trace of CLI command: nova boot) can be found here: <a href="http://boris-42.github.io/ngk.html" target="_blank"></a><a href="http://boris-42.github.io/ngk.html" target="_blank">http://boris-42.github.io/ngk.html</a></div>
<div><br>
</div>
<div>This library is very simple. For those who wants to know
how it works and how it's integrated with OpenStack take a
look here: <a href="https://github.com/openstack/osprofiler/blob/master/README.rst" target="_blank">https://github.com/openstack/osprofiler/blob/master/README.rst</a></div>
<div><br>
</div>
<div>What is the current status? </div>
<div>-----------------------------------</div>
<div><br>
</div>
<div>Good news: </div>
<div>- OSprofiler is mostly done </div>
<div>- OSprofiler is integrated with Cinder, Glance, Trove &
Ceilometer </div>
<div><br>
</div>
<div>Bad news: </div>
<div>- OSprofiler is not integrated in a lot of important
projects: Keystone, Nova, Neutron </div>
<div>- OSprofiler can use only Ceilometer + oslo.messaging as a
backend </div>
<div>- OSprofiler stores part of arguments in api-paste.ini part
in project.conf which is terrible thing</div>
<div>- There is no DSVM job that check that changes in
OSprofiler don't break the projects that are using it </div>
<div>- It's hard to enable OSprofiler in DevStack</div>
<div><br>
</div>
<div>Good news: </div>
<div>I spend some time and made 4 specs that should address most
of issues: </div>

</div>
<div><br>
</div>
<div>Let's make it happen in Mitaka!</div>
<div><br>
</div>
<div>Thoughts?</div>
<div>By the way somebody would like to join this effort?) </div>
