<p>Hi Emilien,</p>
<p><br>
</p>
<p>We had this project of our own for a couple years and it was not meant to replace Ceilometer at all. For our billing use case, yes it did replace Ceilometer because scaling issues. We just wanted to propose it to the community as a matter of sharing knowledge. </p>
<p><br>
</p>
<p>This system just collects events that we/you care about and store them as a stream so you could reuse them later (in our case billing). And by the way Almanach doesn't do billing at all. You could even plug it to Cloud Kitty as a data source if you want. </p>
<p>So currently I'm not sure there is a project that does the same thing in Telemetry unless I'm mistaken. Yes there was Ceilometer, but for reason of api performance issue when hitting a huge DB with a lot of historic data. It was not scalling at all. Right
now, not sure where Ceilometer is going in terms of dev and there is Aodh, but from what I read, it's for alerting purposes.</p>
<p><br>
</p>
<p>So now you know the "Why we are here now"...</p>
<p><br>

<br>
I am failing to understand why we create projects to replace official<br>
projects that would have the same mission statement or common<br>
technical goals. We saw it with Monasca and AFIK it didn't work very<br>
well.<br>
Have you engaged collaboration with Telemetry team to work together as<br>
a community and propose your use-case to the roadmap if some feature<br>
was missing?<br>
<br>
I'm very interested to know from "Almanach" developers why we're here<br>
now. I personally like to think OpenStack contributors work as a<br>
community and meet common goals by communicating on the appropriate<br>
channels.<br>
Please correct me if I'm wrong in the case this project is totally<br>
doing something else, my knowledge in Telemetry is limited from my<br>
user perspective.<br>
