</div>Yes, there seems to be an attitude among several people in the community that the Ceilometer team denies that there are issues and refuses to work on them. Neither of those things is the case from our perspective.<br>

It has been a while since I last looked at it, so the situation may have changed, but some of the reasons stacktach would not be a full replacement for ceilometer include: it only works with AMQP; it collects notification events, but doesn’t offer any metering ability per se (no tracking of values like CPU or bandwidth utilization); it only collects notifications from some projects, and doesn’t have a way to collect data from swift, which doesn’t emit notifications; and it does not integrate with Heat to trigger autoscaling alarms.</div><div><br></div><div>We did work with a few of the Stacktach developers on bringing event collection into ceilometer, and that work is allowing us to modify the way we store the meter data that causes a lot of the performance issues we’ve seen. That work is going on now and will be continued into Kilo, when we expect to be adding drivers for time-series databases more appropriate for that type of data.</div><div><br></div><div>We’ve just finished the TC meeting where some of these issues were discussed, but I want to reiterate my stance here more publicly. As a community, we need to be able to talk about the technical shortcomings of projects. We need to be able to say, for example, “ceilometer, your runtime performance isn’t good enough, you need to work on that rather than adding features.” But we must also be willing give the team in question the benefit of the doubt that they will work on the problem before we bring out the pitchforks of de-integration, because there are serious community implications around that level of rejection.</div><div><br></div><div>Doug</div><br><blockquote type="cite"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote">

</div>What “cross-project efforts” are we talking about? The liaison program in Oslo has been a qualified success so far. Would it make sense to extend that to other programs and say that each project needs at least one designated QA, Infra, Doc, etc. contact?<br>
