<div dir="ltr"><div>Hi all,</div><div><br></div><div>thanks a lot for your answers.</div><div>We know that ceilometer is not able to receive notifications from openstack components (like nova), when installed with XCP. But both our goal and testing approach are different. The strange behaviour we are talking about concerns ceilometer-collector and it's usage of kombu for AMQP. We added debugging output in ceilometer.openstack.common.rpc.impl_kombu.ConsumerBase.consume._callback to see whether or not some of the 58 topic consumers would receive anything on their exchange and topic. For that purpose we wrote a small test programm to publish a simple message on a configured exchange and topic to see a reaction from ceilometer-collector, but we received nothing. The rabbitmq server itself is working fine, as we can consume our sent message with another small test programm. We think this might be a configuration issue, but we've been through our setup several times and can't find the issue.</div>

<pre style="font-size:10pt;font-family:Tahoma;word-wrap:break-word">Hi,
Ceilometer is currently KVM specific.
I hope this will get fixed during the icehouse cycle, however ceilometer and XenServer/XCP do not work together quite yet.

</div>
<div>I followed this document: <a href="http://docs.openstack.org/havana/install-guide/install/apt/content/ch_ceilometer.html" target="_blank">http://docs.openstack.org/havana/install-guide/install/apt/content/ch_ceilometer.html</a></div>

</div>
<div>My Ceilometer does not receives any data... Still "0 bytes" showing at the Admin Panel (/admin/metering)...</div>
<div><br>
</div>
<div>I installed Ceilometer endpoint / mongodb / packages in a dedicated Virtual Machine, not at the crowd controller, keystone users / info created okay but, it doesn't seems to be working as expected.</div>
<div><br>
</div>
<div>Also, I noted that nothing is changed at the "nova.conf" of the controller itself, only nova.conf from compute node gets updated for Ceilometer AND, the Network Node also haven't changed.</div>
<div><br>
</div>
<div>Let us know if it is working for you...</div>

<div>Hi all,</div>
<div><br>
</div>
<div>We have launched devstack to install openstack, while including ceilometer. </div>
<div>We use XCP as hypervisor, Ubuntu 12.04. The used openstack version is 2014.1.</div>
<div><br>
</div>
<div>When running ceilometer-collector, consumers get registered on every topic and exchange, but never actually consume anything. We tested this with different amqp libraries, while sending messages to those topics and exchanges. Not even ceilometer.openstack.common.rpc.impl_kombu.BasicConsumer._callback
gets called.</div>
<div><br>
</div>
<div>As we are interested in notifications from our own source, has anyone experienced this behaviour or a working system with notifications?</div>
<div><br>
</div>
<div>Thank you</div>
