<div dir="ltr">Thanks a lot Eoghan for your detailed response. I have enabled instance usage auditing in <a href="http://pastebin.ubuntu.com/5887592/">my nova.conf</a>. Is there anyway I could get these meters(memory and disk utilization) for VM's provisioned using OpenStack?<div>

Hey Jobin,<br>
<br>
Thanks for your perceptive question.<br>
<br>
The reason is that the conduits for gathering CPU metering and memory<br>
metering are quite different in ceilometer currently:<br>
<br>
* cpu/cpu_util are derived by polling the libvirt daemon<br>
<br>
* memory is derived from the "compute.instance.exists" notification<br>
sent by nova<br>
<br>
(This is the pollster versus notification-handler dichotomy you'll<br>
see throughout ceilometer).<br>
<br>
The reason you're not seeing the memory meter being collected is<br>
probably because you don't have instance usage auditing enabled in<br>
your nova config (see the "Configure nova" section in [1]).<br>
<br>
However, be warned that this meter is probably not the memory<br>
utilization statistic that you're expecting. Rather it's likely to<br>
be a static value reflecting the quantum of memory allocated by the<br>
hypervisor to the instance (as opposed to the sort of number you'd<br>
see when running "free -m" on the instance).<br>
<br>
I'm looking into adding support for more useful memory utilization<br>
metering (that could for example drive autoscaling logic), but this<br>
will require usage of an upcoming release of libvirt.<br>
<br>
Cheers,<br>
Eoghan<br>
