<div dir="ltr">Thanks Eoghan for your detailed response regarding the current scenario and progress related to this project. Had been investigating about this for while since they had been documented <a href="http://docs.openstack.org/developer/ceilometer/measurements.html">here in the official ceilometer measurements page</a>. Thanks for your enlightenment!</div>

Hi Jobin,<br>
<br>
The memory utilization metering will require a new release of libvirt<br>
which will not be available for another few weeks. After that, it will<br>
depend on there being developer bandwidth available to put the ceilometer<br>
support in place for a new meter type.<br>
<br>
We have no current plans that I'm aware of to implement metering of disk<br>
utilization (in the sense of available diskspace, equivalent to that<br>
reported by say running the df command on the instance). But I could see<br>
it being a useful thing.<br>
<br>
The information is certainly available via the libvirt domain blockInfo,<br>
though there may be some wrinkles around multiple block devices versus<br>
volumes attached.<br>
<br>
In any case, please submit[1] a bug with a request for enhancement.<br>
<br>
Cheers,<br>
Eoghan<br>
