Hi all,
I have a Mitaka environment where glance, nova and cinder use ceph
(rbd) as storage backend, that works perfectly fine. Now I'm trying to
get meters from my rbd pool with ceilometer, but libvirt fails to read
information, the ceilometer-polling.log says

This bug [1] describes the issue, but it seems to be a libvirt issue,
not ceilometer.
According to [2] it should be possible to retrieve those meters.
I followed ceph docs to install the rados-gateway, I integrated
keystone authentication, at least I don't get any errors regarding
authentication and swift command seems to work.
Then I added the meters described in [2] to the /etc/ceilometer/pipeline.yaml
---cut here---
control1:~ # cat /etc/ceilometer/pipeline.yaml
---
sources:
[...]
- name: radosgw_source
interval: 600
meters:
- "radosgw.objects"
- "radosgw.objects.size"
- "radosgw.objects.containers"
- "radosgw.api.request"
- "radosgw.containers.objects"
- "radosgw.containers.objects.size"
sinks:
- meter_sink
[...]

I believe I have completed all required steps, but I still get the
libvirt errors in ceilometer (both kvm and xen hypervisor).
Now I'm starting to wonder if rados-gw really is the right choice
here. Has anybody figured out a way to retrieve rbd meters with
ceilometer?
Regards,
Eugen
