Open Stack

Hi all,

I tried to install openstack via devstack, while including ceilometer.
The install of openstack is ok. The dashborad is accessible, and everything
seem to be fine.
However, I am not able to launch ceilometer services. For instance
ceilometer-collector returns the following error, that seems related to
python coding errors. Would you please help me to fix this bug.

Thanks,
Afef
