Hi everyone, I'm currently finishing our cloudkitty implementation, but I'm facing an issue. For now, our cloudkitty-processor process raise a traceback like this: http://paste.openstack.org/show/Y2ZiYPtZSKzvZk93yNWC/ I can't find any reliable documentation describing how to use prometheus with cloudkitty, so I'm kind of using the guess/read the code way to integrate it, but I'm a bit confused so far. My current metric.yml look like this: http://paste.openstack.org/show/6X23ZfVm1iDMruGy3Gpp/ I've created the appropriate group/service/threshold etc but it still continues to raise the same error. I'm using this openstack_exporter: https://github.com/openstack-exporter/openstack-exporter/releases/tag/v1.1.0 I'm running a Train release Openstack platform if it can help. So, if anyone is having a successful cloudkitty/prometheus integration willing to give a hand, I'll be more than happy ;-) Thanks!
