Hello,

I try to configure ceilometer for usage in billing. I use mitaka/newton 
mix to install ceilometer with gnocchi support. For metrics gnocchi 
works great, but for billing looks like need more event based metrics. 
As I understand, for events we should use Panko. But for Panko there is 
lack of documentation, someone have some kind howto to configure panko 
in ceilometer? Maybe someone have some suggestions what I should to look 
at to build telemetry for billing purposes?

Thanks and best regards,

Martins
