[ceilometer][octavia] polling meters

Hi again,

I did not manage to make it work, I cannot figure out how to connect all
the pieces.

pollsters.d/octavia.yaml  https://paste.xinu.at/DERxh1/
pipeline.yaml https://paste.xinu.at/u1E42/
polling.yaml https://paste.xinu.at/MZWNs/
gnocchi_resources.yaml https://paste.xinu.at/j3AX/
gnocchi_client.py in resources_update_operations  https://paste.xinu.at/no5/

gnocchi resource-type show https://paste.xinu.at/7mZIyZ/
Do you mind if you do a full example
using  "dynamic.network.services.vpn.connection" from
https://docs.openstack.org/ceilometer/latest/admin/telemetry-dynamic-pollster.html
 ?

Or maybe you can point me to the mistakes made in my configuration?
