I don't get it, I have thought your goal was to create alarm triggered on
event. And for this you need Aodh and Ceilometer (not Panko).
You have to do https://docs.openstack.org/developer/aodh/event-alarm.html#configuration
manually to get events emitted by Ceilometer received by Aodh.

No, Panko is for storage of event in a database (It's a API and a
Ceilometer dispatcher plugin). Events are still built from notification
by Ceilometer (agent-notification).
Rephrase from Ceilometer point of view. Ceilometer send events to Aodh AND Panko.
