Currently, Ceilometer only tries to connect to the external metrics/events storage services (like gnocchi) once, when it starts. If the service is not there in that moment, the Ceilometer service just sits there in error and does nothing.

In RHOSP18, Kuberntes pattern will start all the containers at the same time.

Sometimes the ceilometer agent will start before than the external service, sometimes it will not. If the first situation happens, the service does nothing.

There must be a number of reconnection attempts every 10 seconds or so to give time to external storage systems to spawn.
