thanks for your interest in Watcher

Watcher can stream data captured by Ceilometer. Regarding the Ceilometer
db, we had performance issues when querying the database so we decided to
use streamed data instead.

actually watcher can do both as we capture the data stream

today we are supporting InfluxDB and we plan to add OpenTSDB in the coming

no we do not use this functionality today but we should definitely discuss

I will do it, thank you
