[Telemetry][TC]Telemetry status


Hi,

we have held a presentation in Shanghai on that topic if that's of help 
for anyone:

https://www.openstack.org/summit/shanghai-2019/summit-schedule/events/23932/transitioning-your-cloud-monitoring-from-ceilometer-to-monasca

We've compared the technology of Telemetry and Monasca and how specific 
use cases like billing or auto-scaling are implemented. Monasca is a 
valid replacement option for Gnocchi.

I have to disagree with that. Monasca is used for billing in production.

Yes, we decided to use Apache Kafka as it's better suited than RabbitMQ 
to pass large loads of data with high throughput. Building the system 
around Kafka allows us to provide fault-tolerance and scalability.
