Note:
- You can use any, or multiple of the input mechanisms
- multi-tenant setups need tsdb-gw in between Grafana and Graphite to authenticate requests before proxying requests to Graphite/Metrictank
- tsdb-gw can also be used as a public ingestion point with native metrics2.0 input, for multi-tenant setups. Clients can then use carbon-relay-ng to send data.
