Graphite write proxy
The Graphite write proxy accepts the ingest requests sent by Carbon-relay-ng and then translates the incoming Graphite
metrics into Prometheus metrics.
Once the metrics have been translated into Prometheus they get forwarded to the GEM distributor, which handles them the
same way as it would handle any other Prometheus remote_write
requests.
The Graphite to Prometheus metric translation differentiates between untagged Graphite metrics and tagged Graphite
metrics, the name mapping scheme for the two looks as following:
Untagged Graphite metrics
Graphite metric: some.test.metric
In Prometheus: graphite_untagged{__n000__="some", __n001__="test", __n002__="metric"}
Tagged Graphite metrics
Graphite metric: some.test.metric;my_tag=my_value;another_tag=another_value
In Prometheus: graphite_tagged{name="some.test.metric", my_tag="my_value", another_tag="another_value"}
