Need Clarification on Protobuf, Kafka and Prometheus interaction about firehose HOT 2 CLOSED

Hi @liamhoganIBM,

Prometheus sink on firehose is not purposed for connecting from Kafka to Prometheus instances directly, since Prometheus is pull-based. So Prometheus sink on firehose is purposed to push the events from Kafka to TimeSeries database, eg:cortex. The events from Kafka will be parsed to prometheus exposition format

example:

metric_name{label_name1=label_value1, label_name2=value2} metric_value

From the example config on guideline section,
if SINK_PROM_METRIC_NAME_PROTO_INDEX_MAPPING set to {"2":"tip_amount","1":"feedback_ratings"}, there will be two metric names stored in tsdb.

tip_amount <tip_amount_value>
feedback_ratings <feedback_ratings_value>

from firehose.

Closing because of inactivity.
