----------------------------------
Summary: Allow configuration of MetricsReporter subclasses
Key: KAFKA-3711
URL: https://issues.apache.org/jira/browse/KAFKA-3711
Project: Kafka
Issue Type: Improvement
Components: clients, streams
Reporter: Jeff Klukas
Assignee: Guozhang Wang
Priority: Minor
Fix For: 0.10.1.0
The current interface for attaching metrics reporters to clients allows only
defining a list of class names, but provides no means for configuring those
reporters.
There is at least one existing project
(https://github.com/apakulov/kafka-graphite) that solves this problem by
passing additional properties into the client, which then get passed on to the
reporter. This seems to work quite well, but it generates warnings like {{The
configuration kafka.graphite.metrics.prefix = foo was supplied but isn't a
known config.}}
Should passing arbitrary additional parameters like this be officially
supported as the way to configure metrics reporters? Should these warnings
about unrecognized parameters be removed?
Perhaps there should be some mechanism for registering additional configuration
parameters for clients to expect?
