Prometheus reporter for Kafka
It exposes an HTTP endpoint /metrics that returns the metrics in prometheus format
- Download the latest version from the releases
- Put the jar file in the
libs/folder of your kafka deployment - Add this line to
server.properties:metric.reporters=cloudkarafka.kafka_http_reporter - (Re)start the broker
Which metrics to return is specified by a properties file you tell the plugin where the file is by adding `` to the Kafka configuration file.
The file should look something like this:
kafka.cluster:type=Partition,topic=*,name=UnderMinIsr,partition=*
kafka.controller:type=KafkaController,name=OfflinePartitionsCount
kafka.controller:type=KafkaController,name=ActiveControllerCount
kafka.controller:type=KafkaController,name=GlobalPartitionCount
kafka.controller:type=ControllerStats,name=LeaderElectionRateAndTimeMs
kafka.controller:type=ControllerStats,name=UncleanLeaderElectionsPerSec
The plugin supports wildcards * for some parameters, so you can get metrics for all topics but without listing the names of all topics.
