Error in Kafka startup with the JMX exporter - java.lang.IllegalArgumentException: Collector already registered that provides name: jmx_scrape_duration_seconds

[karan alang <ka...@gmail.com>]

Hi All,
I'm getting error in starting up Kafka, with the JMX exporter passed as
java agent.
Error is as shown below, any ideas ?

I'm trying to integrate Prometheus to collect Kafka metrics.


[root@nwk2-bdp-kafka-06 kafka]# KAFKA_OPTS="$KAFKA_OPTS
-javaagent:/usr/hdp/2.5.3.0-37/prometheus/jmx_prometheus_javaagent-0.9.jar=7071:/usr/hdp/2.5.3.0-37/prometheus/jmx_exporter.yaml"
