I am using JMX exporter for kafka related metrics. We are running it as javagent as shown below:-

export KAFKA_OPTS='-javaagent:/jmx/jmx_prometheus_javaagent-0.12.0.jar=7097:/kafka/kafka-jmx-metrics.yaml'

It shows high cpu usage(90%-100%) for a period of 20 minutes approx. once every day. Is it a known issue?

Thanks,

Brajesh

Hi Team,

I am facing the same issue with Kafka.

We are running it as below,

COPY jmx_prometheus_javaagent-0.12.0.jar /opt/$KAFKA_DIST/jmx_prometheus_javaagent-0.12.0.jar
COPY config.yml /opt/$KAFKA_DIST/config.yml
RUN set -x \
&& ln -s /opt/$KAFKA_DIST $KAFKA_HOME \
