Error opening zip file or JAR manifest missing : /etc/jmx_exporter/jmx_prometheus_javaagent.jar

I'm trying to add JMX exporter on my kafka-zookeeper. For this I've followed these steps:

copied jmx_prometheus_javaagent.jar to the current directory
mounted volume with /jmx_prometheus_javaagent.jar:/etc/jmx_exporter
and added the argument like this: KAFKA_OPTS: -javaagent:/etc/jmx_exporter/jmx_prometheus_javaagent.jar=7071:/etc/jmx_exporter/kafka_config.yml

I'm downloading jmx_prometheus_javaagent-0.20.0.jar from here https://github.com/prometheus/jmx_exporter/releases/tag/0.20.0. And remaning it to jmx_prometheus_javaagent.jar.

Here is the complete docker-compose.yml file:

Right now, I'm stuck and don't know what to do with it? I surely can't use other solutions, as everything is self hosted, on top of that having multiple dashboard to monitor stuffs will be really absurd.

Solution

Ended up using helm chart for kafka, with the following details:

image:

image:
  registry: docker.io
  repository: bitnami/kafka
  tag: 3.5.0-debian-11-r4
  digest: ""

And it has builtin JMX support to it. All I had to do is, enable it:

  jmx:
    ## @param metrics.jmx.enabled Whether or not to expose JMX metrics to Prometheus
    ##
    enabled: true
