Do you mean the JMX beans don't provide metrics? In that case you should open an issue on https://github.com/apache/zookeeper. The `jmx_exporter` exposes metrics from JMX beans to Prometheus. If the...

Hi Kunal, I looked up a few of these, but I can't really see how they are related to the `jmx_exporter`. Are these vulnerabilities in the JAR file, or is...

Looks like Bitnami pushed a [new image with the 0.15.0 tag today](https://hub.docker.com/layers/bitnami/jmx-exporter/0.15.0/images/sha256-b7dd3941bf9d1661836c9a152dd3579f7ba191033cd9da377a1f4de72e1fa6cf?context=explore). Could you check if the CVEs are still there? If so, I think this should more be an...

The last argument should be the JAR file of your application that you want to monitor, like ``` java -javaagent:./jmx_prometheus_javaagent-0.16.1.jar=8080:config.yaml -jar yourJar.jar ```

Could you try to run the same command without the `-javaagent:./jmx_prometheus_javaagent-0.16.1.jar=8080:config.yaml` parameter? I assume that the `Main-Class` attribute is missing in your application JAR, and that's causing the error.

Wildfly (and JBoss) use `java.util.logging` for logging, and the implementation assumes that `org.jboss.logmanager.LogManager` is used as the underlying log manager. The issue is, if anything touches `java.util.logging` before Wildfly, the...

The poll interval is configured in the Prometheus server. The javaagent just responds to requests coming from the Prometheus server, so it exposes metrics every time it gets a request...

The configuration in Grafana says how often it pulls data from the Prometheus server, the configuration in Prometheus says how often it scrapes data from the exporter. A scrape interval...

This means that another process is also trying to use port `8686` on the same host.

I didn't find the time to look into this yet. Is there any chance you can reproduce this by extending the `CassandraMetrics` in `JmxCollectorTest`?
