Quarkus JMX monitoring

[marichka-spin]

Hello, team I'm new to Quarkus and I'm trying to migrate our small connector application from Spring to Quarkus. But The main issue that I'm stuck with - is it possible to access application MBeans via remote jmx connection. My application has code that registers custom MBean and also I added micrometer dependency to observe monitoring MBeans. I started application via IntelliJ runner with following vm options -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9090 -Dcom.sun.management.jmxremote.rmi.port=9090 -Dcom.sun.management.jmxremote.host=0.0.0.0 -Djava.rmi.server.hostname=0.0.0.0 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.local.only=false If I connect jconsole as to local process I can observe my custom MBean domain and 'meter' domain But if I connect as to remote process neither of domains I don't observe. Could you point me out what I'm doing wrong Also when I tried to run application in production mode (java -jar ....) vm options didn't apply at all.

@marichka-spin are you also setting those jmx properties when you run with java -jar... ?

@brunobat I'm doing: java -jar ./target/quarkus-app/quarkus-run.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9090 -Dcom.sun.management.jmxremote.rmi.port=9090 -Dcom.sun.management.jmxremote.host=0.0.0.0 -Djava.rmi.server.hostname=0.0.0.0 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.local.only=false

Options seems to not applied at all, jconsole is not connecting to remote process with param 'localhost:9090'

The command looks ok, it works for me on Linux and Temurin 21:

Can you please add a reproducer project to this issue?

Hello, @brunobat My set up is MacOS and Azul jdk 17 So I created test project https://github.com/marichka-spin/jmx-with-quarkus What I did java -jar ./target/quarkus-app/quarkus-run.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9090 -Dcom.sun.management.jmxremote.rmi.port=9090 -Dcom.sun.management.jmxremote.host=0.0.0.0 -Djava.rmi.server.hostname=0.0.0.0 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.local.only=false then I run jconsole localhost:9090 I've got - Connection refused

If I connect as local process - everything is ok. But I case with java code:

JMXServiceURL url = new JMXServiceURL(String.format(CONNECTION_STRING_TEMPLATE,"localhost:9090")); JMXConnector jmxc = JMXConnectorFactory.connect(url, new HashMap<>()); MBeanServerConnection mbsc = jmxc.getMBeanServerConnection(); log.info("MBeanServer default domain = " + mbsc.getDefaultDomain()); return mbsc; I also can't connect

Hi @brunobat, In one of the previous issues, I found that Quarkus doesn't support JMX but that was an old comment. I was trying to connect jmx for my application (Keycloak 21.1.2.4.6 + Quarkus 2.13.8.Final) but facing a problem. More details over here: Error Details

Wanted to check if its supported now and specifically from which version onwards? Thanks!

That issue is about JMX on native mode. It's not the case here.

@marichka-spin, sorry, but your command worked for me on Fedora 42 Linux, using Temurin 21. Please try other JDK, operating system or double-check your firewall.
