Accessing local actuator JMX endpoints using VisualVM

Question

``I am trying to access the JMX actuator endpoints using jvisualvm.

I have done the following

• used the actuator service sample project (gs-actuator-service-complete)
• added property spring.jmx.enabled=true
• set the following Java options in the build.gradle file

bootRun { jvmArgs = ["-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false"] }

• started the app using ./gradlew bootrun
• launched jvisualvm
• tried service:jmx:rmi:///jndi/rmi/://localhost:9001/jmxrmi and service:jmx:remote+http://localhost:9001 in the Add JMX Connection dialog.
• the following pictures show the Add JMX Connection dialog and error

Error

In particular

• is there anything else that needs to be configured?
• what is the correct value to put into the Add JMX Connection dialog to allow me to see the actuator/metrics and other endpoints?

First you need to install 'VisualVM-MBeans' plugin, since the data are exported as MBeans. Once you have 'VisualVM-MBeans' plugin installed, just open actuator service sample project from VisualVM and switch to 'MBeans' tab. Spring MBeans can be accessed under org.springframework.boot on left tree.
