Then, use “Run/Debug Configuration” Dialog to create a remote run/debug configuration. Make sure your publish port 5005 to your Docker host when starting your Docker container.Īs an example, if you use IntelliJ as your Java IDE to debug, you can start by opening the project that contains the source code of your Java application. agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 To debug your Java application remotely using your favorite IDE, use the following JVM option to start your application assuming the debugging agent is running at port 5005: Log in to your New Relic account and your should see your application shows up in the application list. Start your Java application inside the container with the following JVM option:Ħ.
Include the unzipped folder in your Docker imageĥ. Make sure to publish container’s port 9090 as the Docker host port 9090 when starting the Docker container: Where .name specifies the host name or IP address that your JMX client uses to connect to the target Java application. To enable remote JMX connection, you need to run your Java application in the Docker container with JVM options like these: The tool connects to local Java processes directly, but in order to connect to a Java application running inside a Docker container, it needs to connect through a JMX port.
JPROFILER VS JAVA MISSION CONTROL INSTALL
You can also install it as a separate application. It comes with JDK and can be start by running “ jvisualvm” command. VisualVM is a GUI tool that monitors and profiles a JVM. Connect VisualVM to an Application through JMX agents In this blog post, I will describe a couple of ways to monitor such Java applications. But when the Java application runs inside a Docker container on a Docker host, it becomes challenging to monitor them using tools running locally, even when the Docker host is just a virtual machine running on your desktop.
It’s usually straightforward to do that if an applications is running as a Java processes on your local machine. Java developers need to monitor and trouble-shoot Java applications from time to time.
