Can Jprofile connect to JVM running in docker

Question

I'm new to JProfiler. I came into a problem recently. My Java app is running in docker which means the JVM is runnning in docker. But my jprofile is installed in the host machine. I know the jprofiler must connect to a JVM. So, is there anyway that the jprofiler can connect to jvm running in docker?

@PatrickAleman that would be a good answer – Spinescent

But the answer of that question is not the same thing I asked – Drusy

remote just means a subset of anything you can also do locally or with containers, therefore it is applicable here. – Pebble

Answer 1

It is similar as connects JProfiler to a remote JVM, you just need to have the JProfiler agent ready inside your container and expose the port.

This post has a step by step guide http://geekspearls.blogspot.com.au/2016/08/configure-jprofiler-92-to-profiling.html

I found I had to map the port after following the guide. docker run -p 8849:8849 imageName – Gehlbach

You can use this dockerfile; https://registry.hub.docker.com/u/gingerbeard/java8-jprofiler/dockerfile/

FROM dockerfile/java:oracle-java8
MAINTAINER gingerbeard <[email protected]>

RUN wget http://download-aws.ej-technologies.com/jprofiler/jprofiler_linux_8_1_2.tar.gz -P /tmp/ &&\
 tar -xzf /tmp/jprofiler_linux_8_1_2.tar.gz -C /usr/local &&\
 rm /tmp/jprofiler_linux_8_1_2.tar.gz

ENV JPAGENT_PATH="-agentpath:/usr/local/jprofiler8/bin/linux-x64/libjprofilerti.so=nowait"
EXPOSE 8849

CMD ["bash"]

make sure to check the ports.

Answer 3

The JProfiler GUI connects to the profiling agent that is loaded in the profiled JVM through a TCP socket.

This is always the case, also if the profiled JVM and the JProfiler GUI are running on the same machine.

Invoking "Session->Integration wizards->New remote integration" will give you the instructions to set this up manually.

I've figured it out. The right way is install jprofiler inside the container with your java app. Start the jprofiler using "docker exec" in your host machine. Then u can monitor your container in your local machine. – Drusy
