Unable to locate any Java monitoring tool

English Applications
1

I have a laptop that I did not use for Java development until now. The OS is Leap 15.2 it has installed java-11-openjdk.
I tried to start the jconsole, but I could not find it anywhere. It is not even available as a separate package. Same for Java Mission Control. Among the packages in Yast there are no Java other monitoring tools. I could download the visualvm as a standalone application, but it does not see java 11 processes.

As it is this machine is useless for developement where can I find at least the Jconsole or an alternative?

BTW. The enabled repositories are the default ones plus packman:

It’s a licensing issue – <https://en.opensuse.org/SDB:Installing_Java&gt;.

  • You’ll have to install the tools manually direct from the Oracle repositories …

Thank you. It was in the **devel **package. I didn’t install it before because I thought it referred to some specific OpenSUSE development. Instead it contains the Java development tools.

I think that that page refers to the Oracle JVM/JDK, for what I am doing the OpenJDK is enough.

But, “java-11-openjdk-devel” provides neither “Java Mission Control” (JMC) nor, “Java Flight Recorder” (JFR) – please check the OpenJDK site – <http://openjdk.java.net/projects/jmc/&gt; – <http://openjdk.java.net/jeps/328&gt;.
