I am trying to debug how the ssh-slaves is behaving but the Jenkins documentation from https://wiki.jenkins-ci.org/display/JENKINS/Logging is extremely incomplete.

I added a new logger and added:

  • "hudson." with ALL
  • "org.jenkinsci.plugins." with ALL

Still the new log added is not updated at all.

Also, I found no information on how to enable logging for everything, empty, start or what?

Update: I tried to add -Djava.util.logging.loglevel=FINE to the command line starting Jenkins but to my surprise it did not had any effect on the JENKINS_LOG but it did had an effect on the log you can check on the GUI.

java jenkins java.util.logging
