title: How to enable DEBUG level logging with Jetty from UI
body: <p>I'm trying to set the logging level to DEBUG in a Jetty instance. It is working when we add
  -Dorg.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StdErrLog
  -Dorg.eclipse.jetty.LEVEL=DEBUG  Under property file and pass it to the JVM.
  My use case is I was trying to set logging level from UI so that without restarting the server we can switch logging level.
  for example, DEBUG to WARN</p>
