The Administrator Log Tool allows you to tap into the log information that Java classes make available. You can indicate specific classes that you want to monitor for a certain level of log information.

Go to the following URL to use this tool:



You will have to log in with a Tomcat administrative login to get access to this tool. You can connect to individual classes and set the level of their log messages. The level varies from "SEVERE" (log only crucial errors) to "ALL" (log every message).

Be careful

Logging will cost quite a few resources because the messages are stored in memory. Too active loggers can be a severe burden on your websites performance. Be sure to disconnect loggers that you no longer need, especially if you set them to log level "ALL".

It is best practice to work like this:

  • Connect the needed loggers
  • Switch logging on (set to level other than SEVERE)
  • Do the test
  • Switch logging off (set to level SEVERE)

The Logging tool is also available in the edit environment GX WebManager, under "Maintenance > System utilities...".

For example, if you want to monitor the caching module, connect to the following classes that implement GX WebManager's caching and set their level to "FINE":

  • nl.gx.webmanager.handler.config.TSFetcherImpl
  • nl.gx.webmanager.handler.config.TSComparatorImpl
  • nl.gx.webmanager.handler.config.TimeStampTable 

Now all cache requests and decisions will appear in the log file.
