OX Logging
This information is valid until 7.4.1 (included)

Synopsis: This describes the logging of OX until backend version 6.22.6, which was delivered with AppSuite 7.4.2. The new system is described in AppSuite:OX Logging.

Open-Xchange loglevels

The loglevel Open-Xchange backend is using for each single class can be defined in the file /opt/open-xchange/etc/file-logging.properties.

To increase the loglevel of the complete Open-Xchange software stack, set

.level = ALL

on top of that file.

As also explained on top of the same file, the following loglevels exist:

  • ALL
  • INFO
  • FINE

When you changed any value, a restart of the Open-Xchange server is required.

Change loglevel without restarting Open-Xchange

It is also possible to change the loglevel while Open-Xchange is running via JMX. This can be achieved by whatever JMX tool you want or by the tool showruntimestats.

Given the same example as above, changing loglevel to ALL of the complete Open-Xchange stack, run

$ /opt/open-xchange/sbin/showruntimestats -d 'java.util.logging:type=Logging!setLoggerLevel!!ALL!'

and to revert back either restart Open-Xchange or run

$ /opt/open-xchange/sbin/showruntimestats -d 'java.util.logging:type=Logging!setLoggerLevel!!INFO!'

Note: Changing loglevel via this tool does not change it permanently. After a restart, the values from the file /opt/open-xchange/etc/file-logging.properties are used again.

If you want to change the loglevel of just a part of the software, e.g. the SOAP api, run

$ /opt/open-xchange/sbin/showruntimestats -d 'java.util.logging:type=Logging!setLoggerLevel!com.openexchange.soap.cxf.logger!ALL!'

When you install the complete java sdk, you can use the jmx console:

$ jconsole service:jmx:rmi:///jndi/rmi://localhost:9999/server

Note: That requires a X11 connection.
