How to enable logging in FUSE ESB 4.x

Resolution

The default logging level can be configured by editing <Fuse ESB 4.x>/etc/org.ops4j.pax.logging.cfg.

Log data is written to <Fuse ESB>/data/logs/servicemix.log.
The logging sub shell in the servicemix console can also be used to display logging information:

karaf@root>log:display -n 25

This displays the last 25 lines from the log.

karaf@root>log:tail

This is equivalent to unix tail command and will keep appending new entries to the display whenever log is updated.

karaf@root>log:display-exception

This displays the last exception thrown

karaf@root>log:get

This displays the current log level.

karaf@root>log:set DEBUG

This dynamically sets the log level to DEBUG for all packages.

karaf@root>log:set DEBUG org.springframework

This dynamically sets the log level for the org.springframework package to DEBUG.
