Logging issues in Storm

Hi,
For making Log4j logs to work in storm, what needs to be done?
I have used both Slf4j and Log4j directly and it works when executed as a
standalone java program (Logs get printed where they need to). However, the
moment I submit cluster (StormSubmitter) or LocalCluster, the logs dont
appear.

Even Sysouts dont get printed. I see some of the sysouts in Supervisor.log
but the sysouts from spouts and bolts are not there anywhere.

I came across cluster.xml under .../storm/logback which seems to indicate
all loggers should be configured here?

Any ideas on what I might be missing?

Regards,
Kashyap

Thanks for the direction. I don't see my logs there. I am still to try out
modifying the cluster XML for adding additional appenders.

Do the logs come in the worker logs even if it is a local cluster mode too?

Thanks!
Kashyap

Try looking under $STORM_HOME/logs/worker-SLOT.log for the worker that is running your code. SL4j and log4j get bridged back to Storm's native logback logger.
