  2. Open the storage node's log4j-server.properties file. 
    [root@server ~]# vim serverRoot/jon-server-3.2.GA/rhq-storage/conf/log4j-server.properties
  3. Add or edit the lines for the log threshold property (log4j.appender.R.Threshold) and the apache property (log4j.logger.org.apache.cassandra) to enable debug logging. 
    log4j.appender.R.Threshold=DEBUG
log4j.logger.org.apache.cassandra=DEBUG
