The logging level of these files is controlled by the LOGLEVEL macro in eucalyptus.conf. This macro controls the level of logging output that appears in various eucalyptus log files. The options are DEBUG, INFO, WARN, ERROR, and FATAL (in descending order of verbosity). The default is DEBUG (everything).
