About the main Studio log file

For Studio, the main log file (bdd-studio.log) contains all of the log messages.

By default the bdd-studio.log is stored in the WebLogic domain at $MW_HOME/user_projects/domains/bdd_domain/<serverName>/logs (where serverName is the name of the Managed Server in which Studio is installed).

The main root logger prints all messages to:

The console, which typically is redirected to the application server's output log.
bdd-studio.log, the log file in log4j format.
bdd-studio-odl.log, the log file in ODL format. Also stored in $MW_HOME/user_projects/domains/bdd_domain/logs

The main logger does not print messages from the com.endeca.portal.instrumentation classes. Those messages are printed to the metrics log file.
