When you start Essbase Administration Server, a log file is created in WL_DOMAIN_HOME/servers/WEBLOGIC_NAME/logs/easserver.log. WL_DOMAIN_HOME is the directory to which WebLogic is installed, and WEBLOGIC_NAME is the name of the server instance within WebLogic.
Essbase Administration Server log files record all requests received from clients (Administration Services Console) and indicate whether requests were successful. Log files are not cleared when Essbase Administration Server is shut down. You must control log file size manually.
