Administrator's Guide - Logging
Logging is done by Variations on the server for server startup, individual servers running, user interface actions, and scripts. Client logging is done either to a file or the console. Statistics scripts additionally use log files from Darwin Streaming Server.
Most configuration of logging done by the Variations servers can be configured in files located in conf/server/logging. Generally all that should be changed is the name of the output log file. Currently, statistics scripts depend on the user interface logs being in the default format. Client logging configuration can be done in client_console.lcf and client_file.lcf.
