log-conf.xml

The log-conf.xml file is included with the Data Loader installer version 35.0 and later. To change the location of the log-conf.xml file, specify the full path, incuding the full file name, in the LOG4J_CONFIGURATION_FILE environment variable.

In Windows, the log-conf.xml file is at C:\Users\{userName}\dataloader\version\configs
In macOS, the log-conf.xml file is at /Users/{userName}/dataloader/version/configs

Configure Log Levels

Change @LOG_LEVEL@ to TRACE, DEBUG, INFO, WARN, ERROR, or FATAL for the needed level of log tracking. For Log4J log levels, see https://logging.apache.org/log4j/2.0/manual/architecture.html.

To implement enhanced logging, use a copy of log-conf.xml.
