Configure the Data Loader Log File

You can customize the Data Loader log file for advanced troubleshooting and tracking.
Available in: both Salesforce Classic (not available in all orgs) and Lightning Experience
Available in: Enterprise, Performance, Unlimited, and Developer editions

The log-conf.xml file is included with the Data Loader installer version 35.0.
  • 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

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.
