Firefly Luciferin logs are stored in:
Windows: ~\Documents\FireflyLuciferin\logs
Linux: $XDG_CONFIG_HOME/FireflyLuciferin/logs

To enable debug mode, edit the configuration file located in the same folder as the log files.

At the bottom of the file, locate the following line:
extendedLog: "INFO"
and change it to:
extendedLog: "DEBUG"

Then restart Firefly Luciferin.
The detailed logs will be available in the same logs folder.

Supported log level are:

  • TRACE: The TRACE Level designates finer-grained informational events than the DEBUG.
  • DEBUG: The DEBUG Level designates fine-grained informational events that are most useful to debug an application.
  • INFO: The INFO level designates informational messages that highlight the progress of the application at coarse-grained level. (This is the DEFAULT log level)
  • WARN: The WARN level designates potentially harmful situations.
  • ERROR: The ERROR level designates error events that might still allow the application to continue running.
  • FATAL: The FATAL level designates very severe error events that will presumably lead the application to abort.
  • ALL: The ALL has the lowest possible rank and is intended to turn on all logging.
  • OFF: The OFF has the highest possible rank and is intended to turn off logging

Alternatively, the log level specified in the configuration file can be overridden by setting the LUCIFERIN_LOG_LEVEL environment variable to one of the supported levels.
