Logging

BifroMQ utilizes the standard SLF4J interface for logging purposes and selects Apache Log4j as its logging backend. The logs are organized into five distinct levels: TRACE, DEBUG, INFO, WARN, and ERROR, with INFO set as the default log level.

Log4j Configuration File

The log4j configuration file, named log4j2.xml, is located in the conf directory within the BifroMQ installation folder. This file allows for detailed customization of logging behavior, including log level settings, output formats, and file rotation policies.

Log Directories

By default, BifroMQ stores log files in the log directory found in the installation folder. If necessary, an alternative logging directory can be designated by setting the LOG_DIR environment variable.

Plugin Logging

Plugin implementors can also leverage the standard SLF4J interface for logging.
