Specifies the overall log level for all modules. The syntax is:

gg.log.level={ERROR|WARN|INFO|DEBUG}

The log levels are defined as follows:

• ERROR – Only write messages if errors occur

• WARN – Write error and warning messages

• INFO – Write error, warning and informational messages

• DEBUG – Write all messages, including debug ones.

The default logging level is INFO. The messages in this case will be produced on startup, shutdown and periodically during operation. If the level is switched to DEBUG, large volumes of messages may occur which could impact performance. For example, the following sets the global logging level to INFO:

# global logging level
gg.log.level=INFO
