2.4.1. About Log Levels
Log levels are an ordered set of enumerated values that indicate the nature and severity of a log message. The level of a given log message is specified by the developer using the appropriate methods of their chosen logging framework to send the message.
JBoss Data Grid 6 supports all the log levels used by the supported application logging frameworks. The six most commonly used log levels are (ordered by lowest to highest):
TRACEDEBUGINFOWARNERRORFATAL
Log levels are used by log categories and handlers to limit the messages they are responsible for. Each log level has an assigned numeric value which indicates its order relative to other log levels. Log categories and handlers are assigned a log level and they only process log messages of that level or higher. For example a log handler with the level of
WARN will only record messages of the levels WARN, ERROR and FATAL.
