Custom log levels can be defined in code or in configuration. To define a custom log level in code, use the Level.forName() method. This method creates a new level for the specified name. After a log https://logging.apache.org/log4j/2.x/manual/customloglevels.html level is defined you can log messages at this level by calling the Logger.log() method and passing the custom log level: // This creates the "VERBOSE" level if it does not exist yet. final Level VERBOSE = Level.forName("VERBOSE", 550); final Logger logger = LogManager.getLogger(); logger.log(VERBOSE, "a verbose message"); // use the custom VERBOSE level // Create and use a new custom level "DIAG". logger.log(Level.forName("DIAG", 350), "a diagnostic message"); // Use (don't create) the "DIAG" custom level. // Only do this *after* the custom level is created! logger.log(Level.getLevel("DIAG"), "another diagnostic message"); // Using an undefined level results in an error: Level.getLevel() returns null, // and logger.log(null, "message") throws an exception. logger.log(Level.getLevel("FORGOT_TO_DEFINE"), "some message"); // throws exception! When defining a custom log level, the intLevel parameter (550 and 350 in the example above) determines where the custom level exists in relation to the standard levels built-in to Log4J 2. For reference, the table below shows the intLevel of the built-in log levels. Standard log levels built-in to Log4J Standard Level intLevel OFF 0 FATAL 100 ERROR 200 WARN 300 INFO 400 DEBUG 500 TRACE 600 ALL Integer.MAX_VALUE Defining Custom Log Levels in Configuration Custom log levels can also be defined in configuration.

The set of possible levels, that is DEBUG, INFO, WARN, ERROR and FATAL are http://stackoverflow.com/questions/19678324/trace-log-level defined in the org.apache.log4j.Level class. If a given logger is not assigned a level, then it inherits one from its closest ancestor with an assigned level. log level The root logger resides at the top of the logger hierarchy. It always exists and always has an assigned level. The logger is the core component of the logging process. In log4j, there are 5 normal levels Levels of logger available (not including custom Levels), the following is borrowed from the log4j log4j trace debug API (http://jakarta.apache.org/log4j/docs/api/index.html): 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. WARN - The WARN level designates potentially harmful situations. ERROR - The ERROR level designates error events that might still allow the application to continue running. TRACE - The TRACE Level designates finer-grained informational events than the DEBUG FATAL - The FATAL level designates very severe error events that will presumably lead the application to abort. In addition, there are two special levels of logging available: (descriptions borrowed from the log4j API http://jakarta.apache.org/log4j/docs/api/index.html): ALL -The ALL Level has the lowest possible rank and is intended to turn on all logging. OFF - The OFF Level has the highest possible rank and is intended to turn off logging. source: http://www.allapplabs.com/log4j/log4j_levels.htm http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html 赞过:赞 正在加载…… 相关 发表在 Uncategorized | Ta

Is this old Log4J library and TRACE appears only in some new one? java log4j share|improve this question asked Oct 30 '13 at 9:24 vico 2,65063571 Its between ALL and DEBUG. –Peter Lawrey Oct 30 '13 at 9:30 @user1501700 You need to update the version in order to get the TRACE level. –Paul Vargas Oct 30 '13 at 13:06 @user1501700 You forgot to upvote. Also accept an answer. –Paul Vargas Oct 30 '13 at 23:26 add a comment| 3 Answers 3 active oldest votes up vote 6 down vote Log4j itself does not have the TRACE level. That log level is provided by the newer logging facades like commons-logging or slf4j. These facades itself do not log but delegate to underlying logging providers like log4j or logback. share|improve this answer answered Oct 30 '13 at 9:32 Vrushank 1,56411432 add a comment| up vote 5 down vote The org.apache.log4j.Level.TRACE level was added to log4j in the version 1.2.12 You need to update the version of your log4j's library. share|improve this answer edited Jan 8 '15 at 17:19 answered Oct 30 '13 at 13:05 Paul Vargas 22.9k65079 in Log4J, see org.apache.log4j.Level, ALL=TRACE=DEBUG syslogEquivalent is 7 –feilong Jun 26 at 6:35 add a comment| up vote 1 down vote you have to mention it on your
