The Log4j logging settings are stored in the file app_data /conf/server/log4j. properties, where app_data is the application data folder. You can edit this file directly on the server or open it by clicking Settings > Logging. Note: Do not change the name and location of the server log.

By default, Log4j 2 will use the ConsoleAppender to write the log message to the console. The log record will be printed using the PatternLayout attached to the mentioned ConsoleAppander with the pattern defined as follows: %d{HH:mm:ss. SSS} [%t] %-5level %logger{36} – %msg%n.

In Log4j 2 Layouts return a byte array. This allows the result of the Layout to be useful in many more types of Appenders. However, this means you need to configure most Layouts with a Charset to ensure the byte array contains correct values. The root class for layouts that use a Charset is org.

An Appender uses a Layout to format a LogEvent into a form that meets the needs of whatever will be consuming the log event. In Log4j 1. x and Logback Layouts were expected to transform an event into a String. In Log4j 2 Layouts return a byte array.

Apache log4j supports various Layout objects, each of which can format logging data ing to various layouts. We can also create a Layout object that formats logging data in an application-specific way. All Layout objects receive a LoggingEvent object from the Appender objects.

Below is the log4j logging level order. Trace < Debug < Info < Warn < Error < Fatal. When we define logger level, anything having higher priority logs are also getting printed. For example, if logger level is INFO then debug logs will not be printed but Warn logs will be printed because of higher priority.

The set of built-in levels includes ALL, TRACE, DEBUG, INFO, WARN, ERROR, FATAL, and OFF. Log4j 2 also supports custom log levels. Another mechanism for getting more granularity is to use Markers instead. The OFF and ALL levels are not intended to be used on calls to the logging API.
