Following code configures a DailyRollingFileAppender −
# Define the root logger with appender file
log4j.rootLogger = DEBUG, FILE
# Define the file appender
log4j.appender.FILE = org.apache.log4j.DailyRollingFileAppender
Posted Date:- 2021-09-01 09:00:45
This indicates when to roll over the file and the naming convention to be followed. By default, roll over is performed at midnight each day.

To write your logging information into files on a daily basis, you would have to use org.apache.log4j.DailyRollingFileAppender class which extends the FileAppender class and inherits all its properties.

Once the last log file reaches the maximum size, the first log file will be erased and thereafter, all the logging information will be rolled back to the first log file.

Following code configures maximum file size before rollover −
# Set the maximum file size before rollover
log4j.appender.FILE.MaxFileSize=5KB

This property denotes the number of backup files to be created.

This is the critical size of the file above which the file will be rolled.

To write your logging information into multiple files, you would have to use org.apache.log4j.RollingFileAppender class which extends the FileAppender class and inherits all its properties.

Following syntax defines the basis logger with WARN mode turning DEBUG mode off.# Define the basis logger with appender file
log = /usr/domestic/log4j
log4j.RootLogger = WARN, FILE

A log request of degree p in a logger with degree q is enabled if p >= q. This rule is on the heart of log4j. It assumes that levels are ordered. For the same old stages, we have ALL < DEBUG < INFO < WARN < ERROR < FATAL < OFF.

OFF − The maximum viable rank and is supposed to turn off logging.
Posted Date:- 2021-09-01 08:43:37
FATAL − Designates very excessive blunders activities on the way to presumably lead the application to abort.
Posted Date:- 2021-09-01 08:41:56
ALL − All ranges such as custom levels.

public void trace(Object message) of Logger class prints messages with the level Level.TRACE.

goal − The goal may be a console, a record, or every other object depending on the appender.

layout − Appender uses the Layout objects and the conversion sample related to them to layout the logging facts.

The log4j.Houses file is a log4j configuration file which continues properties in key-fee pairs. By default, the LogManager appears for a report named log4j.Properties inside the CLASSPATH.

Following syntax defines a file appender −
# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=${log}/log.out
Posted Date:- 2021-09-01 08:36:13
Following syntax defines the root logger with appender file:
# Define the root logger with appender file
log = /usr/home/log4j
log4j.rootLogger = DEBUG, FILE
Posted Date:- 2021-09-01 08:35:22
Level Object - The Level object defines the granularity and priority of any logging information. There are seven ranges of logging defined inside the API: OFF, DEBUG, INFO, ERROR, WARN, FATAL, and ALL.
