Maximum File Size - supported in log4j FileAppender
file, file-io, fileappender, log4j, log4j2
Solution
By default, maximum file size is `10MB`(If you don't mention explicitly). And if you define explicitly, you can define any value upto `GB`(even 1000GB). But think, when you open this file, your machine must have an equal amount of `RAM`. So you have to take this into consideration before choosing `file size`. An example here
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logging.log
log4j.appender.file.MaxFileSize=100GB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
`FileAppender` doesn't contain any field for setting file size. But its subclasses `RollingFileAppender` and `DailyFileAppender` contains.
Problem
I have a requirement that I need to store audit information in a TEXT file. I planned to write the audit information using `Apache Log4j`. Seems to be reliable option. But, I should be able to write the Audit information even the fileSize reaches 3GB. Does the `log4j` supports the fileSize even at `GigaBytes`?. Or with a Quick Question, What is the `MaximumFileSize` can be supported in `Log4j`. NOTE : I could not go for RollingFileAppender or DailyFileAppender, I need to log the information Only in One text file, where some other components are reading this file content and doing some process.
