Question

is there any documentation that while i am using the log4j, what will be the file extension

    #Normal Log File

log4j.appender.logfile.File=/logs/apps/application.txt
log4j.appender.logfile.MaxFileSize=100KB

log4j.appender.logfile.layout.ConversionPattern=%d [~C | ~N | ~S] %-5p (%F:%M():%L)  - %m%n

any specific extension or i can use extension like .txt , .log, .out etc ....

Answer 1

I think you can use any extension file based on your preference. Based on your configuration when it reach 100KB the file will rotate to application.txt.1 . log extension is preferable since the purpose of the file is for logging
