Log4j2 overwrites past day log file

Question

I\'m using Log4j2 ver 2.3

log4j2.xml looks like:

Answer 1

Log4j 2.3 is somewhat old, being released on 2015-05-09, almost 3 years old. So try using a updated version; version 2.11.0 is the latest as of now which was released on 2018-03-11.

Update: To continue using Log4j 2.3, you can compromise your requirements. One of the options could be using static value for fileName attribute. E.g. .../catalina.log, .../catalina.current.log, etc.

Answer 2

try

BasicConfigurator.resetConfiguration()

in the method that uses logger after BasicConfigurator.configure()

Answer 3

Try adding an auto-increment variable to your file pattern (%i). This worked fine for me.

filePattern="${sys:catalina.base}/logs/catalina.%d{yyyy-MM-dd}.%i.log"

Answer 4

mention in time based TimeBasedTriggeringPolicy time interval as 1 it will rollover file on daylly basis
