Hello @bmahajan ,

To capture these in Log4J you would pass a command line VM argument, for example:

-Djava.util.logging.config.file=.\logging.properties

With your custom logging.properties file defining how you wish to log into a file.

I use the following logging.properties file that I put in the same directory and that was at some point adapted from an online sample. It logs timestamped, into emaj.log.X files:

#This file contains log configuration for java logging API
.level=INFO
 
handlers=java.util.logging.FileHandler, java.util.logging.ConsoleHandler
#handlers=java.util.logging.ConsoleHandler

java.util.logging.ConsoleHandler.level=WARNING
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
 
java.util.logging.FileHandler.level=FINEST
java.util.logging.FileHandler.pattern=.\emaj.log
 
# Write 100000 bytes before rotating this file
java.util.logging.FileHandler.limit=50000000
 
# Number of rotating files to be used
java.util.logging.FileHandler.count=20
java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
# Format timestamp as date/time with millisecond
java.util.logging.SimpleFormatter.format=%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS.%1$tL %4$-7s %2$s %n%5$s

For mode details on Log4J properties spec, and examples, there are many relevant online resource, such as:
