App A uses log4j2 logs to files. It's not too much data. I want to do what
chain saw does but without the UI. I want to read the log file. Get the
info back as a java objects. Then process them. Many lines are multiline.
So don't want to write this code my self. Yes I want the object back I'm on
my App B for further processing. APP A has many flavours with different
log4j2 config files with different patterns. But all writing to file system.
Just not sure what code parses lines from a log to create a log event in
Java?
Thank you for your time.
