I would like the start of my logs to start with the same information "java -version" provides.
On the console, "java -version" says: java version "1.8.0_20" Java(TM) SE Runtime Environment (build 1.8.0_20-b26) Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode) I cook this up manually now from system properties but it sure would be nice to ask Log4j to do it for me since 'java -version' is something I am sure we are all used to seeing. This could be done with special pre-built Message classes and % markers I can also add to the header of a file (or any) appender. I could see a: JavaShortVersionMessage and %JavaShortVersion produce: java version "1.8.0_20" JavaJreVersionMessage %JavaJreVersion produce: Java(TM) SE Runtime Environment (build 1.8.0_20-b26) JavaVmVersionMessage and %JavaVmVersion produce: Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode) In code I could say: logger.debug(new JavaShortVersionMesssage()); logger.debug(new JavaJreVersionMessage()); logger.debug(new JavaVmVersionMessage()); In a file appender I could say header="My App%n%JavaShortVersionMessage%n%JavaJreVersionMessage%n%JavaVmVersionMessage%n" Or maybe we could have someway to break a header into >1 log event.
