Hello, Several times I've been in a situation where in a given JVM I am trying to run distinct jobs in separate threads, who themselves might spawn their own threads. In those situations I usually want the logging of each job in a separate log file, and that has proven to be difficult.
Log4j2 has a routing appender that allows to create a separate appender for each job given that you can provide a routing key that's unique for each job. But what key to use for this? I've been using a ThreadContext variable that I set at the level of the job thread, and any child thread that I have control over. But the problem is that I don't always have control over this. Sometimes third party APIs let you feed a custom ThreadFactory, sometimes they don't. When they don't, I can't set that ThreadContext variable and part of the job logging will be misrouted to a different appender. Is there a way to work around this so that there is 1 log file for each job that would gather all the logging of the sub threads? Thanks, Benjamin
