Stdout log format about tomcat-slf4j-logback HOT 1 CLOSED

You don't on ones going to stdout/stderr as those are not controlled by tomcat nor logback. You would need to write your own collector and attempt to redirect that output. I've done such a thing but its not very useful as any library can simply change the redirect. For the ones that are controlled, you set then in the logback.xml file as you see in your example and follow directions at logbacks website for configuration of the file. The bit that ships with this is just emulating as closely to how tomcat works out of the box as possible.
