Description
I read JEP-158 again, here is the statement:
"Logging can be configured dynamically at runtime via jcmd or MBeans"
Currently, dcmd can change tags and decorators on the fly.
eg. The following command affects log output #2, which is file=gc.log
jcmd 120863 VM.log output=file=gc.log what='all=off,logging+thread=debug,gc=debug' decorators=t,tid,l,tags
dmcd can use 'what' and 'decorators' to change log selections and decorators. those things are changeable for an established log output.
This feature is supported well by synchronous logging. Currently, it's not MT-safe in async mode.
