The only thing I can think of that will be a bit odd, is to have two different logs, both having INFO messages with one being a superset of the other. We could add a new marker INFO-VERBOSE, that is logged asynchronously to verbose-system.log (former debug.log) - all other INFO/WARN/ERROR logs would only go to system.log. Admins would typically only look at system.log, and only go to verbose-system.log when facing problems, troubleshooting issues or wanting to perform advanced tuning, etc. Ultimately advanced operators could still disable the system-verbose.log if/when they're not interested in that. was (Author: pauloricardomg): bq.

Debug logging would still exist and be disabled by > default and the root logger level (not just filtered at the appender level). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
