Has anyone ever gotten this to work?
I've tried ppearl's suggestions, also the information at
Ajcody-Logging - Zimbra :: Wiki, and a few ideas of my own, such as defining a separate SyslogAppender in log4j.properties.in which points directly to the centralized syslog server.
I've restarted zmconfigdctl, zmmailboxdctl, and zmloggerctl.
(I haven't restarted Zimbra.)
Now I'm thinking it may have to do with this line
log4j.additivity.zimbra.security=false
Although that doesn't quite make sense based on reading:
Apache log4j 1.2 - Short introduction to log4j Log4j Tutorial: Additivity – what and why? | Veera Sundar Log4jXmlFormat - Logging-log4j Wiki
Nope, commenting that out also doesn't do any good.
