Confirm the logger package is installed on the machine:
rpm -qa | grep zimbra-logger
or
dpkg --list | grep zimbra-logger
See if the ZCS setup has logger installed:
zmprov gs `zmhostname` | grep zimbraServiceInstalled
If the logger services shows installed, you can run:
zmprov ms `zmhostname` -- +zimbraServiceEnabled logger
~/zmmtaconfig logger
You may need to restart logger by hand:
zmloggerctl start |
