When I try to see the Zimbra statistic in the control panel, got the error messages like this …
Message: system failure: Unable to read logger stats Error code: service.FAILURE Method: GetLoggerStatsRequest Details:soap:Receiver
It seems the problems with Logger services. Trying to fix it by myself, it doesn’t work at all. Then see in the Zimbra forums, got if I need to install rsyslog.
# apt-get install rsylog
Then as root:
# su - zimbra
at Zimbra-Sheel $ zmcontrol stop
at Zimbra-Sheel $ zmcontrol start
Well, at least it fixes my issues.
