Welcome to the forums!
Likely syslogging is not working for you; please check if /var/log/zimbra*.log are being populated with data. If not, check if your RH syslog service is running and whether Zimbra stats is running.
A search here will yield lots of threads as to how to tackle various syslog issues; there are several flavors of problems.
Hope that helps,
Mark
