First, Know What OS Logger Service Your Using

Options might be: rsyslog, syslog-ng, or syslog . The steps below will differ depending on the OS logger service your using.

Should be easy as doing [Example is from Centos test box] :

[zimbra@mail-172 ~]$ ps -ef | grep syslog
root      1299     1  0 May15 ?        00:01:14 /sbin/rsyslogd -i /var/run/syslogd.pid -c 5
zimbra   19789 13112  0 10:42 pts/1    00:00:00 grep syslog
[zimbra@mail-172 ~]$ ls /etc/sysconfig/*log*
/etc/sysconfig/mcelogd  /etc/sysconfig/rsyslog

Below are the steps to configure logger monitor host in ZCS multi-server setup

Note: run below steps in non-peak hours during scheduled downtime.

Run on logger monitor Host:

su - zimbra
zmcontrol stop ; exit

Run as root user

/opt/zimbra/libexec/zmfixperms -e -v

On the logger monitor host, you must enable syslog to log statistics from remote machines

 a. Edit the /etc/sysconfig/syslog file (if using rsyslog, then Edit the /etc/sysconfig/rsyslog file), add -r to the SYSLOGD_OPTIONS setting,  SYSLOGD_options=”-r -m 0”
 b. /opt/zimbra/libexec/zmsyslogsetup 
 b. Stop the syslog daemon. Type /etc/init.d/syslogd stop.
 c. Start the syslog daemon. Type /etc/init.d/syslogd start.


If You are using rsyslog instead of syslog, then you will need below change in rsyslog config.

we need to enable a module for remote logging in logger host, below changes fixes this issue.

We need to edit the rsyslog config file "/etc/rsyslog.conf" and enable "imudp" module by uncommenting the same.

$ModLoad imudp
$UDPServerRun 514

After the above change restart rsyslog service.

su - zimbra 
zmcontrol start 
/opt/zimbra/libexec/zmloggerinit 
/opt/zimbra/bin/zmsshkeygen
/opt/zimbra/bin/zmupdateauthkeys 

Verify the LogHostname using below commands. (it should be set to name of logger monitor host on all servers)

zmprov gacf |grep zimbraLogHostname

If its different, change the same to logger monitor hostname using below command.

zmprov mcf zimbraLogHostname <Logger monitor Hostname>

On all other servers: (if you have multiple zimbra servers in your setup)

Verify the LogHostname using below commands. (it should be set to name of logger monitor host on all servers)

su - zimbra
zmprov gacf |grep zimbraLogHostname  

If its different, change the same to Logger monitor Host using below command.

zmprov mcf zimbraLogHostname <Logger monitor Hostname>
/opt/zimbra/bin/zmsshkeygen
/opt/zimbra/bin/zmupdateauthkeys ; exit
/opt/zimbra/libexec/zmsyslogsetup (run as root user)
service syslog restart
service rsyslog restart
su - zimbra
zmcontrol restart


If the above steps didn't help you to resolve the issue, then try deleting old logger host map & create a new logger host map using below script.

/opt/zimbra/bin/zmloggerhostmap -h

Usage: zmloggerhostmap [-adh] <dns_hostname> <zm_hostname>

 -a        - create a new host mapping
 -d        - delete a host mapping (specify both names to prevent accidents)
 -h        - show this help


Example:

[zimbra@zcs8 ~]$ hostname -f
zcs8.zcsvin.com
[zimbra@zcs8 ~]$ zmhostname
zcs8.zcsvin.com
[zimbra@zcs8 ~]$ /opt/zimbra/bin/zmloggerhostmap -a zcs8.zcsvin.com zcs8.zcsvin.com 2>&1
Added mapping for zcs8.zcsvin.com to zcs8.zcsvin.com
[zimbra@zcs8 ~]$
