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 ~]$


Note: Do not change default date/time format template in RSYSLOG configuration

Sites using rsyslog should make sure "$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat" is included in rsyslog.conf. This changes the timezone format from rsyslog's default to the standard syslog format. If this is not set, the logger systems will not be able to parse the syslog data correctly, and message traffic data will not appear and Admin Console will show "services are not running" for all services.
