How to monitor messages statistics of Zimbra mail server
Zimbra provides monitoring that helps us check system status and performance effectively. However, it lacks monitoring of email sending and receiving statistics. This information would help administrators spot delivery anomalies promptly, such as a leaked password allowing a spammer to send a huge volume of mail through the system, creating a risk of blacklisting.
Configuring the system to Monitor messages statistics
-
Install logcheck.
[root@EzyMailHosting ~]# yum install logcheck -
Create zabbix-postfix.sh in /opt with the following contents.
#!/bin/bash MAILLOG=/var/log/maillog DAT1=/tmp/zabbix-postfix-offset.dat DAT2=/tmp/zabbix-postfix-offset-2.dat PFLOGSUMM= /opt/zimbra/libexec/pflogsumm.pl ZABBIX_CONF=/etc/zabbix/zabbix_agentd.conf RESULT_STATUS=/tmp/tmp_postfix_result /usr/sbin/logtail -f$MAILLOG -o$DAT1 | $PFLOGSUMM -h 0 -u 0 --no_bounce_detail --no_deferral_detail --no_reject_detail --no_no_msg_size --no_smtpd_warnings > $DAT2 echo "- postfix.received `grep -m 1 received $DAT2|cut -f1 -d"r"`" > $RESULT_STATUS echo "- postfix.delivered `grep -m 1 delivered $DAT2|cut -f1 -d"d"`" >> $RESULT_STATUS echo "- postfix.forwarded `grep -m 1 forwarded $DAT2|cut -f1 -d"f"`" >> $RESULT_STATUS echo "- postfix.deferred `grep -m 1 deferred $DAT2|cut -f1 -d"d"`" >> $RESULT_STATUS echo "- postfix.bounced `grep -m 1 bounced $DAT2|cut -f1 -d"b"`" >> $RESULT_STATUS echo "- postfix.rejected `grep -m 1 rejected $DAT2|cut -f1 -d"r"`" >> $RESULT_STATUS echo "- postfix.rejectwarnings `grep -m 1 "reject warnings" $DAT2|cut -f1 -d"r"`" >> $RESULT_STATUS echo "- postfix.held `grep -m 1 held $DAT2|cut -f1 -d"h"`" >> $RESULT_STATUS echo "- postfix.discarded `grep -m 1 discarded $DAT2|cut -f1 -d"d"`" >> $RESULT_STATUS echo "- postfix.bytesreceived `grep -m 1 "bytes received" $DAT2|cut -f1 -d"b"`" >> $RESULT_STATUS echo "- postfix.bytesdelivered `grep -m 1 "bytes delivered" $DAT2|cut -f1 -d"b"`" >> $RESULT_STATUS /usr/bin/zabbix_sender -c $ZABBIX_CONF -i $RESULT_STATUS rm $DAT2 -
Add the following cron entry so the script sends statistics to the ZABBIX server.
