Introduction Copied

This how-to will help you monitor Zimbra 8 MailServer. This “how-to” is tested with the open source version but should work with the other versions as well.

Prerequisites Copied

Before we start there are a couple of things that needs to be working.

About Copied

This “how-to” require a plugin to be installed on the server and special sudo permissions.

Installing plugin Copied

  1. Copy this script to the folder /opt/plugins/custom on your Zimbra server.
  2. Change the permissions to 755 on the script.
  3. Modify the sudo permissions with the command visudo

    1. Add the following lines to the configuration

      %zimbra ALL=NOPASSWD:/opt/zimbra/bin/zmcontrolnobody ALL=NOPASSWD:/opt/plugins/custom/check_zmstatus.pl

      This will allow the zimbra user to execute the zmcontrol command.

    2. Save the configuration

Configure NRPE Copied

NRPE needs to be updated, either put this file under /opt/nrped.d/ or add the following commands manually

command[zimbra_clamd]=/opt/plugins/check_clamd /opt/zimbra/data/clamav/clamav.sockcommand[zimbra_lmtp]=/opt/plugins/check_smtp -H localhost -p 7025command[zimbra_spellcheck]=/opt/plugins/check_http -H localhost -p 7780command[zimbra_dns]=/opt/plugins/check_dns -H google.comcommand[zimbra_cert]=/opt/plugins/check_http -S -H localhost -C 30command[zimbra_submission]=/opt/plugins/check_smtp -H localhost -p 587command[zimbra_imaps]=/opt/plugins/check_imap -H localhost -S -p 993command[zimbra_imap]=/opt/plugins/check_imap -H localhost -p 143command[zimbra_pop]=/opt/plugins/check_pop -H localhostcommand[zimbra_pops]=/opt/plugins/check_pop -H localhost -S -p 995command[zimbra_mailq]=/opt/plugins/check_mailq -w 5 -c 10 -M postfixcommand[zimbra_services]=/usr/bin/sudo /opt/plugins/custom/check_zmstatus.plcommand[zimbra_smtp]=/opt/plugins/check_smtp -H localhost

Modify plugins settings Copied

Edit the file /opt/plugins/utils.pm on the Zimbra server, change the line

$PATH_TO_MAILQ   = "";

to

$PATH_TO_MAILQ   = "/opt/zimbra/postfix-2.11.1.2z/sbin/mailq";

Verify the path so that that it corresponds with your Zimbra installation.

This will allow the plugin check_mailq to find the path to you mail queue folder.

Add Management Pack Copied

In this Management Pack all services are defined. Add the management pack using Management pack manager under Configure.

Depending on the services you make available on you Mailserver some services perhaps needs modification.
