Zabbix template to monitor many common mailserver services

About

This is a simple template for the Zabbix monitoring server. It was created under version 4.2.1, but it may run with earlier versions as well.

The python script discovers a lot of common services on your mail server and creates items and triggers for each and any service it found. Normally the discover process runs every 12 hours, while the checks are down every 30 seconds.

Installation

Copy the python script to /usr/local/bin. Make sure, you have at least Python 3.x installed.

You can edit this file for your needs. The simplest way is to add all your favorite services to the Enum called "Services". If you look at the code, you will see that this is not a big deal, even if you are not a developer.

In Zabbix add the template as usual. After that, you can directly add the template to your host(s).

The template provides a macro

MAILSERVER_IP = 127.0.0.1

It scanns all services on the local IPv4 loopback interface. If you want to scan more than one IP address, simply override the macro and set all your hosts as a space seperated list. Also IPv6 is supported. Please no not add brackets to these addresses.

This is an example from my server:

MAILSERVER_IP = 127.0.0.1 134.255.226.248 2a05:bec0:28:1:134:255:226:248```

Place the userparameter_mailserver.conf file in your zabbix-agent include folder. Mostly it has a name like

/etc/zabbix/zabbix_agentd.d

Here is some example of a graph:

As I am running the service under Gentoo, I can not provide a working SELinux policy yet. This may be added at a later time.
