Microsoft Exchange Server 2016 by Zabbix agent

Overview

Official Template for Microsoft Exchange Server 2016.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • Microsoft Exchange Server 2016 CU18

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Metrics are collected by Zabbix agent.

1. Import the template into Zabbix.

2. Link the imported template to a host with MS Exchange.

Note that template doesn't provide information about Windows services state. Recommended to use it with "OS Windows by Zabbix agent" template.
