# Zabbix server health

## Overview

This template is designed to monitor internal Zabbix metrics on the local Zabbix server.

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- Zabbix server 7.0

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.

## Setup

Link this template to the local Zabbix server host.

### Macros used
