# F5 Big-IP by SNMP

## Overview

This template is designed for the effortless deployment of F5 Big-IP monitoring by Zabbix via SNMP and doesn't require any external scripts.

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- F5 Big-IP

## 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

Refer to the vendor documentation.
