# DELL PowerEdge R750 by SNMP

## Overview

This is a template for monitoring DELL PowerEdge R750 servers with iDRAC version 7 (and later) via Zabbix SNMP agent that works without any external scripts.

## Requirements

Zabbix version: 7.0 and higher.

## Tested versions

This template has been tested on:
- DELL PowerEdge R750xs

## 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.
