# DELL PowerEdge R750 by HTTP

## Overview

This is a template for monitoring DELL PowerEdge R750 servers with iDRAC 8/9 firmware 4.32 (and later) with Redfish API enabled via Zabbix script items. This template works without any external scripts.

## Requirements

Zabbix version: 7.4 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/7.4/manual/config/templates_out_of_the_box) section.

## Setup

1\. Enable Redfish API in the Dell iDRAC interface of your server.

2\. Create a user for monitoring with read-only permissions in the Dell iDRAC interface.

3\. Create a host for Dell server with iDRAC IP as the Zabbix agent interface.

4\. Link the template to the host.

5\. Customize the values of the `{$DELL.HTTP.API.URL}`, `{$DELL.HTTP.API.USER}`, and `{$DELL.HTTP.API.PASSWORD}` macros.

> NOTE! If you are experiencing timeouts on some of the items that are executing requests, adjust the `{$DELL.HTTP.REQUEST.TIMEOUT}` macro accordingly.
