DELL PowerEdge R740 by HTTP

Overview

This is a template for monitoring DELL PowerEdge R740 servers with iDRAC 8/9 firmware 4.32 and later with Redfish API enabled via Zabbix HTTP agent that works without any external scripts.

Requirements

Zabbix version: 7.2 and higher.

Tested versions

This template has been tested on:

  • DELL PowerEdge R740

Configuration

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

Setup

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

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

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

4. Link the template to the host.

5. Customize values of {$API.URL}, {$API.USER}, {$API.PASSWORD} macros.

Macros used

Name Description Default
{$API.URL}

The Dell iDRAC Redfish API URL in the format <scheme>://<host>:<port>.

 <Put your URL here>
{$API.USER}

The Dell iDRAC username.

 <Put your username here>
{$API.PASSWORD}

The Dell iDRAC user password.

 <Put your password here>
{$IFCONTROL}

Link status trigger will be fired only for interfaces that have the context macro equaled 1.

{#IFNAME} Link down

This trigger expression works as follows:
1. It can be triggered if the operations status is down.
2. {$IFCONTROL:"{#IFNAME}"}=1 - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
3. {TEMPLATE_NAME:METRIC.diff()}=1 - the trigger fires only if the operational status was up to (1) sometime before (so, do not fire for the 'eternal off' interfaces.)

WARNING: if closed manually - it will not fire again on the next poll, because of .diff.
