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 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 R740

Configuration

Zabbix should be configured according to the instructions in the 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.

Macros used

Name Description Default
{$DELL.HTTP.API.URL}

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

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

The Dell iDRAC username.

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

The Dell iDRAC user password.

 <Put your password here>
{$DELL.HTTP.PROXY}

Set an HTTP proxy for Redfish API requests if needed.
{$DELL.HTTP.RETURN.CODE.OK}

Set the HTTP return code that represents an OK response from the API. The default is "200", but can vary, for example, if a proxy is used.

 200
{$DELL.HTTP.REQUEST.TIMEOUT}

Set the timeout for HTTP requests.

 10s
{$DELL.HTTP.IFCONTROL}

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

 1
{$DELL.HTTP.CPU.UTIL.HIGH}

Sets the percentage threshold for creating a "high" severity event about CPU utilization.

 90
{$DELL.HTTP.CPU.UTIL.WARN}

Sets the percentage threshold for creating a "warning" severity event about CPU utilization.

 75
{$DELL.HTTP.MEM.UTIL.HIGH}

Sets the percentage threshold for creating a "high" severity event about memory utilization.

 90
{$DELL.HTTP.MEM.UTIL.WARN}

Sets the percentage threshold for creating a "warning" severity event about memory utilization.

 75
{$DELL.HTTP.IO.UTIL.HIGH}

Sets the percentage threshold for creating a "high" severity event about IO utilization.

 90
{$DELL.HTTP.IO.UTIL.WARN}

Sets the percentage threshold for creating a "warning" severity event about IO utilization.

 75
{$DELL.HTTP.SYS.UTIL.HIGH}

Sets the percentage threshold for creating a "high" severity event about SYS utilization.

 90
{$DELL.HTTP.SYS.UTIL.WARN}

Sets the percentage threshold for creating a "warning" severity event about SYS utilization.
