Nagios Core - Performance Graphs Using PNP4NagiosThis documentation explains how to configure Nagios Core to use the PNP4Nagios program to generate performance graphs.When Nagios Core receives check results from Host and Service checks, the check result can include performance data. This performance data needs to be specifically formatted as per the following guidelines:Nagios Plugins Development Guidelines - Performance DataNagios Core does not have it's own performance data engine built in to process this performance data, instead it provides functionality to pass this performance data to an external program that can store that data for later analysis.PNP4Nagios is one such external program. PNP4Nagios provides the following functionality:Process and store the received performance data in Round Robin Database (RRD) filesA GUI to display the data in the RRD files from within the Nagios Core interfaceDO NOT follow this guide if you are using Nagios XI. Nagios XI includes a specific version and configuration of PNP4Nagios and following this guide will result in breaking your Nagios XI installation.This guide is broken up into several sections and covers different Linux distributions and operating systems (OS). If your Linux Distribution or operating system is not included in this guide then please contact us to see if we can get it added. Some distributions may be missing as we don't have access to a test environment that allows us to develop the documentation.PNP4Nagios 0.6.26 running on Nagios Core 4.4.3 is what this guide instructs you to install, however future versions should also work fine with these steps.Note: This guide is based on Nagios Core being installed using the following KB article:Documentation - Installing Nagios Core From SourceBecause this guide is based on Nagios Core already being installed, prerequisites like Apache and PHP will already be installed on the Nagios Core server, they will only be re-installed if your OS requires that to enable a module.Please select your OS:Red Hat Enterprise Linux (RHEL)CentOSOracle LinuxUbuntuSUSE SLES | openSUSE LeapDebianRaspbianFedoraArch LinuxGentooFreeBSDRHEL | CentOS | Oracle LinuxPrerequisitesPerform these steps to install the pre-requisite packages.===== RHEL 5 | CentOS 5 | Oracle Linux 5 =====yum install -y rrdtool perl-rrdtool php-gdcpan -f -i Time::HiRes If CPAN has not been run before you will need to answer a series of questions, usually accepting the default choice using Enter will suffice.===== RHEL 6/7 | CentOS 6/7 | Oracle Linux 6/7 =====yum install -y rrdtool perl-rrdtool perl-Time-HiRes php-gd===== RHEL 8 =====dnf install -y rrdtool perl-rrdtool
