Steps for installing nagios and pnp4nagios in centos

I. INTRODUCTION

Nagios is an open-source computer system and network monitoring tool that can effectively monitor the status of Windows, Linux and Unix hosts, network settings such as vswitches and routers, and printers. It's a powerful O & M tool, but not nagios. How can you say that you are an O & M engineer?

II. Install nagios

1. Download nagios: Download Address: http://sourceforge.net/projects/nagios-cn? Source = typ_redirect

It should be enabled by default:

I have no problem. If there is an error, most of them will be missing some packages. Check it online.

By now, more than half of the success has been achieved.

Install nagios-plugins and nrpe

Download nagios-plugins: http://nagios-plugins.org/download/nagios-plugins-2.0.3.tar.gz

Then let's talk about how to install pnp4nagios:

1. Download https://sourceforge.net/projects/pnp4nagios/files/latest

2. Compile and install:

Tar zxvf pnp4nagios-0.6.14.tar.gz
Cd pnp4nagios-0.6.14
./Configure & make all & make install
Enable nagios. cfg configuration:
Host_perfdata_command = process-host-perfdata
Service_perfdata_command = process-service-perfdat

Modify commands. cfg configuration:

Define command {
Command_name process-host-perfdata
Command_line/pnp4nagios/libexec/process_perfdata.pl-d HOSTPERFDATA
        }
 
 
# 'Process-service-perfdata' command definition
Define command {
Command_name process-service-perfdata
Command_line/pnp4nagios/libexec/process_perfdata.pl
        }

Add the corresponding action_url in templates. cfg:

Host Template

Action_url/pnp4nagios/index. php/graph? Host = $ HOSTNAME $ & srv = _ HOST _

Service Template
Action_url/pnp4nagios/index. php/graph? Host = $ HOSTNAME $ & srv = $ SERVICEDESC $

Well, little sun is coming.
