Install nconf web interface for nagios on debian/ubuntu

Last post was about how to install nagios on debian or Ubuntu. Nagios is a famous monitoring script but problem is it is command based, however several third party web interfaces are available, one of which is nconf.

Download nconf

wget http://downloads.sourceforge.net/project/nconf/nconf/1.2.6-0/nconf-1.2.6-0.tgz
 
tar xzvf nconf-1.2.6-0.tgz -C /var/www

Change the web owner for nconf

chown -R www-data:www-data /var/www/nconf

Create a database/username/password to use for nconf, you can use phpmyadmin for this purpose if you have it install.

1. Now browse http://your_ip_address/nconf
2. Follow steps to install nconf
3. Use everything default except NAGIOS_BIN variable to /usr/sbin/nagios3

at the end it will ask you to delete following files and directories

rm -rf INSTALL INSTALL.php UPDATE UPDATE.php

Nagios configuration

Now its time to configure nagios for nconf

1. Open /etc/nagios3/nagios.cfg
2. comment out all the lines that begin with cfg_dir= or cfg_file=
3. Add following 2 lines and save file

cfg_dir=/etc/nagios3/global
cfg_dir=/etc/nagios3/Default_collector

Now create directory

mkdir /etc/nagios3/import

Nconf configuration for nagios

Open

nano -w /var/www/nconf/ADD-ONS/deploy_local.sh

and correct the following 2 paths

OUTPUT_DIR="/var/www/nconf/output"
NAGIOS_DIR="/etc/nagios3/"

Now run

chmod +x deploy_local.sh
 
./deploy_local.sh

Also go to http://your_ip_address/nconf and click on “Generate nagios config”

This command will generate an output named “NagiosConfig.tgz” in /var/www/nconf/output
Extract this and it will give you 2 directories named “global” and “Default_collector”
Copy both of them to /etc/nagios3

mv global /etc/nagios3
mv Default_collector /etc/nagios3

And we are almost done

Restart nagios

localhost:~# /etc/init.d/nagios3 restart
Restarting nagios3 monitoring daemon: nagios3
.

Add crontab

localhost:~# crontab -e
* * * * * /var/www/nconf/ADD-ONS/deploy_local.sh
