Am trying to build a free IP network monitoring tools using open source software

A while ago, i was tasked to develop an IP network monitoring tool for our section and today i set out to look for an appropriate solution on the internet. we already have CACTI configured to monitor our network, so my task is to look for an alternative tool that can work as a standby monitor when CACTI is off. This article is like my scratch pad in this quest.

Useful Links

1. Nice reviews on all the available open source utilities
2. Nagios + NConf

Setting Up the Server

VMware-workstation 7.1.3
Ubuntu 12.04 desktop

Server behind a proxy, add the proxy configuration in the system wide profile.

Edit these files:

gedit /etc/environment
or
gedit /etc/profile
export http_proxy=http://username:password@proxyhost:port/ 
export ftp_proxy=http://username:password@proxyhost:port/
Then test the connection:
sudo apt-get update
