Nagios, which runs under Linux, is a popular open source host, service and network monitoring program that helps streamline network-monitoring tasks while reducing the cost of operation. According to the Nagios project site, Nagios is currently in use monitoring more than 907,526 services and 198,783 hosts worldwide

Nagios has the ability to monitor network services (SMTP, POP3, HTTP, NNTP, PING, etc.), host resources (processor load, disk and memory usage, etc.), and environmental factors such as temperature, in addition to other features. Nagios helps users simplify the complicated but necessary task of monitoring the health of the devices and services in an IT infrastructure, but a lot of people don’t know how to properly use Nagios effectively.

In this session, Dondich will discuss the basics of installing, configuring, and using Nagios for those who are new to the tool as well as touch on ways to extend the functionality of Nagios for those who are already familiar with the product.
