Nagios is a powerful network monitoring tool that helps the user ensure that the critical systems, applications and services are always up and running. It provides features such as alerting, event handling and reporting. The user can set up email, SMS and printed paper alerts. Even though manual configuration might seem difficult, that setup actually makes Nagios one of the most flexible network monitors around.

Fiddler is a web debugging tool that captures HTTP traffic between chosen computers and the Internet. It allows the user to analyze incoming and outgoing data to monitor and modify requests and responses before they hit the browser. Fiddler gives extremely detailed information about HTTP traffic and can be used for testing the performance of websites or security testing of web applications.
