You may have been involved in the design and implementation of a network or maybe you came on-board after the network had been built. No matter the case, one thing that becomes quickly apparent is that there is a need to make sure the network is operating as it should and one of the ways to ensure that is Monitoring. Network Monitoring gives administrators a clear view of the devices, services, applications running on their network and the opportunity to track the availability/performance of these resources.

Alerts could be sent via SMS, Email, etc.
• Graphs: Knowing the current status of a resource is good but even more beneficial is being able to see that status over time. Such information is best displayed in graphs and most monitoring tools provide various graphs for monitored parameters. • Reports: Reports are not only important for administrators but also for management.

Network monitoring tools can be categorized in several ways, from those that only work on Windows systems to those that require a paid license to operate.

Note: Nagios comes in two flavours: (which is free and open source) and (paid Enterprise edition). Since this article is about open source network monitoring tools, we will focus on Nagios Core. By default, all the configuration (e.g. Adding hosts and services to be monitored) for Nagios is done through text files. This can take some time to get used to resulting in a steep learning curve and thus, reduces its attractiveness to new users.
