16. Icinga
Icinga was originally a branch of Nagios. Icinga 2 is subtracted and provides distributed monitoring and multithreading frameworks that Nagios or Icinga 1 do not have. You can migrate from Nagios to Icinga 1 and then Icinga 2.
Like Nagios, Icinga can be used on almost any device, and works best with SNMP, custom plug-ins, and extensions.
Icinga provides a global monitoring and warning framework, just different from Nagios on the Web UI.
Icinga has a variety of Web UIs, and the main difference with Nagios is configuration, which users can do through the Web UI, eliminating troublesome configuration documents. This is a major benefit for those who manage configuration outside of the command line.
Icinga incorporates several mapping and monitoring kits (PNP4Nagios, inGraph and Graphite), which are absolutely reliable for visualization. Icinga also has extended reporting capabilities.
17. Ntop
The Ntop project, also known as Ntopng, has been in development on and off for a decade. It is a top network traffic monitoring tool, the Web graphical user interface is simple and smooth. It’s written in C and completely independent, and you just run the configuration to monitor a single process for a particular network interface, and that’s it.
Ntop provides easy-to-understand graphs and tables showing current and past network traffic, including protocols, sources, destinations, and histories of specific transactions, and even hosts at both ends. In addition, you’ll find extensive network utilization charts, real-time maps and trends, as well as plug-in frameworks for various add-ons such as NetFlow and sFlow. There is even a dedicated hardware monitor, Nbox, embedded in Ntop.
Ntop even uses the lightweight Lua API framework to support extensions through the scripting language. Ntop can also store host data in RRD files to support persistent data collection.
The most convenient use of Ntop is for field flow checks. When you notice that one of your Cacti PHP Weathermaps suddenly shows a red set of web links, that means the links are over 85% utilized, but you don’t know why. By switching to the Ntopng program to monitor that network segment, you can view the report of the highest traffic consumer per minute and immediately know which host is hogging traffic.
That visibility is priceless, and it’s easy to get. Essentially, you can run Ntopng on any port configured at the switch level to monitor any port or VLAN.
