Nagios Core

Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

Nmap

NMap is well suited to just about any situation, network size, or complexity. Some have brought up the point that NMap's proxy settings need work. I haven't used NMap with a proxy. NMap is my "go to" tool for a cursory security sweep. Once a problem is found, I can perform a deeper dive scan on a system or a network. I wouldn't, and don't, use NMap as my only security tool. No single tool has all the answers. For example, it is not a Wireshark in that it does not capture packets or analyze them. It is basically a port scanner, host discovery, OS detection tool.

Pros

Nagios Core

  • Monitoring of services is one of the biggest benefits for our company. Being able to respond in a timely fashion keeps business smooth.
  • Hardware and device monitoring are easy to set up with proper parameters.
  • Notification to key staff to be able to respond quickly makes issues go away faster.

Nmap

  • Nmap has a unique process of fingerprinting applications/devices to help us identify their communications patterns quicker.
  • Nmap can be used for network auditing by specifying whole subnets that you would like to scan for open/closed ports.
  • Nmap has a diverse presence and can be used from most operating systems.

Cons

Nagios Core

  • Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
  • Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

Nmap

  • Maybe take some of the features of Zenmap and bake them in?
  • Include fancy extra graphical results charts or graphs or something to show people who you want to convey info too but have no idea what Nmap is actually doing.
  • I don't really think I'd change a lot actually.

We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

There is a very large support community and a robust selection of add-ons and scripts. Once you get the use down this is one of the most powerful tools and you can find anything you are looking for as far as examples on the web. While not having official support its not lacking by any means.

Alternatives Considered

Nagios Core

I have been using Nagios for 10+ years, so I am very familiar with it. The learning curve with SolarWinds was more difficult for me to pick up than Nagios and it wasn't as easy (at first) to duplicate, edit, etc. in SolarWinds. I genuinely think Nagios is a great product for many reasons, one of which is the unbeatable price.

Nmap

NMap usually lacks the features of the other network scanners, but for a good reason: most of the other network scanners out there are using NMap as part of their system. The nature of NMap (being open-source) is that it is available for use in other applications; as a result, these other applications make use of the NMap source code.

Return on Investment

Nagios Core

  • Much better network device performance metrics allowing to troubleshoot and do before/after changes comparisons
  • Has helped us to integrate with our Service Management tool (through other 3rd party tools)
  • Important part of our overall network health dashboard providing granular details at the device level (not end-to-end performance)
  • Cost is very convenient
Manuel Ayala | TrustRadius Reviewer

Nmap

  • Positive return as it's open-source (free) on all OS's.
  • If a person is not used of the command line there are a ton of front ends that make it point-and-click so the learning curve is good. That cuts down on time and manpower.
