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.

AlertSite

AlertSite works exceptionally well if you need to analyze how your digital assets perform over time and, based on provided reports, determine the potential slow down root cause to make data-driven decisions instantly. In case you are used to analyzing by visually representing your availability and performance, AlertSite might not be the perfect solution for you.

AlertSite

  • The Deja-Click Recorder is an excellent tool.
  • Good UI that translates to large NOC screens well.
  • Easy Alerting and Reporting.

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.

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.

What we have noticed so far is the fact that AlertSite customer support team is trying to build relationships and go the extra mile to make sure we can overcome any occurring issues. They are quick to respond and provide sufficient guidance about how to implement product features efficiently, integrate new tools, and fix product issues.

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.

We moved all of our services to Site24x7 after several years with AlertSite. We looked at Uptrends and Pingdom to name a few whilst evaluating options. Pingdom lacks functionality and Uptrends we found to have quite a steep learning curve. AlertSites platform and in particular the Deja-Click recorder is a standout tool against the other platforms. Sadly the upscaling costs of multi-location transactions can quickly add up.

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

AlertSite

  • Creating complex web monitor scripts in just a few clicks reduced time to create monitoring improvements.
  • AlertSite Single Sign-On feature reduced integration costs.
