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.

VRealize is well suited for an organization that is heavily invested in the VMware ecosystem. There are a ton of plugins and management packs that will allow you to integrate with just about every major area of your infrastructure whether its storage, backup, cloud, or monitoring related. It is less appropriate for a company that does not already have a financial licensing agreement with VMware already established as it can be very expensive if paid for a la carte.

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.

The support is pretty good however some of the KB articles still reference different versions of the product so it can be hard to find answers to common questions

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.

We are a VMware shop and need monitoring from VMware. Also, I am not the decision maker here. I believe because of being a VMware shop we choose VRO and also may be my company got a great deal. I like this product although there is a lot of stuff to improve

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

vRealize Operations

  • We believe that the ability to preplan deployments with vRealize has proven its return on investments.
  • Our troubleshooting time has been reduced with vrealize because its constantly collecting performance data. typically vrealize will tell us cause of fault before we can determine it ourselves.
