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.

Prometheus is a monitoring engine that is ideal for improving the performance of servers, equipment or applications since it allows real-time metrics to be obtained from the data. It has its own programming language and is open source, this allows the creation of alerts that are key for diagnosing errors. In addition, when combining this solution with Grafana, incredible results are obtained since one focuses on metrics and the other on visualization, and the union of both provides high-level metrics that are easy to visualize. Prometheus is a convenient and essential tool for monitoring, tracing and troubleshooting system health and catching bottlenecks before they become critical.

  • The response capacity of this program is incredible, and the preparation and organization of my data are reflected in my work and the good results.
  • Prometheus has been in charge of giving more professional support to our operation and, of course, to the response to all our external commercial relationships.

Cons

Nagios Enterprises

  • 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.

  • As I said earlier I have not encountered any major drawback just minor challenges like new users may find Prometheus a bit overwhelming with its different modules can bring confusion.
  • Also they can face issues with PromQL can be somehow complex while building an advanced dashboard.

    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.

    Usability

    Nagios Enterprises

    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.

    Nagios Enterprises

    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.

    Alternatives Considered

    Nagios Enterprises

    Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

    Highly customized pricing plans to choose from. Lower pricing for the same features compared to competitors. Easy to reach the support team, which provided detailed documentation and helped set up the Prometheus. Monitoring metrics gets very easy after the integration with Grafana. It also has a sophisticated alert setting mechanism to ensure we don't miss anything critical.

    Return on Investment

    Nagios Enterprises

    • With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
    • You can set up as many alerts as you want without incurring any fees.

    • The investment was already recovered commercially speaking in 4 months.
    • We have had good acceptance and the lost times have decreased daily.
    • It has facilitated the movement of appointments, especially to marketing outside the department, due to the possibility of those in charge of monitoring the PCs in real-time outside the office.
