    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.

    If there are a number of different protocols and devices to monitor PRTG is really an all in one solution. There are network specific solutions, telephony solutions, server solutions, etc - but this tool can do anything. Even if you don't use this tool as your main "monitoring solutions" every IT professional should have access to this tool for at least troubleshooting purposes. If you are looking for something specific built for a task you may be able to find [a] more direct and easy tool to use that would be easier and quicker to setup as customization is not needed.

    Pros

    Nagios Enterprises

    • 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.

    • Very, very configurable. You can create all kinds of monitors for all kinds of things. Plus it has loads of suggestions out of the box. It can get complicated but monitoring is complicated. Pretty decent interface and good support - active community.
    • I really liked how easy it was to add alerts by SMS. So easy to setup.
    • I like their sizing models (for purchase). We're actually small enough that we are free. But it's not free as in stripped down - it's free because we don't use many "sensors" and don't honestly have the need.

    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.

    • The probe service can be quite resource-intensive. This can cause false-positive readings from some sensors sometimes.
    • The software gets updated very regularly. Whilst this is usually a good thing to fix bugs etc, it does meantime downtime of the monitoring quite often while they are installed.
    • The ability to create Maps from Libraries. Very specific issue but a lot of people have been asking for it for years and it is still not available.

    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.

    The tool is very intuitive to use and it is Windows-based (everybody knows how to use Windows) so it's easy to get into. Every time is setup in a hierarchy so if you have a good initial hierarchy design, it will really reduce administrative effort down the road.

    Support Rating

    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.

    I am giving this a 6 simply because I have never had to contact support. The online documentation is adequate for most things, and the user-maintained knowledgebase is excellent. The few times I have run into issues that were not easily resolvable with intuitive UI, I was able to find the answers that I needed either in the PRTG-provided documentation, the knowledgebase, or with a quick online web search.

    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].

    I have deployed and tested three products for evaluation I found [PRTG Network Monitor] very easy to deploy, the deployment literally took not more than one hour including basic configuration and network discovery. After deployment few configuration changes and creation of maps, reports and little tweaking is required. [Then] it would go through its process of recommendation that took some time to complete, while [on] other hand other software's took lot of time to install and configure. And features were also missing, which resulted in decision in favor of [PRTG Network Monitor].

    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 ability to analyze multiple pieces of information in one place, especially with historical data, has saved our IT department time and headaches. It would be so much more difficult to trace an issue without PRTG, just relying on event logs and an open task manager window.
    • The cost is not cheap, so it's an expense that hits the bottom line like everything else. Figure in hardware costs as well, ideally a server outside of your main environment.
    • I keep saying this, but the historical data piece is worth so much. There's really no good way to collect all of that information in one place without something like PRTG. And that definitely saves time and money in the long run.
