Considered Multiple Products
Nagios Core
Chose Nagios Core
We have tested several other monitoring products which were able to monitor the basic matrix (Memory, DiskUsage, CPU%, UpTime, Running Service Status, Port 80 Up/Down). Although some offered far better UIs, they lacked the ability to monitor ANYTHING. Zabbix, being the only …
Chose Nagios Core
We chose Nagios Core over Zabbix and Zenoss because it was easier to get up and running and configure than the other two products. They required network scanning for assets and then required you to enter every little detail about the host. With Nagios Core, we just entered our …
Chose Nagios Core
Unlike SL1 and IBM NOI, you do not need to buy licenses or pay for support. You can begin deployment immediately. You don't need to purchase expensive equipment or study confusing manufacturer's manuals. Zabbix can also be used freely, but it is not so common and you may need …
Chose Nagios Core
Nagios Core can do literally anything you need it to thanks to the amazing developer community and their ability to program custom addons. Need to monitor servers all over the world.The main advantage of Nagios Core is that it allows you to be aware of the status of each host …
Chose Nagios Core
Other products were evaluated, but Nagios Core was chosen mainly due: 1. To Cost - it is free 2. Exceptional Customization features
Chose Nagios Core
We selected Nagios because of the size of its community. We've used some of the others in the field over the past few years, Nagios had the best features out of the box coupled with it's following made it an easy selection.
Chose Nagios Core
Nagios presents greater robustness, efficiency, and clarity in presenting required results.
Chose Nagios Core
Nagios and these other applications stack up well, but configuring nagios is still by hand for the most part.
Chose Nagios Core
Nagios was the best in the past and why I chose it for many of the companies I've worked for. Also, coming in to a company, there is almost always a Nagios server installed and since everyone knows the software it's easy to write plugins for it. But, in 2015, Nagios is a …
Prometheus
Chose Prometheus
If you combine Prometheus with Grafana, what you get is just amazing. it is basically the best ecosystem that I have seen. Grafana just makes those fancy "iron man" kind of dashboards and it just looks so appealing to your eyes. I have implemented Nagios Core earlier for …
Chose Prometheus
The installation of Nagios Core is quite difficult and the whole system seems us like a huge headache for us the entire team is not much happy with Nagios Core so we take the decision and switch to Prometheus and were really happy with our decision and satisfied.
Zabbix
Chose Zabbix
Well, I am not a decision-maker here, but I believe Zabbix has been adopted as a default choice to be integrated with Nokia OpenStack because of its simplicity of usage & other products were not matured at that time. Single GUI can be used for infrastructure as well as workload …
Chose Zabbix
Zabbix was adopted in our framework due to the value, the hardware requirements, the knowledge we had available and the vast documentation on the internet.
Chose Zabbix
Although we still use Cisco Prime for network devices, when comparing Zabbix with Nagios, for example, you see that Zabbix is more robust, stable, easy to deploy and has an enterprise focus that other tools don't have. Also, the fact that the Zabbix community is very active is …
Chose Zabbix
Zabbix was much better at handling traditional systems, and in ease of customization, both in the system itself, and customizing data sources, such as adding deep MySQL or JMX integrations. It's very good for organizing large-scale (hundreds or thousands of servers) systems; …
Chose Zabbix
I personally prefer Zabbix over any other monitoring software that I have ever tried. Zabbix is so customizable that if there is a feature I need, I can easily implement it. I can then add that feature to a template in no time and have it applied to hundreds, or even thousands, …
Chose Zabbix
More extensive and customizable than SaaS solutions. Much less learning curve than Nagios. Cost is very much lower than SaaS monitoring especially at scales over 1000 hosts ($15,000/month for SaaS!!) Templating systems allows for easy management and monitoring of groups of …
Chose Zabbix
Zabbix had the best support for the devices I initially had in my network, its ability to adapt and change has made it my Swiss Army knife of monitoring tools. While it could benefit greatly from a moderated zabbix community, its support from the open source community has …
Chose Zabbix
Nagios has some advantages over Zabbix like "flapping" detection and multiple alert levels - Error, Warning and OK.
However, the disadvantages of Nagios like needing an addon (NRPE) to monitor remote system internals (open files, running processes, memory, etc), no charting of …
Chose Zabbix
Nagios will always be at or near the top, but I really like how sleek Zabbix is. Also, once it's up and running its really helps keep things in order for you and your customers. As for PandoraFMS, it would have beat out Zabbix, but the documentation on PandoraFMS is really …

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.

This program works from the roots of the problem and creates a professional matrix for each of its users. This will give them more skills and resources to carry out tasks and reduce the difficulties of operating each of the processes of my work, as well as being An ally for the manipulation and operability of all your master data; Prometheus is very easy to recommend since it is a program that fulfills its mission.

Zabbix
Zabbix is very well suited for infrastructure monitoring i.e. the underlying host servers, basically, compute nodes. However, it has limited FM & PM capabilities for the workloads, i.e., the virtual machines (VMs). Zabbix has an easy-to-use GUI which can be explored easily & provides good filtering of the data.

Zabbix
  • Collecting hardware data - CPU, Memory, Network, and Disk Metrics are collected and reported on.
  • Flexible design - It is very easy to build out even very large environments via the templating system. You can also start where you are - network monitoring, server monitoring, etc. and then build it out from there as time and resources permit.
  • Provides a "plugin architecture" (via XML templates) to allow end users to extend it to monitor all kinds of equipment, software, or other metrics that are not already added into the software already.
  • Very complete documentation. Almost every aspect of Zabbix has been documented and reported on.
  • Cost - Zabbix is FOSS software and always free. Support is reasonably priced and readily available.

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.

Zabbix
  • In a busy Zabbix environment, it can easily overwhelm the underlying database. Plan on having SSDs and a significant server infrastructure to keep up with more than a hundred hosts.
  • Building out Zabbix metrics that suit your environment can be very time consuming. When choosing a monitoring platform like Zabbix, expect a steep learning curve and to invest significant resources to make the tool valuable.
  • This is less important than it has been in the past, but current versions of Zabbix still do not handle IPMI checks of hardware very well. We needed to write our own wrapper for IPMI checks rather than using the built in IPMI poller.

Zabbix
It is free. It didn't cost anything to implement (other than my time and the cost incurred for it) and it is filling a badly needed gap in our IT infrastructure. Support is available if we have issues and can be done annually or paid for on a per incident basis as needed. Expansion, updates, and all other future lifecycle activities are likewise free of cost, so as long as someone is able to implement/maintain the software (and the OSS project is maintained) then I imagine the company will never leave it.

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.

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 setup is the most time-consuming portion of using zabbix. It takes a lot of effort to shape it into a usable format and even then it can get very messy. It's not exactly intuitive and as mentioned the UI seems a bit antiquated. If I was to roll out a monitoring solution from scratch, I'd probably look for alternatives which are easier to use and maintain.

Zabbix
We are a mainly Windows environment, so it would be useful if we could have used Active Directory to deploy agents. As of version 4.2, Zabbix has announced a new agent MSI file to allow exactly that. Unfortunately, we didn't have that option. Also, for Linux and MAC deployments, there is no simple way to deploy that. Using remote scripts you may be able to create something, but most places will opt for either SNMP (agentless) or manual installation of agents to add to Zabbix. A way of deploying agents via discovery would go a long way to helping in the adoption of the tool.

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.

Zabbix
We're using the Solarwinds suite as our global monitoring standard, but it is very complex and its licensing model makes it difficult to monitor a wide range of technologies. So, we're using Zabbix as a complement on our monitoring process. Zabbix is a way more flexible and has free integrations to a wide range of technologies. It is also more 'user friendly' and easy to manage.

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.

  • We are still working on the ROI
  • The ROI mentioned during the purchase has not been achieved, however this could be due to lack of data from our side. 2 years of implementation is too early to calculate and confirm the ROI.

Zabbix
  • Zabbix simply makes it easier to identify, and subsequently resolve problems quickly
  • Zabbix gives one web page to look at to see a list of all on-going issue in a single place
  • Zabbix can automate response to alerts. For example, Zabbix allows you the customization to take a monitored server out of production rotation if it is identified as unhealthy
