Additionally, Nagios proves its worth in data centers by issuing early alerts on sensitive equipment such as servers, switches, routers, firewalls, and air conditioners.

Old reliable solution
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 paid support from the manufacturer. Sometimes software manufacturers fail to correct errors in their programs in a timely manner, and you are limited in the ability to adapt them to your own needs
- Prometheus and Grafana
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 and services belonging to a network. - Another advantage that Nagios Core has is that it has several types of alerts, with which it indicates the type of failure that a host can present and thus be able to solve it as quickly as possible

Nagios for the win
As a backup NMS, it is better to invest to Nagios since it costs less than any other competitors which [provide] the same level of service. Maybe PRTG gives more features but you don't need all [those] features for your daily use so Nagios gives you what you need when it comes to monitoring.

Nagios Core--The best free monitoring solution around!
- Zabbix and Zenoss Cloud
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 hosts in a single configuration file, then added services for each one. It took about an hour to begin monitoring 25 hosts.

Nagios Core - sit back and monitor at ease!
Nagios is a great tool for the price. Lots of bang for your buck if you know what I mean. The tool installs easily and has a very lightweight footprint. This also allows for great batch installation and configuration. Tags can be applied and pushed throughout the org. We'll continue to use it.

Industry standard monitoring
Centreon has some added benefits to Nagios, mostly in how configurations are made and data is presented. Nagios is perhaps more reliable because of its simplicity. They are both based off of Nagios, so they are similar in many ways, but Centreon adds some of their own customizations and interface stuff on top.

Excellent tool that's widely used - and best of all, it's free!
- SolarWinds Server & Application Monitor
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.
Nagios is opensource and free compared to any other competitors out there. The support forums are great. You can fully scale Nagios from small to large environments.

Nagios - Open Source Versatile Infrastructure Alerting Solution
Nagios may not have as much metrics reporting or as many visualizations as the other products, but outdoes the others in ease of configuration and the ability to deliver multi-faceted alerting across a variety of applications, with the help of plugins or with the user community's assistance on coding checks. The flexibility of scripts that support its plugins are also superior to the other products.

Simple to use - good value for your money
The cost is considerably better. Others are probably more complete and even overkilled if all you're looking for is simple SNMP alerting and reporting. If you're looking for integrated analytics or more complex reporting/alerting, there might be better options. Nagios also provides basic NetFlow monitoring in a separate module (also purchased separately) but I don't believe it's all that intuitive and might require additional efforts to set it up compared to other NetFlow tools.
PTRG gets expensive after the free 100 endpoints for small organizations.

Powerful Monitoring tool
Commercial tools where expensive and not as capable for our needs.
Many had other functions that where not as useful for monitoring, such as automation, scripting, software installation. Many of which we had migrated to purpose-built tools that served our needs better.

- Zabbix and WhatsUp Gold
Other products were evaluated, but Nagios Core was chosen mainly due:
1. To Cost - it is free
2. Exceptional Customization features
3. Tremendous Community support
4. Ability to run on older hardware

Nagios - Open Source Network Monitoring
- Zabbix and Spiceworks
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.
Nagios presents greater robustness, efficiency, and clarity in presenting required results.

Nagios in the beginning use stages in Higher Education
We have actually tried several. Nagios does what it was designed to do well. Some of the other products we have do more than Nagios, but they were designed to do more detailed and specific things. Many we have found do a good bit less than Nagios does. Nagios is a nice product for doing what it was designed to do.

I have used both Zabbix and Nagios. Nagios is by far easier to use and configure. I like the layout better and love using it every day. It is my product of choice.

Nagios Empowered Monitoring
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 contender worthy of competing, is a good alternative to Nagios. We also tried Zenoss Core & OpenNMS which were good enough for non-Linux engineers to get started with. OP5 was another service-oriented monitoring solution we evaluated. Apart from Nagios, Consul is heavily used to monitor & register the micro-service systems & end-point URLs. Due to the time invested (9+years) in Nagios, we were able to get more components installed/configured easily than alternatives.

Great for smaller and medium orgs. If larger, configure it right. Don't over-customize.
Nagios is a good start, but as soon as an alert is triggered, you have to go searching and digging. It's better as a trigger and integrated with more robust, intelligent monitoring tools.

Three Cheers for Nagios!!!
- SolarWinds Log & Event Manager and Splunk Cloud
Nagios is an easy to use intuative tool that gives a great return on investment. It has better monitoring features that IT needs than competitors and won't break the bank. Support for this tool is first class and the techs will help you to get the most out of the product.
