So the Nagios [Core] gave us valuable features like report analysis and graphical structure, so it will easily evaluate and track the issue. Also, the email function is very useful, so we get informed at very crucial times with findings, and also generate templates for popular endpoints which make it very better.

For us, we use it just [as] a backup for our main Network Monitoring Systems since it only uses ICMP to monitor the device. If you are looking [for] in monitoring devices using SNMP that will provide you auto discovery and details of your device, Nagios is not for you. But as a backup platform, it is a great tool.

If you have an organization with more than 10 critical business systems, then Nagios Core is a great, free solution for monitoring. If you're looking to monitor a network or network performance, then Nagios Core is not the best choice; there are other solutions that handle that better. Nagios Core is really good at monitoring hosts and components on a host, such as a MySQL database.

Excellent for host-level integration and usability. End users can get right in and use the tool to monitor their environment. Easily able to add tags and groupings, which is a must nowadays. The tool can integrate with LDAP and active directory, but we don't use that. We do everything on-premises and keep users separate.

Nagios does standard monitoring of servers and network devices very well. If you have an environment with many basic protocols to monitor, Nagios will work well out of the box for you. It also runs very reliably. Once it is set up, I have not had many problems with the service being available.

Nagios Core is a great tool. It's open-source and free, there is a great community, shared plugins, and many other reasons which make it a great tool. It's very good for small to medium-sized businesses and if you configure it appropriately it could be used for larger organizations as well.

Nagios is great to give you a top-down view of your entire IT infrastructure. It's another tool to improve reliability and be more pro-active than reactive to problems within your IT infrastructure. I would recommend Nagios in all environments from small businesses to enterprise environments.

Nagios is well suited to monitoring devices such as network switches, printers, and especially servers, as well as if administrators or end users wish to receive alerts for downtime or other outages so they can be addressed. It is less appropriate for if auditing of services or logging of those services is desired, or if anything beyond up/down or specific application checks are needed in order to monitor a service.

Nagios is great at monitoring your internal IT infrastructure and is highly customized to fit your exact needs. Our reliability has improved vastly. We are able to monitor the system more closely and resolve issues before they happen. It's less suited for a hybrid infrastructure.

In Data Centers Controls as first alert dashboards, in a Network Operation Center to map hot spots or graphs data bandwidth usage. Take advantage of event handlers to perform automated event based tasks or trigger email (sms) alert as a result of those events. As a result of his difficult configuration process it may not suitable for escenarios where you have to scale as a regular basis.

It is well suited for use with skilled system administrators who know what they need to monitor and what they need for alerts.
It is not well suited if you just want general monitoring with out a good grasp of why they are monitoring.

Nagios Core would best be suited for a small organization with about 50-100 computers. With the free version, the ability to deploy on a Linux box allows the business to benefit from a free, fully functional and heavily customization tool that can, if done right, hold its own against paid options.

Nagios is primarily an open source technology. It's very well suited for environments that either work on a restricted budget and require a solution that can be customized heavily to fit. I would not recommend it to anyone with a limited time frame, tech skills, or someone looking for a canned monitoring or data collecting solution.

Nagios is great for engineers, sys admins, and do it yourself types. If any of my colleagues are of this type of field I'll recommend Nagios. If you are not familiar with the Linux command line, I would sway you away from Nagios and recommend a third party web-based monitoring service instead.

Nagios is essential in a scenario where it is necessary to solve problems with monitored computational resources as soon as they are detected. It's also suited to manage SLA of network links and monitor to generate data about the use of these computational resources. I do not see an environment where it would not be appropriate to use the tool.

Nagios is well suited for everyone whether there is 1 server or 100+. It's a way of keeping your server secure and up. The alternative is just keeping the terminal open 24/7 but that won't tell you everything at once. You would need to look for different issues which Nagios assists with.

I don't know if there is a less appropriate scenario. If you have an infrastructure and need to monitor it, Nagios is the best option. Not only can you monitor, but Nagios also alerts users and allows you to take actions depending on the alert. It helps a lot with automatization and is a tool you must have in your infrastructure.

If you have a lot of servers and network devices to keep an eye on Nagios is an excellent product. It gives you both a quick overview of the network as well as alerts you when action is needed. As long as you are comfortable with Linux I highly recommend you implement Nagios as your infrastructure monitoring tool.

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.

  • The best scenarios: Big or medium companies with own [their] datacenters. For example 20 or more servers, routers, switches.
  • The worst scenarios: Servers in the cloud (they can use other solutions) or less than 5 servers in the company.

Great for basic, up/down component monitoring. Also good for canary checks, file directory monitoring, etc. It's a good Boolean monitoring tool, but once it fires off an alert, obtaining more data is problematic. It's nice, but it can be noisy if not implemented in an enterprise-wide, scalable, and manageable way.

This tool is very appropriate for IT staff to have the information they need at their fingertips. Notifications are timely and response time to issues has been cut down immensely. If you are looking for Nagios to be the one network monitoring tool for your department then you are in the right place. Nagios will allow your staff to focus on problem resolution and create efficiency by putting more information at their disposal.
