Excellent tool that's widely used - and best of all, it's free!
Nagios is an excellent open-source tool. There is a large community of users who have developed scripts and make them available for other users for just about anything you could ever want to monitor. Nagios is being used to monitor various applications, servers, websites, and services. Once you have set up a few things it is very straight forward to use and configure templates to repeat the task for new devices.
Nagios is used to monitor and report on the utilization of our network and server hardware. It's primarily used for our IT department and DevOps team. We use it to monitor switch and server status, and in combination with PTRG Nagios, it gives us great reporting and details within our network infrastructure.

Simple to use - good value for your money
Device availability (Uptime/Downtime) both real time and overtime, SNMP monitoring (CPU utilization, memory, temperature, fan status, disk capacity, etc.), latency tests.
We use Nagios to monitor our internal IT infrastructure in our headquarters and remote office. Nagios being open source has great benefits by providing vast amounts of configurations capabilities and the support community is another added bonus. We have been pro-active and less reactive when issues arise and reliability has greatly increased.

Nagios quick review
In my case, Nagios is used as early alert on sensitive equipment in our data center such as servers, switches, routers and firewall, even on precision air conditioner, all of them using SNMP protocol.
Is used by the Data Center Operations Center Department and I think is not a business problem that it addresses but a matter of efficiency in the use of technical resources.

Powerful Monitoring tool
We use Nagios along with several hundred custom checks to monitor our environment and customer environments. We have been running Nagios Open source for 15 years, I have been directly involved in managing it for 5 years. It addresses our need for Systems monitoring and works alongside many other tools in our Open source Ecosystem
As an alternative to a paid solution, Nagios Core was implemented as a monitoring tool for several servers. The solution if successful would have been rolled out to all servers in the organization providing a solid monitoring appliance at no cost.

Nagios - Open Source Network Monitoring
Nagios is being used to monitor and report on the utilization of some of our network hardware. It's primary use is restricted to our IT department, with a couple of additional users. We use it to monitor switch status, and mated with MRTG Nagios gives us bandwidth detail on a per port basis.

Nagios: DIY Full Stack Monitoring
We use Nagios to monitor our servers to make sure they are online and healthy. We use it in addition to third-party monitoring services so we have redundancy in monitoring. Nagios tells us if the host is up or not and if any of its services are struggling. The ability to monitor services is nice because it gives us an early warning and we can fix problems before they become critical. We are using Nagios to monitor basic services like web servers and databases.
We use Nagios to monitor applications and computing resource conditions, alerting us when there are any unusual events. We also use it for generating data and network maps that we monitor.

The Best Infrastructure Monitoring Tool
Score 9 out of 10
Vetted Review
Verified User
We use Nagios to monitor our servers, printers, and network devices. It is an excellent tool for getting a quick eye on your network and deciding if anything needs action preemptively. It has alerts you can configure that also keeps you immediately aware of items that need action NOW. I use this software every day and many times throughout the day.

Nagios Empowered Monitoring
As Nagios was the first monitoring system available for users about 15 years ago, I decided to implement the monitoring solution for a few dozen servers in the organization. However over time, the server-count had increased to 500+ while service-counts increased to 5000+. Nagios continued to remain stable for years on a simple dual-core(2Gb machine). Its ability to proactively detect issues in the system keeps our engineers informed hours (or days) ahead of a pending disaster.
As Nagios employes both Pull & Push Monitoring, implementing the plugins behind a firewall was never a hassle. Customizations were simple as any engineer with basic computer language knowledge can create plugins within minutes. I specifically choose bash, java & php as that's more familiar to me, while others chose Python,Perl or C#.
I have configured Nagios with the following technologies for better user experience.
- MySQL (Storage & Retrieval) using the NDOUtil
- NRDP (For push alerting when your servers are not accessible due to firewall rules)
- Pnp4Nagios (for basic RRD graphing - I have tweaked the RRD settings to allow granular data over months of storage)
- Grafana (for easy aggregated graphing, dashboards, heat-maps, alerts, user )

Nagios Overview
I recommend Nagios for whole servers, routers, switches on organizations, and application too. Nagios will send emails. Nagios will show information on equipment or applications with trouble. Nagios is very powerful.

Great for smaller and medium orgs. If larger, configure it right. Don't over-customize.
Nagios agent comes standard on our servers for our enterprise. It's used for component monitoring out of the box and can have other checks added for custom apps, calls, etc. Every department's server has Nagios running in one form or another.

Three Cheers for Nagios!!!
Nagios is being used primarily by the IT department but the management team makes use of its reporting features.
