The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The reporting structure and the feature set are valuable to me."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"Extensibility is good as this makes it easy to write checks on your own."
"The good thing about Nagios Core is it covers everything."
"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"Nagios Core is very configurable. Whatever you want, you can do it."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"Network quality monitoring of multicast TV channels and other network monitorings."
"The live packet capture feature enables quicker troubleshooting and better network monitoring."
 

Cons

"The UI is a little outdated and graphics could be displayed in a better way."
"Default interface is clunky and slow."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"The scalability needs improvement, it's not scalable at this time."
"t was a little hard to get our setup represented in the configuration."
"The interface could be improved."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"The web interface is ok, but I would like to see if it was possible to group jobs better and to create our own dashboards."
 

Pricing and Cost Advice

"The product is cheaply priced."
"The enterprise version has technical support. The version we are using is free."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is an open source solution, and there are no licensing fees."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"Nagios Core is a cheap solution."
"We are using the open-source, unpaid version."
"Nagios Core is free to use."
