Monitoring solution provides comprehensive visibility across IT infrastructure
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.

Quotes from Members

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

Pros

"The Centerity gives us exactly what we need from performance system monitoring."
"The machine learning feature is valuable."
"Centerity is much more than a monitoring tool — it’s a unified, end-to-end, enterprise-class and multi-tenanted AIOps Platform that is purpose-built to help MSPs and data-centers deliver the highest levels of up-time and performance."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"The solution is very complete and mostly easy to manage."
"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"Extensibility is good as this makes it easy to write checks on your own."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
 

Cons

"One of the major improvements should be it implementation as a SaaS"
"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"The GUI must be improved. Graphs must be changed including high level maps"
"They should simplify the features so it becomes easier to setup out of the box."
"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 scalability needs improvement, it's not scalable at this time."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"There is room for improvement in the graphics."
"I would like to see more training videos."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"I like to have the option to configure Nagios using the web interface."

What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
What needs improvement with Nagios Core?
The dashboard should be improved. It's very simple. I don't have a very clear or specific suggestion. You can change the skin of the dashboard, however, it's good for me.
