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. 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 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."
"The Centerity gives us exactly what we need from performance system monitoring."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"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."
"The solution is quite efficient."
"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."
"Provides timely notifications."
"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."
"I like the way the solution sends alerts and how it keeps on escalating them."
 

Cons

"The GUI must be improved. Graphs must be changed including high level maps"
"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 tool needs to improve the integrations."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"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."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"We're using the free version, which limits us in terms of the things that we can do."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

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.
What is your primary use case for Nagios Core?
I was a senior system administrator. I've been using Nagios Core for more than ten years now. It can be used to monitor hosts, such as machines, and monitor services of any kind. I'm using it to mo...
