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."
"The Centerity gives us exactly what we need from performance system monitoring."
"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 poller is really good, I can easily implement new stuff and it is scalable."
"Dashboard provides monitor of total assets."
"The solution is very complete and mostly easy to manage."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
 

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"
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"The scalability needs improvement, it's not scalable at this time."
"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 would benefit from aggregations if a particular server goes down."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."

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...
