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."
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"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."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"The solution is very complete and mostly easy to manage."
"I would rate the overall solution ten points out of ten."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
 

Cons

"The GUI must be improved. Graphs must be changed including high level maps"
"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"One of the major improvements should be it implementation as a SaaS"
"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."
"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 initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"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."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"I would like to see more training videos."

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.

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...
