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."

"Key features include the GUI interface, its notification capabilities, and the real-time reporting."

"The good thing about Nagios Core is it covers everything."

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

"I like the way the solution sends alerts and how it keeps on escalating them."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"Nagios Core is stable."

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

More Nagios Core pros

Cons

"They can improve the functionality that provides some numbers related to the behavior of the metrics."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"There is room for improvement in the graphics."

"The initial setup process could be easier."

"I would like to see more training videos."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

"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."

"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."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

Overview

Centerity is the pioneer provider of an All-in-One, IT Monitoring and Business Service Management (BSM) platform.
