Features: Centerity Monitor provides real-time performance analytics, automated incident response, and comprehensive monitoring solutions. Nagios Core offers flexibility, a wide range of plugins, and customizable monitoring setups.

Room for Improvement: Centerity Monitor could enhance compatibility with third-party tools, offer broader customization options, and improve the granularity of monitoring metrics.

Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

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."

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

"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."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"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."

"The reporting structure and the feature set are valuable to me."

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

"We use the product to monitor server applications."

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

Cons

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

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"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."

"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."

"The scalability needs improvement, it's not scalable at this time."

"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."

"There is room for improvement in the graphics."

"The UI is a little outdated and graphics could be displayed in a better way."
