Shows question being asked, breaks it down and it'll just show you who's not answering

I wouldn't want the interface to go towards the web because they did have a version that was inside of the TruView product. It was more web-based and, to me, the web-based applications lose the robustness of the intimacy of a true character interface. I liked that they were on that path and I hope that they stay on that path because it just looks like it's a better product. I would like to see a multi-user version where you can have a launch platform and, potentially, instead of buying six licenses you buy 12 seats or something like that. From a centralized platform, you could have multiple users using that particular product in a series of different ways. That's what I'd like to see, rather than having everybody running a standalone one on their own workstation.

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

"What ClearSight will do is it actually maps out the conversation for you."

"It is fairly easy to set up, and we can monitor pretty much everything we want to."

"The application performance monitoring feature is valuable."

"The most valuable features are the reports and the way it generates the report in a graphical manner."

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

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"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."

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

Cons

"I would like to see a multi-user version where you can have a launch platform and, potentially, instead of buying six licenses you buy 12 seats or something like that."

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

"The UI is a little outdated and graphics could be displayed in a better way."

"The alerting mechanism in Nagios Core could be improved."

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

"The initial setup process could be easier."

"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."

"The core version is no match for the XI version."

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

More Nagios Core cons

Pricing and Cost Advice

"It was pretty modest because you could get it in different ways. I think the six licenses, at that time, were about $1,000 each. But then again, I work for a school and educators tend to get discounts on things. So maybe it cost us about five or six hundred a copy."

"We are using the open-source, unpaid version."

"The solution is expensive."

"The enterprise version has technical support. The version we are using is free."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"Nagios Core is a cheap solution."

"Nagios Core is free to use."

"Lessening the price point would be an improvement."

"We are using the free version."
