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

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

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."

"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 user interface could be more interactive because it is pretty basic."

"The interface 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."

"There is room for improvement in the graphics."

"I would like to see more training videos."

"The initial setup process could be easier."

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

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."

"Nagios Core is free to use."

"I would rate the solution's pricing an eight out of ten."

"The product is cheaply priced."

"Lessening the price point would be an improvement."

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

"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."

"Most the plugin features are free."

"Nagios Core is a cheap solution."
