Great for identifying application interdependencies with helpful support but needs better visualizations

We're just trying to identify the application interdependencies, which normally reside on different servers, including web servers, database servers, enterprise service bus, et cetera, up to your presentation layer before we start moving stuff around. Normally, the reason why we use these tools is to understand what assets we have, where they're deployed, and how they enter and operate before we decide to go move something from point A to point B. The solution is going to allow me to establish a wave or migration plan where you have different waves of migration and then you actually have move groups to try and get your application moved from A to B seamlessly. A to B could be on-premise to on-premise. It could be on-premise to cloud. Et cetera. The solution can tell me what components can I deploy, for example, into a cloud space, without having to refactor my applications since that can be quite time-consuming and costly.

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

"Wire data analytics."

"There are many valuable features in this product, but probably the biggest is the customization capability it has."

"The most valuable features are security detections, perimeter detection, dashboards, and alerts."

"The most valuable feature is the way it handles data, from Layer 2 up to Layer 7. We can see everything that happens in the network."

"Not only can you look at the protocol import level. It also has a live PCAP analysis."

"This solution is more applications reference architecture focused. Its benefit is that it specializes in that space."

"Provides timely notifications."

"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."

"Nagios Core is very configurable. Whatever you want, you can do it."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"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."

"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 most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."

Cons

"We'd like to see a local presence within the region in order to have seamless service whether it's the support, the implementation, or professional services."

"This solution would be improved if it had the ability to retain data longer."

"They have a new solution, ExtraHop Reveal(x), and I think it needs improvement."

"Network visibility is something that needs to be improved."

"They either have to go broad or decide what their bread and butter is and get really good at that."

"I would improve the Rule-Based Access Control (RBAC) by providing granular access control to the data."

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

"Nagios Core does not have a graphic display."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"The dashboard and monitoring features could be improved."

"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."

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

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

"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."

Pricing and Cost Advice

"The pricing is fair considering the value provided."

"The price of this solution for our environment is about £650,000 ($855,000 USD) for three years."

"The pricing is higher than other solutions, but with such good features, I think it's worth it."

"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."

"We are using the free version."

"Nagios Core is free to use."

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

"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."

"It's free."

"The product is cheaply priced."
