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

"There are many valuable features in this product, but probably the biggest is the customization capability it has."
"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."
"This solution is more applications reference architecture focused. Its benefit is that it specializes in that space."
"The most valuable features are security detections, perimeter detection, dashboards, and alerts."
"Wire data analytics."
"Not only can you look at the protocol import level. It also has a live PCAP analysis."
"The application performance monitoring feature is valuable."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Nagios Core is stable."
"Nagios Core is very configurable. Whatever you want, you can do it."
"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."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
 

Cons

"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."
"Network visibility is something that needs to be improved."
"This solution would be improved if it had the ability to retain data longer."
"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."
"They have a new solution, ExtraHop Reveal(x), and I think it needs improvement."
"The interface could be improved."
"The dashboard should be improved."
"It is a bit slow due to latency."
"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."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"The scalability needs improvement, it's not scalable at this time."
 

Pricing and Cost Advice

"The pricing is higher than other solutions, but with such good features, I think it's worth it."
"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."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"I would rate the solution's pricing an eight out of ten."
"The enterprise version has technical support. The version we are using is free."
"Nagios Core is a cheap solution."
"We are using the free version of Nagios Core."
"We are using the free version."
"The product is cheaply priced."
"We are using the open-source, unpaid version."

What do you like most about Nagios Core?
What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services.
What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
What needs improvement with Nagios Core?
The dashboard should be improved. It's very simple. I don't have a very clear or specific suggestion. You can change the skin of the dashboard, however, it's good for me.
