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

"The most valuable features are security detections, perimeter detection, dashboards, and alerts."
"This solution is more applications reference architecture focused. Its benefit is that it specializes in that space."
"There are many valuable features in this product, but probably the biggest is the customization capability it has."
"Not only can you look at the protocol import level. It also has a live PCAP analysis."
"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."
"Wire data analytics."
"Dashboard provides monitor of total assets."
"The good thing about Nagios Core is it covers everything."
"Provides timely notifications."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"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."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"Nagios Core is stable."
 

Cons

"They either have to go broad or decide what their bread and butter is and get really good at that."
"They have a new solution, ExtraHop Reveal(x), and I think it needs improvement."
"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."
"Network visibility is something that needs to be improved."
"This solution would be improved if it had the ability to retain data longer."
"I would improve the Rule-Based Access Control (RBAC) by providing granular access control to the data."
"The alerting mechanism in Nagios Core could be improved."
"Would benefit from aggregations if a particular server goes down."
"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."
"t was a little hard to get our setup represented in the configuration."
"The mapping is a little hard."
"The tool needs to improve the integrations."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
