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.

Offers user monitoring and Internet insights and include customer journeys
It’s evolving; I feel it needs more holistic integration. It needs more improvement. It’s very good, but the integration can be slightly complicated on different platforms. I used it for a healthcare organization, and the integration was slightly challenging. In future releases, I would like to explore AI capabilities. AI would be more valuable because it works across different cloud and server systems. It looks into issue detection and insight modeling, so that is something I feel will be very helpful in the near future. More AI because of compliance and other challenges, not because of the product challenge. It’s about regulations, and we have HIPAA laws in the US and many different kinds of laws. Because of that, these specific elements and certain units don’t allow the tooling system to be fully utilized. We also support a certain segment of healthcare, which is the army healthcare segment, which is more government-controlled. There are certain restrictions in moving into the cloud. That’s where I thought those elements might need some more improvement. Also, looking into how we’ll be able to use more data visualization. It has it, but it doesn’t give you everything. If you look into the elements of use and so many other elements are there, but the UI/UX also has to be improved a bit, I feel. From a developer’s standpoint, it’s very easy, but from a consultant’s standpoint, there can be more enhancement, like one-click view and one-click report generation. Those things should be more seamless.

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 feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"The solution is quite efficient."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"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."
"We use the product to monitor server applications."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"The good thing about Nagios Core is it covers everything."
"The most valuable features of ThousandEyes are the full monitoring capabilities and the ability to identify the exact location of problems in the path between the application and the end-user."
"The company provides excellent service."
"The solution's most valuable feature is network security."
"The installation process is not hard at all."
"The most valuable aspect of the solution was the ability to see how the connection quality is between the sites and get an alert if it was turning bad."
"The most valuable feature of ThousandEyes is user-friendliness. It has been essential for us to have a solution that is easy to use."
"One feature I liked is end-user monitoring."
"The most valuable features are integration and ease of use."
 

Cons

"I believe Nagios Core will need to provide an option for big data platforms in the future."
"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."
"The UI is a little outdated and graphics could be displayed in a better way."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"Nagios Core does not have a graphic display."
"The tool needs to improve the integrations."
"Would benefit from aggregations if a particular server goes down."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"More detailed documentation explaining the metrics and the testing mechanisms would be helpful."
"ThousandEyes could improve the dashboards by adding more features."
"The guest portal is hard to use."
"There is room for improvement in terms of customization and user-friendliness."
"It might be practical to extend monitoring capabilities to include network devices"
"Presently, it lacks the ability to integrate with other Cisco products."
"We can show the traffic path in some cases, but it's almost impossible to do so in cloud networks like CDN, Akamai, or Microsoft."
"I would like the product to offer more agility."
 

Pricing and Cost Advice

"Most the plugin features are free."
"We are using the free version."
"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."

"I would rate the solution's pricing an eight out of ten."
"Lessening the price point would be an improvement."
"It's free."
"Nagios Core is a cheap solution."
"The solution's pricing is cheap; I rate it a five out of ten."
"It is a quite expensive solution."
"The solution costs several thousand dollars per year."
