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.

Dynamic discovery and effective network topology make IT monitoring valuable
The solution enables dynamic discovery and incorporates a powerful configuration management database, CMDB, along with a strong correlation engine. It covers the entire span of the infrastructure, including servers and network operations. It also adapts well to different environments, showing network topology effectively, making the network monitoring tool quite valuable.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"The most valuable feature is the performance parameters of the system."
"The application performance monitoring feature is valuable."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"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."
"I would rate the overall solution ten points out of ten."
"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."
More Nagios Core pros
"When it comes to customization, Micro Focus is more mature than its competitors."
"We can detect non-compliant devices and automate remediation actions to cover the gap in the configuration standards."
"The solution enables dynamic discovery and incorporates a powerful configuration management database, CMDB, along with a strong correlation engine."
"The solution enables dynamic discovery and incorporates a powerful configuration management database, CMDB, along with a strong correlation engine."
 

Cons

"The scalability needs improvement, it's not scalable at this time."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The UI is a little outdated and graphics could be displayed in a better way."
"The mapping is a little hard."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"The user interface could be more interactive because it is pretty basic."
"Nagios Core does not have a graphic display."
More Nagios Core cons
"Micro Focus Network Management doesn't support end-to-end monitoring of cloud infrastructure. Micro Focus might have different cloud solutions for cloud automation and hybrid cloud management. There are a lot of products that also support automation. That is different, but it should monitor the cloud from an IT operations management perspective."
"It may need a more customizable UI."
"The user interface is outdated and needs improvement, especially for service and topology maps."
"The user interface is outdated and needs improvement, especially for service and topology maps."

More Nagios Core pricing and cost advice
