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

"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."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"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."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"Nagios Core is very configurable. Whatever you want, you can do it."
"Dashboard provides monitor of total assets."
More Nagios Core pros
"The solution enables dynamic discovery and incorporates a powerful configuration management database, CMDB, along with a strong correlation engine."
"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."
"When it comes to customization, Micro Focus is more mature than its competitors."
 

Cons

"The user interface could be more interactive because it is pretty basic."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"The alerting mechanism in Nagios Core could be improved."
"Nagios Core does not have a graphic display."
"The mapping is a little hard."
"The tool needs to improve the integrations."
"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."
More Nagios Core cons
"The user interface is outdated and needs improvement, especially for service and topology maps."
"It may need a more customizable UI."
"The user interface is outdated and needs improvement, especially for service and topology maps."
"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."
 

Pricing and Cost Advice

"Nagios Core is free to use."
"We are using the open-source, unpaid version."
"It's free."
"We are using the free version."
"The solution is expensive."
"It's free."
"Nagios Core is a cheap solution."
"I would rate the solution's pricing an eight out of ten."
More Nagios Core pricing and cost advice
"Micro Focus' price is on the higher side, but there are other products like CA products and IBM that are more expensive. At the same time, you have to compare the maturity level of the solutions."
