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.

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"Dashboard provides monitor of total assets."

"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."

"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."

More Nagios Core pros

"Versa Director's best feature is the ease of configuration and customer and vendor management."

"The most valuable feature of Versa Director is analytics."

Cons

"The scalability needs improvement, it's not scalable at this time."

"The user interface could be more interactive because it is pretty basic."

"The initial setup process could be easier."

"Nagios Core can improve the graphical interface, it would make things a little easier."

More Nagios Core cons

"Versa Director's deployment process is not the best."

Pricing and Cost Advice

"It's free."

"Nagios Core is an open source solution, and there are no licensing fees."

"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."
