Featured Reviews

Ayobanji Iluyomade - PeerSpot reviewer
The solution is stable and can be used for monitoring and managing events, but it does not provide application or service monitoring features
We are moving from basic monitoring to AIOps, where we can do things like self-healing. We also want to create dashboards for IT and business users to show the status of their services. We have done a couple of demos. I recommend the solution to others. Overall, I rate the product a seven out of ten.
Nishith-Vyas - PeerSpot reviewer
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.
