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.

Provides a stable solution but would improve by developing an all-in-one-solution

The advice I would give to anyone looking at implementing Netreo into their organization would be to do your market research and evaluate the product, do not just choose it because someone recommends it to you. Overall, from my perspective, I would rate the solution a seven out of ten.
