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.

High performance, quick packet monitoring, and helpful support

The solution could improve by having automatic mitigation. For example, as soon as a problem occurs the solution alarms and mitigates the situation immediately. In a feature release of the solution they should add features related to automation and remediation. Automation would help increase level of security the solution provides.
