Featured Reviews

Emanuel Kjellin - PeerSpot reviewer
An affordable solution to block and analyze the situation with VPN troubleshooting feature
If Azure Network Monitor is part of the solution, it's a comprehensive tool. For example, during cloud migration, the workload on the cloud can be significant. However, the Ethernet solution is low cost and provides a fast return on investment. In larger scenarios, such as a major deployment, the return on investment might take three months to a year. The solution involves managing workloads, machine storage, and network modes.
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.

Cons
