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.
Jeff Cronstrom - PeerSpot reviewer
A highly stable solution that can be used to monitor system availability
The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup. You can clone that service, and it allows you to add new services quickly. You can bring up new servers, and you can easily add them. Also, there's an API to be able to add services as well. We don't use the API. We mostly use the cloning function because it stores everything in a back-end database. The underlying monitoring platform for our version is Nagios. That's where we upgraded from Nagios to Opsview.
