Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Real-time dashboards have improved our deployment monitoring and incident response
We are using Opsview ourselves, rather than being a consultant or a reseller. We do not use its auto-discovery feature. We do not utilize its API driven architecture. I do not know what metrics we use to assess the effectiveness of Opsview's hybrid IT monitoring. Overall, I am pretty satisfied with Opsview as it is good for what it does. I do not know if Grafana has any other advantages besides better stats, as I am not involved in that side. Based on my experience, I would still recommend Opsview to others as it is good for what it does. I gave this review a rating of 8.
