Senior System Administrator at Interactive Group
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.

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.
