After trying several network monitoring apps, I am currently using LibreNMS. I just installed Nagios Core (and I am open to upgrading to the CSP for unlimited). Before diving into the CSP unlimited, I want to get feedback to ensure it will do what I need with the least manual configuration possible. I have a small department, three techs, including me. We have 14 interconnected locations via VPN using Sonicwalls, Netgear, Grand Stream switches, and about 500 Windows workstations and servers. As I am trying the Core, I notice all the configurations, including adding devices, are done manually. If I upgrade to CSP, will the configuration be the same, all manual-based via command?
