I am installing NPM 12.2 that has VMAN 8.0 built-in. Our environment that I want to monitor is all VMWare. It's a mix of Windows, Linux, and virtual network devices. To monitor all these hundreds of devices, do I need to run a discovery in NPM and configure each device to be monitored? Or can I just point to my vCenter and then see all the devices in my Orion web console and still configure alerts for these devices?
