If I set up NPM 10.3 with the necessary administrative credential to poll a VCenter server, do I even need SNMP enabled on the ESX host servers?
I understand that all data with the exception of CPU and memory is derived from the VMWare API, so what if anything does SNMP give me that VMWare and WMI do not?
And a related question...if I run a Discovery of two VCenter servers, and the results come back with "unknown" IPs that were discovered with ICMP only, what does that mean?
Thank you for any help.
