What do the VMware tools components ServiceDiscovery and DeviceHelper do?
I realize Specify VMware Tools Components in Silent Installation says ServiceDiscovery "enables the discovery of various services running inside a virtual machine" and DeviceHelper "helps to perform a device check and swap in your virtual machine", but what does that mean? Is ServiceDiscovery only used by vRealize Operations, and I don't need it if I don't have vRealize Operations? Is DeviceHelper similar? Do I need either of these if I am only running ESXi, vCenter Enterprise, and vSan?
