Discovery is used to identify if there are any new machines available that can be added to VCM for management. If we don't do it, then we need to manually add and license the machines to be managed.
VCM must discover machines in your environment before you can collect data from them. You can create a discovery rule to discover all machines or you can apply a filter to limit the machines that VCM discovers.
Note
Note that the vCenter discovery must occur after the vCenter Collection. This is counter-intuitive, but simply put, the vCenter discovery is finding new VMs that have come under the vCenter management through the vCenter collection.
Note that for servers and workstations, exceeding the limit on your license key produces warnings but does not restrict the VCM operation.
In this recipe, we are scheduling a vCenter discovery so that all the newly created VMs can be added, and agent can be installed and licensed in VCM.
