Provided are techniques for collecting capacity data of virtual machines by leveraging agent data. A list of one or more virtual machines for which capacity data is to be retrieved is obtain from an asset server, where the one or more virtual machines are identified using a licensing measurement. Infrastructure data and hypervisor data are obtained from an infrastructure server. For each of the one or more virtual machines, the infrastructure data and the hypervisor data are used to request, from a capacity scanner on each of the one or more virtual machines, capacity data for that virtual machine. The capacity data for each of the one or more virtual machines is sent to the asset server, and the asset server performs load balancing of software that is to be executed on the one or more virtual machines using the capacity data.
