Collecting capacity data of virtual machines by leveraging agent data

1. A computer-implemented method, comprising operations for:

obtaining, from an asset server, a list of one or more virtual machines for which capacity data is to be retrieved, wherein the one or more virtual machines are identified using a licensing measurement;

obtaining infrastructure data and hypervisor data from an infrastructure server;

for each of the one or more virtual machines, using the infrastructure data and the hypervisor data to obtain, from a capacity scanner on each of the one or more virtual machines, the capacity data for that virtual machine by:

selecting a virtual machine of the one or more virtual machines;

identifying a Unique Universal Identifier (UUID) for the virtual machine in the infrastructure data;

identifying a hypervisor server host for the virtual machine having the UUID;

identifying the hypervisor data for the hypervisor server host; and

using the UUID and the hypervisor data for the hypervisor server host to access the virtual machine and obtain the capacity data from the capacity scanner on the hypervisor server host; and

sending, to the asset server, the capacity data for each of the one or more virtual machines, wherein the asset server performs load balancing of software that is to be executed on the one or more virtual machines using the capacity data.

2. The computer-implemented method of claim 1 , wherein one or more agents of the infrastructure server are deployed on the virtual machines to obtain the infrastructure data.

3. The computer-implemented method of claim 1 , wherein the infrastructure data includes, for each virtual machine of the virtual machines, the UUID of that virtual machine and an indicator of which virtual center server is a location of that virtual machine.

4. The computer-implemented method of claim 3 , wherein the UUID is verified by checking one or more of a plurality of virtual center servers.

5. The computer-implemented method of claim 1 , wherein the licensing measurement is associated with a customer and identifies the one or more virtual machines that are licensed by that customer.

6. The computer-implemented method of claim 5 , wherein the virtual machines are registered on the infrastructure server.

7. A computer program product, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to perform operations for:

obtaining, from an asset server, a list of one or more virtual machines for which capacity data is to be retrieved, wherein the one or more virtual machines are identified using a licensing measurement;

obtaining infrastructure data and hypervisor data from an infrastructure server;

for each of the one or more virtual machines, using the infrastructure data and the hypervisor data to obtain, from a capacity scanner on each of the one or more virtual machines, the capacity data for that virtual machine by:

selecting a virtual machine of the one or more virtual machines;

identifying a Unique Universal Identifier (UUID) for the virtual machine in the infrastructure data;

identifying a hypervisor server host for the virtual machine having the UUID;

identifying the hypervisor data for the hypervisor server host; and

using the UUID and the hypervisor data for the hypervisor server host to access the virtual machine and obtain the capacity data from the capacity scanner on the hypervisor server host; and

sending, to the asset server, the capacity data for each of the one or more virtual machines, wherein the asset server performs load balancing of software that is to be executed on the one or more virtual machines using the capacity data.

8. The computer program product of claim 7 , wherein one or more agents of the infrastructure server are deployed on the virtual machines to obtain the infrastructure data.

9. The computer program product of claim 7 , wherein the infrastructure data includes, for each virtual machine of the virtual machines, the UUID of that virtual machine and an indicator of which virtual center server is a location of that virtual machine.

10. The computer program product of claim 9 , wherein the UUID is verified by checking one or more of a plurality of virtual center servers.

11. The computer program product of claim 7 , wherein the licensing measurement is associated with a customer and identifies the one or more virtual machines that are licensed by that customer.

12. The computer program product of claim 11 , wherein the virtual machines are registered on the infrastructure server.

13. A computer system, comprising:

one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices; and

program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, to perform operations comprising:

obtaining, from an asset server, a list of one or more virtual machines for which capacity data is to be retrieved, wherein the one or more virtual machines are identified using a licensing measurement;

obtaining infrastructure data and hypervisor data from an infrastructure server;

for each of the one or more virtual machines, using the infrastructure data and the hypervisor data to obtain, from a capacity scanner on each of the one or more virtual machines, the capacity data for that virtual machine by:

selecting a virtual machine of the one or more virtual machines;

identifying a Unique Universal Identifier (UUID) for the virtual machine in the infrastructure data;

identifying a hypervisor server host for the virtual machine having the UUID;

identifying the hypervisor data for the hypervisor server host; and

using the UUID and the hypervisor data for the hypervisor server host to access the virtual machine and obtain the capacity data from the capacity scanner on the hypervisor server host; and

sending, to the asset server, the capacity data for each of the one or more virtual machines, wherein the asset server performs load balancing of software that is to be executed on the one or more virtual machines using the capacity data.

14. The computer system of claim 13 , wherein one or more agents of the infrastructure server are deployed on the virtual machines to obtain the infrastructure data.

15. The computer system of claim 13 , wherein the infrastructure data includes, for each virtual machine of the virtual machines, the UUID of that virtual machine and an indicator of which virtual center server is a location of that virtual machine.

16. The computer system of claim 15 , wherein the UUID is verified by checking one or more of a plurality of virtual center servers.

17. The computer system of claim 13 , wherein the licensing measurement is associated with a customer and identifies the one or more virtual machines that are licensed by that customer.

18. The computer system of claim 17 , wherein the virtual machines are registered on the infrastructure server.
