Abstract

The present invention allows CPU utilization for a virtual machine (VM) to be captured from a perspective of a host. Specifically, under the present invention, a work request having a set (e.g., one or more) of jobs is received by a host and allocated to a virtual machine on a node. The work request is typically accompanied by an account identifier such as a multi-value billing code. Once the work request is allocated to a particular VM on the node, a “startacct” script is issued, and a first account record is created. Thereafter, the work request is processed and the CPU utilization needed to complete the set of jobs is monitored. Once the set ofjobs is completed, an “endacct” script is issued and a second account record is created. Among other things, the second account record includes the monitored CPU utilization and the account identifier.

Claims

1. A method for capturing Central Processing Unit (CPU) utilization for a virtual machine, comprising:

receiving a work request having a set of jobs in the virtual machine from a host, wherein the work request is accompanied by an account identifier;

creating a first account record for the work request;

processing the work request in the virtual machine to complete the set of jobs; and

creating a second account record for the work request in response to completion of the set of jobs, wherein the second account record indicates the CPU utilization for the virtual machine to process the work request.

2. The method of claim 1, further comprising:

issuing a first script with the account identifier prior to creating the first account record; and

issuing a second script without data after the processing step.

3. The method of claim 1, wherein an account identification within the first account record is set to a default value, and wherein an account identification within the second account record is set to the account identifier.

4. The method of claim 1, wherein the first account record and the second account record each comprise a user identification, an account identification, a date/time stamp, a CPU utilization, and a record type.

5. The method of claim 4, wherein the record type within the first account record is distinct from the record type within the second account record.

6. The method of claim 4, wherein the user identification identifies a name of the virtual machine.

7. The method of claim 1, wherein the CPU utilization is captured in real-time in the second account record.

8. A method for capturing Central Processing Unit (CPU) utilization for a virtual machine, comprising:

issuing a first script in response to a work request having a set of jobs received by the virtual machine from a host;

creating a first account record for the work request in response to the first script;

issuing a second script in response to completion of the set of jobs in the virtual machine; and

creating a second account record for the work request in response to the second script, wherein the second account record indicates the CPU utilization for the virtual machine to complete the set of jobs.

9. A system for capturing Central Processing Unit (CPU) utilization for a virtual machine, comprising:

a system for creating a first account record for a work request having a set of jobs received by the virtual machine from a host, wherein the work request is accompanied by an account identifier; and

a system for creating a second account record for the work request in response to completion of the set of jobs by the virtual machine, wherein the second account record indicates the CPU utilization for the virtual machine to complete the set of jobs.

10. The system of claim 9, further comprising:

a system for issuing a first script with the account identifier; and

a system for issuing a second script without data.

11. The system of claim 9, wherein an account identification within the first account record is set to a default value, and wherein an account identification within the second account record is set to the account identifier.

12. The system of claim 9, wherein the first account record and the second account record each comprise a user identification, an account identification, a date/time stamp, a CPU utilization, and a record type.

13. The system of claim 12, wherein the record type within the first account record is distinct from the record type within the second account record.

14. The system of claim 12, wherein the user identification identifies a name of the virtual machine.

15. The system of claim 9, wherein the CPU utilization is captured in real-time in the second account record.

16. The system of claim 9, wherein the account identifier comprises a multi-value billing code.

17. The system of claim 9, further comprising a system for monitoring the CPU utilization of the virtual machine as the set of jobs are completed by the virtual machine.

18. A program product stored on a computer useable medium for capturing Central Processing Unit (CPU) utilization for a virtual machine, the computer useable medium comprising program code for causing a computer system to perform the following steps:

issuing a first script in response to a work request having a set of jobs received by the virtual machine from a host;

creating a first account record for the work request in response to the first script;

issuing a second script in response to completion of the set of jobs in the virtual machine; and

creating a second account record for the work request in response to the second script, wherein the second account record indicates the CPU utilization for the virtual machine to complete the set of jobs.

19. The program product of claim 18, wherein an account identification within the first account record is set to a default value, and wherein an account identification within the second account record is set to an account identifier that accompanies the work request.

20. The program product of claim 18, wherein the first account record and the second account record each comprise a user identification, an account identification, a date/time stamp, a CPU utilization, and a record type.

21. The program product of claim 20, wherein the record type within the first account record is distinct from the record type within the second account record.

22. The program product of claim 20, wherein the user identification identifies a name of the virtual machine.

23. The program product of claim 18, wherein the computer useable medium further comprises program code for performing the following step:

monitoring the CPU utilization of the virtual machine as the set of jobs are completed by the virtual machine.

24. A method for deploying an application for capturing Central Processing Unit (CPU) utilization for a virtual machine, comprising:

providing a computer infrastructure being operable to;

issue a first script in response to a work request having a set of jobs received by the virtual machine from a host;

create a first account record for the work request in response to the first script;

issue a second script in response to completion of the set of jobs in the virtual machine; and

create a second account record for the work request in response to the second script, wherein the second account record indicates the CPU utilization for the virtual machine to complete the set of jobs.
