Abstract

An illustrative embodiment disclosed herein is a method by a data analytics chip, including finding a contention within a first predetermined amount of time, sorting user virtual machines based on consumption of each of the user virtual machines, and identifying a first subset of the user virtual machines. The first subset of the plurality of user virtual machines satisfies consumption criteria.

Claims

1. A computer-implemented method comprising:

finding a contention associated with a controller virtual machine within a first predetermined amount of time;

sorting a plurality of user virtual machines coupled to the controller virtual machine, wherein sorting the plurality of user virtual machines is based on consumption of each of the plurality of user virtual machines; and

identifying a first subset of the plurality of user virtual machines, the first subset of the plurality of user virtual machines satisfies consumption criteria.

2. The method of claim 1, further comprising:

delaying a second pre-determined amount of time;

identifying a second subset of the plurality of user virtual machines, the second subset of the plurality of user virtual machines; and

identifying a plurality of bully VMs, the plurality of bully VMs being members of the first subset of the plurality of user virtual machines and the second subset of the plurality of user virtual machines.

3. The method of claim 1, further comprising identifying a plurality of bully VMs, the plurality of bully VMs being member of the first subset of the plurality of user virtual machines.

4. The method of claim 1, wherein the contention is an input output (I/O) contention.

5. The method of claim 1, wherein finding the contention is based on a central processing unit (CPU) usage of the controller virtual machine.

6. The method of claim 1, wherein the consumption criteria comprises an actual size of the first subset of the plurality of user virtual machines being no more than a predetermined size.

8. The method of claim 1, wherein the consumption criteria comprises a first consumption difference between two neighboring user virtual machines in the first subset of the plurality of user virtual machines, the first consumption difference not being more than a first predetermined threshold.

9. The method of claim 1, wherein the consumption criteria comprises a second consumption difference between a last user virtual machine in the first subset of the plurality of user virtual machines and a user first virtual machine outside the first subset of the plurality of user virtual machines, the second consumption difference being at least a second predetermined threshold.

7. (canceled)

10. An apparatus comprising a processor having programmed instructions to find a contention associated with a controller virtual machine within a first predetermined amount of time;

sort a plurality of user virtual machines coupled to the controller virtual machine, wherein sorting the plurality of user virtual machines is based on consumption of each of the plurality of user virtual machines; and

identify a first subset of the plurality of user virtual machines, the first subset of the plurality of user virtual machines satisfies consumption criteria.

11. The apparatus of claim 10, wherein the processor further has programmed instructions to:

delay a second pre-determined amount of time;

identify a second subset of the plurality of user virtual machines, the second subset of the plurality of user virtual machines; and

identify a plurality of bully VMs, the plurality of bully VMs being members of the first subset of the plurality of user virtual machines and the second subset of the plurality of user virtual machines.

12. The apparatus of claim 10, wherein the processor further has programmed instructions to identify a plurality of bully VMs, the plurality of bully VMs being member of the first subset of the plurality of user virtual machines.

13. The apparatus of claim 10, wherein the contention is an input/output (IO) contention.

14. The apparatus of claim 10, wherein finding the contention is based on a central processing unit (CPU) usage of the controller virtual machine.

15. The apparatus of claim 10, wherein the consumption criteria comprises an actual size of the first subset of the plurality of user virtual machines being no more than a predetermined size.

17. The apparatus of claim 10, wherein the consumption criteria comprises a first consumption difference between two neighboring user virtual machines in the first subset of the plurality of user virtual machines, the first consumption difference not being more than a first predetermined threshold.

18. The apparatus of claim 10, wherein the consumption criteria comprises a second consumption difference between a last user virtual machine in the first subset of the plurality of user virtual machines and a first user virtual machine outside the first subset of the plurality of user virtual machines, the second consumption difference being at least a second predetermined threshold.

16. (canceled)

19. A non-transitory computer-readable storage medium having instructions stored thereon that, upon execution by a processor, causes the processor to perform operations comprising:

finding a contention associated with a controller virtual machine within a first predetermined amount of time;
