Abstract

Under the present invention, the performance of a set of system resources is monitored in response to incoming request traffic. When a system resource is approaching an overload condition, a corrective action is identified and implemented. Overload thresholds for each system resource and appropriate corrective actions are contained within a management policy. Based on a performance history of the corrective actions, the management policy can be changed/revised.

Claims

1. A resource-aware computer system for managing request traffic based on a management policy, comprising:

an analyzer system executing in memory by a processor of a computer and configured for monitoring a performance of a set of system resources in response to the request traffic, and for determining when at least one of the set of system resources is approaching an overload condition based on the management policy; and

a planning system also executing in memory by a processor of a computer and configured for identifying a corrective action to avoid the overload condition, wherein the corrective action is identified based on the at least one system resource that is approaching the overload condition and the management policy.

2. The system of claim 1, wherein the planning system further implements the corrective action.

3. The system of claim 2, further comprising a learning system for changing the management policy based on a performance history of the implemented corrective action.

4. The system of claim 3, wherein the learning system works in conjunction with the analyzer system to monitor the performance history of the implemented corrective action.

5. The system of claim 1, wherein the management policy contains overload thresholds and corrective actions to be taken.

6. The system of claim 1, wherein the corrective action comprises adjusting a queue priority of a type of request in the request traffic based on the at least one system resource that is approaching the overload condition.

7. The system of claim 1, wherein the corrective action comprises excluding at least one request in the request traffic based on the at least one system resource that is approaching the overload condition.

8. The system of claim 1, wherein the corrective action comprises limiting a type of request in the request traffic based on a consumption of the at least one system resource that is approaching the overload condition.

9. The system of claim 1, wherein the set of system resources includes system resources selected from the group consisting of a storage device, a server and a network.

10. A resource-aware method for managing request traffic based on a management policy, comprising:

receiving the request traffic;

monitoring a performance of a set of system resources in response to the request traffic;

determining when at least one of the set of system resources is approaching an overload condition based on the management policy; and

identifying a corrective action to avoid the overload condition based on the at least one system resource that is approaching the overload condition and the management policy.

11. The method of claim 10, further comprising changing the management policy based on a performance history of the corrective action.

12. The method of claim 10, wherein the management policy contains overload thresholds and corrective actions to be taken.

13. The method of claim 10, wherein the corrective action comprises adjusting a queue priority of a type of request in the request traffic based on the at least one system resource that is approaching the overload condition.

14. The method of claim 10, wherein the corrective action comprises excluding at least one request in the request traffic based on the at least one system resource that is approaching the overload condition.

15. The method of claim 10, wherein the corrective action comprises limiting a type of request in the request traffic based on a consumption of the at least one system resource that is approaching the overload condition.

16. The method of claim 10, further comprising implementing the identified corrective action.

17. The method of claim 10, wherein the set of system resources includes system resources selected from the group consisting of a storage device, a server and a network.

18. A program product stored on a recordable computer usable storage medium for managing request traffic based on a management policy, which when executed comprises:

program code for monitoring performance of a set of system resources in response to incoming request traffic, and for determining when one of the set of system resources is approaching an overload condition based on the management policy; and

program code for identifying and implementing a corrective action to avoid the overload condition, wherein the corrective action is identified based on the system resource that is approaching the overload condition and the management policy.

19. The program product of claim 18, further comprising program code for changing the management policy based on a performance history of the corrective action.

20. The program product of claim 19, wherein the program code for changing the management policy works in conjunction with the program code for monitoring to monitor the performance history of the corrective action.

21. The program product of claim 18, wherein the management policy contains overload thresholds and corrective actions to be taken.

22. The program product of claim 18, wherein the corrective action comprises adjusting a queue priority of a type of request in the request traffic based on the system resource that is approaching the overload condition.

23. The program product of claim 18, wherein the corrective action comprises excluding at least one request in the request traffic based on the system resource that is approaching the overload condition.

24. The program product of claim 18, wherein the corrective action comprises limiting a type of request in the request traffic based on a consumption of the at least one system resource that is approaching the overload condition

25. The program product of claim 18, wherein the set of system resources includes system resources selected from the group consisting of a storage device, a server and a network.
