Abstract

One aspect of the invention is a method for providing real-time feedback regarding the effect of applying a policy definition used for management in a computing system. An example of the method includes receiving the policy definition, and accessing stored information regarding at least one managed entity in the computing system. This example also includes applying the policy definition to the information regarding the at least one managed entity. This example further includes outputting information providing real-time feedback regarding the effect of applying the policy definition to the information regarding the at least one managed entity. Another aspect of the invention is a method for defining a policy used for management in a computing system.

7. The method of claim 1, wherein the information providing realtime feedback is outputted substantially immediately after implementation of the policy.

8. The method of claim 1, wherein the information providing real-time feedback is outputted within 10 seconds from when the policy definition is received.

a memory entity;

a CPU entity.

13. A computing system, comprising:

a memory; and

a processing device coupled to the device, wherein the processing device is programmed to perform operations for providing real-time feedback regarding the effect of applying a policy definition used for management in the computing system, the operations comprising;

receiving a policy definition;

accessing stored information regarding managed entities in the computing system, wherein the information includes for the managed entities attributes of resources maintained by the managed entities, and wherein the policy definition specifies at least one operation to perform based on a condition with respect to at least one of the attributes of at least one of the resources maintained by at least one of the managed entities;

applying the policy definition to the information regarding the managed entities to determine whether the attributes of the resources of the managed entities satisfy the condition of the policy definition;

providing real-time feedback regarding the effect of applying the policy definition to the information regarding the managed entities, wherein the effect for the managed entities comprises results of performing the at least one operation with respect to the managed entities whose attribute of the resource satisfies the condition of the policy definition; and

displaying, as part of providing the real-time feedback, information on a GUI indicating host machines and filesystems that will be affected if the policy definition is implemented, and displaying a file tree on the GUI wherein resources of the managed entities affected by the policy definition are highlighted.

14. The computing system of claim 13:

wherein the policy definition specifies that a reclaim operation should be performed for a tape storage system if unused space exceeds 40%;

and wherein the operations farther comprise;

repeating the operations of receiving the policy definition, accessing the stored information, applying the policy definition, providing the real-time feedback, and displaying information on the GUI, wherein the policy definition specifies that a reclaim operation should be performed for a tape storage system if unused space exceeds 60%; and

comparing the effects of the policy definition that specifies that a reclaim operation should be performed for a tape storage system if unused space exceeds 40% with the policy definition that specifies that a reclaim operation should be performed for a tape storage system if unused space exceeds 60%.
