Abstract

A method is used in managing system polling. Polling parameters that are based on a set of criteria are determined for receiving updated information for a managed object in a data storage system. Based on the polling parameters, the managed object is polled. Based on the set of criteria, polling parameters are dynamically changed. Based on the results of polling, polling is disabled for the managed object.

Claims

1. A method for use in managing system polling, the method comprising:

determining polling parameters for receiving updated information for a managed object in a data storage system, wherein the polling parameters are based on a set of criteria, wherein the set of criteria includes a set of policies, wherein the set of policies includes a background polling policy, a data usage policy, a health check policy, and a data consumption policy, wherein the polling parameters include detecting updates to the managed object based on the set of policies;

based on the polling parameters, polling the managed object, wherein polling the managed object includes polling configuration data associated with the managed object; and

dynamically changing the polling parameters based on the set of criteria.

2. The method of claim 1, wherein managing system polling further comprises the step of:

based on the results of polling, disabling polling of the managed object.

3. The method of claim 1, wherein the polling parameters comprises polling frequency.

4. The method of claim 1, further comprising:

ignoring a request to poll a managed object upon determining that the request is a duplicate request.

5. The method of claim 1, further comprising:

changing a polling frequency based on time taken to poll the managed object previously.

6. The method of claim 1, wherein the set of criteria comprises a set of conditions and a set of policies.

7. The method of claim 6, wherein the set of policies includes a health check policy indicating a polling frequency for receiving updated information for a managed object in a data storage system.

8. The method of claim 7, further comprising:

disabling polling of a managed object upon receiving unrecoverable errors on polling the managed object based on the health check policy; and

enabling polling of the managed object upon resolution of the unrecoverable errors.

9. The method of claim 6, wherein the set of policies includes a background polling policy indicating a polling frequency for periodically receiving updated information for a managed object in a data storage system.

10. The method of claim 6, wherein the set of policies includes a client data usage policy indicating monitoring of updates to information for a managed object in a data storage system.

11. The method of claim 10, further comprising:

changing a polling frequency upon detecting updates to a managed object based on the client data usage policy.

12. The method of claim 6, wherein the set of policies includes a data consumption policy indicating monitoring of access to information for a managed object in a data storage system.

13. The method of claim 12, further comprising:

polling a managed object upon detecting access to updated information for the managed object based on the data consumption policy.

14. A system for use in managing system polling, the system comprising:

a processor;

first logic determining polling parameters for receiving updated information for a managed object in a data storage system, wherein the polling parameters are based on a set of criteria, wherein the set of criteria includes a set of policies, wherein the set of policies includes a background polling policy, a data usage policy, a health check policy, and a data consumption policy, wherein the polling parameters include detecting updates to the managed object based on the set of policies;

second logic polling, based on the polling parameters, the managed object wherein polling the managed object includes polling configuration data associated with the managed object; and

third logic dynamically changing, based on the set of criteria, the polling parameters.

15. The system of claim 14, further comprising

fourth logic disabling, based on the results of polling, polling of the managed object.

16. The system of claim 14, wherein the polling parameters comprises polling frequency.

17. The system of claim 14, wherein the set of criteria comprises a set of conditions and a set of policies.

18. The system of claim 17, wherein the set of policies includes a health check policy indicating a polling frequency for receiving updated information for a managed object in a data storage system.

19. The system of claim 17, wherein the set of policies includes a background polling policy indicating a polling frequency for periodically receiving updated information for a managed object in a data storage system.

20. The system of claim 17, wherein the set of policies includes a client data usage policy indicating monitoring of updates to information for a managed object in a data storage system and a data consumption policy indicating monitoring of access to information for a managed object in a data storage system.
