Abstract

Systems and methods are disclosed for managing information technology resources. Management capabilities available for a particular IT resource are defined via at least one management interface. The management interface includes port types that specify attributes and operations available in a Web service to manage the IT resource. The port types are mapped to descriptors in a ModelMBeanInfo interface than can be used with an MBean that corresponds to the Web service.

Claims

1. A system for managing diverse information technology (IT) resources, comprising:

an agent controller executable on a computer processor, wherein the agent controller includes an MBean server configured with at least one MBean, further wherein the at least one MBean correlates to a managed object that represents a Web service, and the Web service includes features for managing at least one of the IT resources;

a handler executable on a computer processor and configured to communicate with a management application and the agent controller, wherein the handler is operable to;

receive a request message from the management application and transmit a response message to the management application;

translate the request message to determine the Web service being requested by the management application; and

determine whether the Web service being requested is available by correlating the Web service name to information in a descriptor of at least one MBean in the MBean server, wherein the information in the descriptor is based on a management interface for the managed object.

2. The system of claim 1, wherein the information in the descriptor includes a parameter indicating whether the Web service should be published for access by the management application.

3. The system of claim 1, further comprising a handler, wherein the requests pertain to at least one of the group of:

setting an attribute of the managed object, getting an attribute of the managed object, and invoking an operation included in the managed object.

4. The system of claim 1, wherein the descriptor includes an indicator of whether the ModelMBean is compliant with Web Services Management Framework (WSMF) management interfaces.

5. The system of claim 1, wherein the descriptor includes a map of port type names to Web service resource properties.

6. The system of claim 1, wherein the descriptor includes a parameter that indicates the level of visibility of the MBean.

7. The system of claim 1, wherein the descriptor includes information regarding the identity of the managed object, and operations and attributes that are available in the managed object.

8. The system of claim 1, wherein the descriptor includes information regarding the namespace for a Web Service Description Language (WSDL) document that defines the management interface.

9. The system of claim 1, wherein the descriptor includes information regarding whether the MBean is to be placed in persistent storage.

10. The system of claim 1, wherein the descriptor includes information regarding the role of an operation including at least one of an attribute getter, an attribute setter, and an operation invoker.

11. The system of claim 1, wherein the descriptor includes information regarding the management interface category corresponding to a port type.

12. The system of claim 1, wherein the descriptor includes information regarding a notification that can be issued by the Web service to the management application.

13. The system of claim 1, wherein the handler communicates with the management application via a communication network.

14. The system of claim 1, further comprising a configuration file that specifies a Web service directory for Web services registered in the MBean server.

15. The system of claim 1, further comprising a configuration file that specifies a notification manager that handles notifications and subscriptions for MBeans registered in the MBean server.

16. The system of claim 1, further comprising a configuration file that specifies a relationship service, wherein the relationship service allows the managed object to maintain a list of relationships with other managed objects.

17. The system of claim 1, further comprising a configuration file that specifies a collections service, wherein the collections service supports features in the management interface that aggregate responses from multiple managed objects.

18. The system of claim 1, further comprising a configuration file that specifies a discovery strategy to find managed objects in the system.

19. The system of claim 1, further comprising a configuration file that specifies the name of the MBean server in which the ModelMBean is to be registered.

20. The system of claim 1, further comprising a configuration file that specifies a list of discovery objects that should complete before a specified discovery object is executed.

21. The system of claim 1, further comprising a configuration file that specifies whether external discovery of MBeans is enabled.

22. The system of claim 1, further comprising a configuration file that specifies publication information for the Web service.

23. The system of claim 1, further comprising a configuration file that specifies the location where an interface description of the management interface is stored, wherein the interface description is accessible by the management application to determine the Web services that are available for the corresponding IT resource.

24. The system of claim 1, wherein the messages are transmitted to and from the handler using the Simple Object Access Protocol (SOAP).

25. The system of claim 1, wherein the handler is a JAX-RPC handler.

26. A method for managing IT resources comprising:

defining management capabilities available for a particular IT resource via at least one management interface, wherein the management interface includes port types that specify attributes and operations available in a Web service to manage the IT resource; and

mapping the port types to descriptors in a ModelMBeanInfo interface than can be used with an MBean that corresponds to the Web service.

27. The method of claim 26, further comprising discovering MBeans in remote processing environments and registering the discovered MBeans in a MBean server.

28. The method of claim 26, further comprising determining relationships between a managed object representing the Web service and other managed objects representing other Web services.

29. The method of claim 26, further comprising accessing a configuration file that includes information regarding publishing the MBean.

30. The method of claim 26, further comprising accessing a configuration file that includes information regarding emitting events.

31. An apparatus for managing IT resources, comprising:

means for determining management capabilities available for a particular IT resource via at least one management interface, wherein the management interface includes port types that specify attributes and operations available in a Web service to manage the IT resource;

means for mapping the port types to descriptors in a ModelMBeanInfo interface than can be used with an MBean that corresponds to the Web service;

means for registering the MBean in an MBean server;

means for determining relationships between a managed object representing the Web service and other managed objects representing other Web services.

32. The apparatus as set forth in claim 31, further comprising:

means for generating an interface description based on the management interface, wherein a remote management application can access the interface description to determine management features available for a particular IT resource.
