Abstract

To maintain and manage a computer network, a system administrator may monitor a large number and variety of components, each component comprising a variety of resources. The instrumentation of a resource may be monitored and/or manipulated by receiving a Simple Object Accessing Protocol (SOAP) message comprising an operation identifier for accessing instrumentation information and a resource identifier associated with a computer system resource. The management system may resolve the resource identifier into an address for a local handler associated with the resource, and may send a local request to the local handler at the resolved address.

Claims

1. A computer storage medium having computer executable instructions for performing steps comprising:

(a) receiving from a sending device at a receiving device a first Simple Object Accessing Protocol (SOAP) message comprising a first operation identifier for accessing instrumentation information and a first resource identifier associated with a first computer system resource;

(b) resolving the first resource identifier into an address for a local handler associated with the first resource;

(c) sending a local request to the local handler at the resolved address;

(d) determining a timeout period for the first Simple Object Accessing Protocol message, the timeout period being a published default timeout period, the timeout period not being part of the first Simple Object Accessing Protocol message, determining the timeout period including requesting the published timeout period from a publishing device, the publishing device being different from the sending device and the receiving device; and

(e) when the receiving device cannot comply with the timeout period, sending an Unsupported Timeout message to the sending device.

2. The computer storage medium of claim 1, wherein the first resource identifier includes a Uniform Resource Identifier.

3. The computer storage medium of claim 1, wherein the first resource identifier includes a CIM.

4. The computer storage medium of claim 1, further comprising determining a schema for communicating with the local handler, and generating the local request from the SOAP message and the accessed schema.

5. The computer storage medium of claim 1, further comprising receiving the instrumentation information from the local handler, and sending to a client manager a SOAP response comprising the instrumentation information.

6. The computer storage medium of claim 1, further comprising authenticating the first SOAP message using hypertext transport protocol secure (HTTPS).

7. The computer storage medium of claim 1, wherein the first operation identifier includes at least one of a group consisting of a get identifier, a put identifier, a create resource identifier, a delete resource identifier, an enumerate identifier, a pull identifier, a release identifier, an open shell identifier, a close shell identifier, a control shell identifier, a command result identifier, a subscribe identifier, an unsubscribe identifier, a renew subscription identifier, a event batch identifier, and a trap identifier.

8. The computer storage medium of claim 1, further comprising receiving a second SOAP message comprising a second operation identifier for accessing instrumentation information and a second resource identifier associated with a second computer system resource, wherein the first operation identifier includes at least one of the a group consisting of a get request, a put request, a delete request, and a create request, and the second operation identifier includes at least one of a group consisting of a subscribe identifier, an unsubscribe identifier, an event batch identifier, and a trap identifier.

9. The computer storage medium of claim 8, further comprising authenticating the first SOAP message and the second SOAP message with a consistent authentication scheme.

10. A computer storage medium having computer executable instructions for performing steps comprising:

(a) sending from a client manager to a resource agent a first Simple Object Accessing Protocol (SOAP) request comprising an first operation identifier for retrieving instrumentation information and a resource identifier indicating a resource that is the source of the instrumentation information;

(b) receiving at the client manager a first SOAP response comprising a first value of the instrumentation information of the resource;

(c) sending from the client manager a second SOAP request comprising a second operation identifier for correcting instrumentation information, the resource identifier, and a second value of the instrumentation information, the second SOAP request requesting that the first value be replaced by the second value in the resource associated with the resource identifier; and

(d) receiving at the client manager a second SOAP response, the second SOAP response being in response to the second SOAP request and indicating that the first value has been replaced by a third value instead of the second value in the resource associated with the resource identifier, the third value being different from the second value.

11. The computer storage medium of claim 10, further comprising receiving a second SOAP response verifying that the first value has been replaced by the second value in the resource associated with the resource identifier.

12. The computer storage medium of claim 10, wherein the resource identifier includes a uniform resource identifier (URI).

13. The computer storage medium of claim 10, wherein the first value is a singleton value.

14. The computer storage medium of claim 10, wherein the first value is an enumeration sequence.

15. The computer storage medium of claim 10, wherein the first operation identifier includes a namespace of a governing standard and a name of the operation.

16. The computer storage medium of claim 10, further comprising determining the type of instrumentation information of the second value.

17. The computer storage medium of claim 10, further comprising sending a fault response if the type of instrumentation information is not read-write accessible.

18. A computer storage medium having computer executable instructions for performing steps comprising:

(a) receiving a request message comprising an operation identifier for accessing instrumentation information, an address of a resource agent, and a uniform resource identifier identifying a computer system resource associated with the resource agent;

(b) resolving the uniform resource identifier into an address for a local handler associated with the resource;

(c) sending a local request to the local handler at the resolved address;

(d) receiving resource instrumentation information;

(e) determining based on a maximum time value in the request message, the maximum time value indicating a maximum time and not a set of requested information whether the maximum time for the resource agent to respond is zero; and

(f) sending, in response to the local request, only cached results in response to determining the maximum time for the resource agent to respond is zero.
