Abstract

A status notification method and facility is provided for use with a service chain processing a request for a service. The service chain can include multiple computer nodes, and the method includes dynamically creating the service chain for processing the request, and guaranteeing agreement, on at least two of the nodes of the service chain, about the status of the processing of the request. The method can also include saving detailed operational data logs in response to determining that a failure in processing the request has occurred. When a given node in the service chain determines that failure has occurred, agreement about the failure can be propagated throughout the service chain. Also, conditional logging of detailed operational data can minimize the amount of operational data transmitted over a network and saved to a data repository.

Claims

1. A method of operating a computer system comprising computer nodes, the method comprising acts of:

(A) upon receiving a request for a service, creating a service chain for processing the request for the service, wherein the service chain comprises a first plurality of the computer nodes, and wherein the first plurality of the computer nodes is unknown prior to receiving the request for the service; and

(B) guaranteeing agreement, on at least two computer nodes of the first plurality of the computer nodes, about a status of the processing of the request for the service.

2. The method of claim 1, wherein the status of the processing of the request comprises an indication of a success in the processing of the request for the service.

3. The method of claim 1, wherein the status of the processing of the request comprises an indication of a failure in the processing of the request for the service.

4. The method of claim 3, further comprising an act of reporting the failure in the processing of the request for the service.

5. The method of claim 4, wherein the act of reporting the failure in the processing of the request for the service comprises reporting the failure in the processing of the request for the service to a service operations center.

6. The method of claim 3, further comprising an act of saving operational data at least partially in response to the failure in the processing of the request for the service.

7. The method of claim 6, wherein the act of saving operational data comprises providing the operational data to a centralized data repository.

8. The method of claim 7, wherein the operational data comprises performance data at least partially related to the processing of the request for the service.

9. The method of claim 1, wherein the act (B) comprises guaranteeing agreement, on each of the computer nodes of the first plurality of computer nodes, about the status of the processing of the request for the service.

10. The method of claim 1, wherein the act (A) comprises directing the request for the service using at least one network load balancer.

11. A method of operating a computer system comprising computer nodes, the method comprising acts of:

(A) upon receiving a request for a service, creating a service chain for processing the request for the service, wherein the service chain comprises a first plurality of the computer nodes, and wherein the first plurality of the computer nodes is unknown prior to receiving the request for the service; and

(B) saving operational data at least partially in response to a failure in the processing of the request for the service.

12. The method of claim 11, wherein the operational data comprises performance data at least partially related to the processing of the request for the service.

13. The method of claim 11, wherein the act (B) comprises providing the operational data to a centralized data repository.

14. The method of claim 13, further comprising an act of extracting data from the centralized data repository at least partially in response to a query.

15. The method of claim 11, wherein the act (B) comprises saving first operational data associated with a first computer node in the service chain, and saving second operational data associated with a second computer node in the service chain.

16. At least one computer readable medium encoded with a plurality of instructions that, when executed, performs a method of operating a computer system comprising computer nodes, the method comprising acts of:

(A) upon receiving a request for a service, creating a service chain for processing the request for the service, wherein the service chain comprises a first plurality of the computer nodes, and wherein the first plurality of the computer nodes is unknown prior to receiving the request for the service;

(B) guaranteeing agreement, on at least two computer nodes of the first plurality of the computer nodes, about a failure in the processing of the request for the service; and

(C) saving operational data at least partially in response to the failure in the processing of the request for the service.

17. The at least one computer readable medium of claim 16, wherein the method further comprises an act of reporting the failure in the processing of the request for the service.

18. The at least one computer readable medium of claim 16, further comprising an act of determining an occurrence of the failure in the processing of the request for the service at least partially based on exceeding a timeout for receiving a response to the request for the service.

19. The at least one computer readable medium of claim 18, further comprising an act of associating a unique identifier with the request for the service.

20. The at least one computer readable medium of claim 19, wherein the act (B) comprises sending a notification of the failure in the processing of the request for the service from a first computer node in the service chain to a second computer node in the service chain, and wherein the notification comprises the unique identifier.
