Abstract

A computer program product comprises a computer useable medium. The computer useable medium has a computer readable program such that when the computer readable medium is executed on a computer, the computer is caused to configure a calling interceptor at a service invocation point corresponding to a first component service of a software application to monitor a service invocation made by the first component service of a second component service of the software application, record a first set of correlation data represented by a first correlation indicator into a trace file, record a unique identifier into the trace file, and send the unique identifier to the second component service thought the service invocation.

Claims

1. A computer program product comprising a non-transitory computer useable storage device having a computer readable program stored thereon, wherein the computer readable program when executed on a computer causes the computer to:

configure a calling interceptor at a first component service to monitor a first service invocation made by the first component service to a second component service, record first data represented by a first correlation indicator and an identifier into a trace file, and send the identifier to the second component service, wherein a callee interceptor at the second component service records second data represented by a second correlation indicator and the identifier into the trace file;

configure a callee interceptor at the first component service to monitor a second service invocation made by the second component service to the first component service and record third data represented by a third correlation indicator into the trace file; and

correlate the first data, the second data, and the third data in the trace file based on the first correlation indicator, the second correlation indicator, the third correlation indicator, and the identifier.

2. The computer program product of claim 1, wherein at least one of the first service invocation and the second service invocation is asynchronous.

3. The computer program product of claim 1, wherein the first component service is stored in a first component and the second component service is stored in a second component, the first component distinct from the second component.

4. The computer program product of claim 1, wherein the first component service is stored in a first server and the second component service is stored in a second server, the first server distinct from the second server.

5. The computer program product of claim 1, wherein the computer readable program when executed on the computer further causes the computer to process the first service invocation at the first component service utilizing a first thread and process the second service invocation at the second component service utilizing a second thread, the first thread distinct from the second thread.

6. The computer program product of claim 1, wherein the computer readable program when executed on the computer further causes the computer to display the correlated first data, second data, and third data.

7. The computer program product of claim 1, wherein the computer readable program when executed on the computer further causes the computer to randomly generate the identifier.

8. The computer program product of claim 1, wherein the computer readable program when executed on the computer further causes the computer to process a plurality of events and record a unique event identifier for each event in the trace file.

9. The computer program product of claim 8, wherein correlating the first data and the second data is based on the unique event identifier.

10. The computer program product of claim 8, wherein the computer readable program when executed on the computer further causes the computer to randomly generate the unique event identifier.

11. The computer program product of claim 1, wherein the computer readable program is built on top of a Service Oriented Architecture.

12. A method comprising:

configuring, using at least one processor of a computer, a calling interceptor at a first component service to monitor a first service invocation made by the first component service to a second component service, record first data represented by a first correlation indicator and an identifier into a trace file, and send the identifier to the second component service, wherein a callee interceptor at the second component service records second data represented by a second correlation indicator and the identifier into the trace file;

configuring, using at least one processor of the computer, a callee interceptor at the first component service to monitor a second service invocation made by the second component service to the first component service and record third data represented by a third correlation indicator into the trace file; and

correlating, using at least one processor of the computer, the first data, the second data, and the third data in the trace file based on the first correlation indicator, the second correlation indicator, the third correlation indicator, and the identifier.

13. The method of claim 12, wherein at least one of the first service invocation and the second service invocation is asynchronous.

14. The method of claim 12, wherein the first component service is stored in a first component and the second component service is stored in a second component, the first component distinct from the second component.

15. The method of claim 12, wherein the first component service is stored in a first server and the second component service is stored in a second server, the first server distinct from the second server.

16. The method of claim 12, further comprising processing the first service invocation at the first component service utilizing a first thread and processing the second service invocation at the second component service utilizing a second thread, the first thread distinct from the second thread.

17. The method of claim 12, further comprising displaying the correlated first data, second data, and third data.

18. A system comprising:

a processor; and

storage coupled to the processor, wherein the storage has stored thereon a computer readable program, and wherein the processor is configured to execute the computer readable program to perform;

configuring a calling interceptor at a first component service to monitor a first service invocation made by the first component service to a second component service records first data represented by a first correlation indicator and an identifier into a trace file, and sends the identifier to the second component service, wherein a callee interceptor at the second component service records second data represented by a second correlation indicator and the identifier into the trace file;

configuring a callee interceptor at the first component service to monitor a second service invocation made by the second component service to the first component service and record third data represented by a third correlation indicator into the trace file; and

correlating the first data, the second data, and the third data in the trace file based on the first correlation indicator, the second correlation indicator, the third correlation indicator, and the identifier.

19. The system of claim 18, wherein at least one of the first service invocation and the second service invocation is asynchronous.

20. The system of claim 18, further comprising a display module that displays the correlated first data, second data, and third data.
