Abstract

Software that performs the following steps: (i) receiving first bundle information relating to the content of a bundle at a first time, wherein the bundle relates to one or more resources in an application of a distributed computing environment; (ii) monitoring the bundle for a bundle event, wherein the bundle event is generated from a change in a lifecycle state of the bundle; (iii) determining that the bundle event has occurred; (iv) responsive to determining that the bundle event has occurred, receiving second bundle information relating to the content of the bundle at a second time; and (v) responsive to receiving the second bundle information, identifying a granular event associated with the bundle event, wherein the granular event relates to a difference between the first bundle information and the second bundle information.

Claims

1. A computer program product, the computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media for execution by one or more processors, the program instructions comprising;

program instructions to receive first bundle information relating to the content of a bundle at a first time, wherein the bundle relates to one or more resources in an application of a distributed computing environment;

program instructions to monitor the bundle for a bundle event, wherein the bundle event is generated from a change in a lifecycle state of the bundle;

program instructions to determine that the bundle event has occurred;

program instructions to, responsive to determining that the bundle event has occurred, receive second bundle information relating to the content of the bundle at a second time; and

program instructions to, responsive to receiving the second bundle information, identify a granular event associated with the bundle event, wherein the granular event relates to a difference between the first bundle information and the second bundle information.

2. The computer program product of claim 1, wherein the program instructions to identify the granular event associated with the bundle event comprise:

program instructions to compare the first bundle information relating to the content of the bundle at the first time and the second bundle information relating to the content of the bundle at the second time.

3. The computer program product of claim 2, wherein the first bundle information includes a first set of metadata pertaining to the bundle and the second bundle information includes a second set of metadata pertaining to the bundle.

4. The computer program product of claim 1, wherein the program instructions stored on the one or more computer readable storage media further comprise:

program instructions to process the identified granular event to create a notification; and

program instructions to notify a subscriber with the created notification.

5. The computer program product of claim 1, wherein the bundle is implemented in a Java environment.

6. The computer program product of claim 5, wherein:

the bundle is further implemented in an Open Service Gateway initiative (OSGi) for the Java environment; and

the bundle includes at least one of the following;

a dynamically loadable Java class file, and a configuration file declaring external dependencies.

7. The computer program product of claim 1, wherein the program instructions to identify the granular event associated with the bundle event comprise:

program instructions to manage changes in lifecycle states of the bundle, using the granular event associated with the bundle event and the bundle event; and

program instructions to manage applications of the distributed computing environment, using the granular event associated with the bundle event, the bundle event, and subscribers for the bundle event.

8. A computer system comprising:

one or more computer processors;

one or more computer readable storage media;

program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising;

program instructions to receive first bundle information relating to the content of a bundle at a first time, wherein the bundle relates to one or more resources in an application of a distributed computing environment;

program instructions to monitor the bundle for a bundle event, wherein the bundle event is generated from a change in a lifecycle state of the bundle;

program instructions to determine that the bundle event has occurred;

program instructions to, responsive to determining that the bundle event has occurred, receive second bundle information relating to the content of the bundle at a second time; and

program instructions to, responsive to receiving the second bundle information, identify a granular event associated with the bundle event, wherein the granular event relates to a difference between the first bundle information and the second bundle information.

9. The computer system of claim 8, wherein the program instructions to identify the granular event associated with the bundle event comprise:

program instructions to compare the first bundle information relating to the content of the bundle at the first time and the second bundle information relating to the content of the bundle at the second time.

10. The computer system of claim 9, wherein the first bundle information includes a first set of metadata pertaining to the bundle and the second bundle information includes a second set of metadata pertaining to the bundle.

11. The computer system of claim 8, wherein the program instructions stored on the one or more computer readable storage media further comprise:

program instructions to process the identified granular event to create a notification; and

program instructions to notify a subscriber with the created notification.

12. The computer system of claim 8, wherein the bundle is implemented in a Java environment.

13. The computer system of claim 12, wherein:

the bundle is further implemented in an Open Service Gateway initiative (OSGi) for the Java environment; and

the bundle includes at least one of the following;

a dynamically loadable Java class file, and a configuration file declaring external dependencies.
