Abstract

A method, program, and system for dynamically configuring logging elements in a computer system are provided. The invention comprises a logging subsystem within the computer system, wherein the subsystem contains a plurality of logging elements which record events within the computer system. Inheritance relationships are established for the logging elements, which allows the logging elements to be configured either individually or as a group. The logging elements are then configured to record specified types of events and send the logging data of the events to specified locations within the computer system. In one embodiment of the present invention, the computer system is one of a plurality of nodes in a distributed computer network, wherein logging elements within a one network node can be remotely configured from a another node in the network.

Claims

1. A method for dynamically configuring logging elements in a computer system, the method comprising:

initializing a logging subsystem within the computer system, the logging subsystem comprising a plurality of logging elements which record events within the computer system;

establishing inheritance relationships for properties of the logging elements within the logging subsystem, wherein the inheritance relationships allow the logging elements to be configured both individually and as a group; and

configuring the logging elements to record specified types of events and send the logging data of the events to specified locations within the computer system;

wherein the computer system is one of a plurality of nodes in a distributed computer network, wherein logging elements within a first node in the computer network can be remotely configured from a second node in the computer network.

2. The method according to claim 1, wherein the logging elements comprise at least one of the following:

message logger;

trace logger;

logging handler;

logging formatter;

logging filter; and

log manager.

3. The method according to claim 1, further comprising reconfiguring an individual logging element to send logging data to a new location, in addition to the location specified in the original configuration of that logging element.

4. The method according to claim 1, further comprising creating a taskID which follows a logging task across multiple components until completion.

5. The method according to claim 1, wherein the logging elements are configured by means of a command line interface.

6. The method according to claim 1, wherein the logging elements are configured by means of a graphical user interface.

7. The method according to claim 1, further comprising remotely reconfiguring a logging element to send logging data to at least one other node in the distributed computer network, in addition to the location specified in the original configuration of that logging element.

8. The method according to claim 7, further comprising a taskID which follows a logging task across multiple nodes until completion

9. The method according to claim 1, further comprising:

establishing inheritance relationships between nodes in the distributed computer network, wherein the inheritance relationships allows logging elements to be remotely configured both within individual nodes and across multiple nodes.

10. The method according to claim 1, further comprising:

configuring logging elements within a plurality of nodes to send logging data to a designated logging server which places the logging data into a single logging database.

11. The method according to claim 10, further comprising:

configuring a plurality of logging servers to send the data in their respective logging databases to a second tier logging server.

13. The computer program product according to claim 12, wherein the logging elements comprise at least one of the following:

message logger;

trace logger;

logging handler;

logging formatter;

logging filter; and

log manager.

14. The computer program product according to claim 12, further comprising instructions for reconfiguring an individual logging element to send logging data to a new location, in addition to the location specified in the original configuration of that logging element.

15. The computer program product according to claim 12, further comprising instructions for creating a taskID which follows a logging task across multiple components until completion.

16. The computer program product according to claim 12, wherein the logging elements are configured by means of a command line interface.

17. The computer program product according to claim 12, wherein the logging elements are configured by means of a graphical user interface.

18. The computer program product according to claim 12, further comprising instructions for remotely reconfiguring a logging element to send logging data to at least one other node in the distributed computer network, in addition to the location specified in the original configuration of that logging element.

19. The computer program product according to claim 18, further comprising a taskID which follows a logging task across multiple nodes until completion

20. The computer program product according to claim 12, further comprising:

instructions for establishing inheritance relationships between nodes in the distributed computer network, wherein the inheritance relationships allows logging elements to be remotely configured both within individual nodes and across multiple nodes.

21. The computer program product according to claim 12, further comprising:

instructions for configuring logging elements within a plurality of nodes to send logging data to a designated logging server which places the logging data into a single logging database.

22. The computer program product according to claim 21, further comprising:

instructions for configuring a plurality of logging servers to send the data in their respective logging databases to a second tier logging server.

12. A computer program product in a computer readable medium, for dynamically configuring logging elements in a computer system, the computer program product comprising:

instructions for initializing a logging subsystem within the computer system, the logging subsystem comprising a plurality of logging elements which record events within the computer system;

instructions for establishing inheritance relationships for properties of the logging elements within the logging subsystem, wherein the inheritance relationships allow the logging elements to be configured both individually and as a group; and

instructions for configuring the logging elements to record specified types of events and send the logging data of the events to specified locations within the computer system;

wherein the computer system is one of a plurality of nodes in a distributed computer network, wherein logging elements within a first node in the computer network can be remotely configured from a second node in the computer network.

23. A system for dynamically configuring logging elements in a computer system, the system comprising:

a logging subsystem within the computer system, the logging subsystem comprising a plurality of logging elements which record events within the computer system;

a register which establishes inheritance relationships for properties of the logging elements within the logging subsystem, wherein the inheritance relationships allow the logging elements to be configured both individually and as a group; and

a configuring component which configures the logging elements to record specified types of events and send the logging data of the events to specified locations within the computer system;

wherein the computer system is one of a plurality of nodes in a distributed computer network, wherein logging elements within a first node in the computer network can be remotely configured from a second node in the computer network.
