Abstract

Unifying application log messages using runtime instrumentation includes capturing raw data associated as a log message from an application using an application monitoring module, determining if the raw data is to be filtered based on a filtering configuration, and constructing a log message based on the raw data. A system for unifying application log messages using runtime instrumentation includes a capture engine to capture raw data associated as a log message from an application using an application monitoring module, a determination engine to determine if the raw data is to be filtered based on a filtering configuration, a construction engine to construct a log message based on the raw data, and a log framework monitor engine to monitor an application program interface that invokes a writing action of the log message using at least one log framework to capture the log message in real time.

Claims

1. A method for unifying application log messages using runtime instrumentation, the method comprising:

capturing raw data associated as a log message from an application using an application monitoring module;

determining if said raw data is to be filtered based on a filtering configuration; and

constructing a log message based on said raw data.

2. The method of claim 1, in which capturing said raw data associated as said log message from said application using said application monitoring module comprises intercepting an execution of program code of said application at a log message generation event.

3. The method of claim 1, further comprising monitoring an application program interface that invokes a writing action of said log message using at least one log framework to capture said log message.

4. The method of claim 3, further comprising modifying program code of said application to allow said application monitoring module to monitor when said application is writing said log message via the at least one said log framework.

5. The method of claim 4, further comprising monitoring at least one log level on said log message using at least one said log framework to determine said filter configuration,

in which said filter configuration comprises determining if a number of log levels are enabled or disabled in the log message and filtering the log message if a predetermined log level is enabled allowing the system to implement a different filtering mechanism than the filtering mechanisms associated with the application.

6. The method of claim 1, in which constructing said log message based on said raw data comprising adding an argument to said log message in real time.

7. The method of claim 6, further comprising formatting said log message,

in which formatting said log message comprises adding a prefix to said log message, and

in which said prefix comprises a stack trace, a date time, a process identification, or combinations thereof.

8. A system for unifying application log messages using runtime instrumentation, the system comprising:

a capture engine to capture raw data associated as a log message from an application using an application monitoring module;

a determination engine to determine if said raw data is to be filtered based on a filtering configuration;

a construction engine to construct a log message based on said raw data; and

a log framework monitor engine to monitor an application program interface that invokes a writing action of said log message using at least one log framework to capture said log message in real time.

9. The system of claim 8, in which said construction engine further constructs a log message by adding an argument to said log message in real time.

10. The system of claim 9, further comprising a format engine to format said log message,

in which said format engine adds a prefix to said log message, and

in which said prefix comprises a stack trace, a date time, a process identification, or combinations thereof.

11. The system of claim 8, in which said log framework monitor engine further monitors a log level using said at least one log framework to determine said filter configuration.

12. The system of claim 8, in which said capture engine further intercepts an execution of said program code of said application at a predefined event.

13. A computer program product for unifying application log messages using runtime instrumentation, comprising:

a tangible non-transitory computer readable storage medium, said tangible non-transitory computer readable storage medium comprising computer readable program code embodied therewith, said computer readable program code comprising program instructions that, when executed, causes at least one processor to;

capture raw data associated as a log message from an application when the application invokes a predetermined application programming interface using an application monitoring module; and

construct a log message based on said raw data.

14. The computer program product of claim 13, further comprising computer readable program code comprising program instructions that, when executed, cause said processor to intercept an execution of program code of said application at a predefined event associated with an invocation of a write action associated with the application programming interface.

15. The computer program product of claim 13, further comprising computer readable program code comprising program instructions that, when executed, cause said processor to construct the log message by adding an argument to said raw data in real time.
