Program log record optimization

A system for optimizing an application program log record, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• identify an original log method of an application program;
• separate a character string parameter in the original log method into a constant part and a variable part;
• establish a correspondence flag for correlating between the constant part and the variable part;
• generate an optimized log method based on the constant part, the variable part and the correspondence flag;
• replace the original log method with the optimized log method;
• and
• execute the application program and the optimized log method to generate an application program log record based on the optimized log method at least by:
• recording first log information corresponding to the constant part and the correspondence flag into a constant log file;
• and
• recording second log information corresponding to the variable part and the correspondence flag into a variable log file separate from the constant log file without logging the constant part in the variable log file, and wherein the correspondence flag correlates the first log information with the second log information, wherein the first log information corresponding to the constant part is only recorded once in the constant log file, and the second log information corresponding to the variable part is recorded in the variable log file each time generation of an application program log record is triggered, and wherein the constant part, variable part, correspondence flag, first log information, and second log information are distinct.

A computer program product comprising a non-transitory computer readable medium having a computer readable program stored therein, wherein the computer readable program, when executed on a data processing system, causes the data processing system to:

• identify an original log method of an application program;
• separate a character string parameter in the original log method into a constant part and a variable part;
• establish a correspondence flag for correlating between the constant part and the variable part;
• generate an optimized log method based on the constant part, the variable part, and the correspondence flag;
• replace the original log method with the optimized log method;
• and
• execute the application program and the optimized log method to generate an application program log record based on the optimized log method at least by:
• recording first log information corresponding to the constant part and the correspondence flag into a constant log file;
• and
• recording second log information corresponding to the variable part and the correspondence flag into a variable log file separate from the constant log file without logging the constant part in the variable log file, and wherein the correspondence flag correlates the first log information with the second log information, wherein the first log information corresponding to the constant part is only recorded once in the constant log file, and the second log information corresponding to the variable part is recorded in the variable log file each time generation of an application program log record is triggered., and wherein the constant part, variable part, correspondence flag, first log information, and second log information are distinct.
