Event specific log file generation

A computer program product for generating an event specific log file for a computer system, 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, the program instructions comprising:
• program instruction to store buffered log data in at least one memory buffer during an execution of one or more threads in real time;
• program instruction to receive thread execution data descriptive of the execution of the one or more threads in real time;
• program instruction to input the thread execution data into an anomalous program event detector module, wherein the anomalous program event detector module is configured to detect an anomalous program execution event in the thread execution data;
• and wherein the anomalous program event detector module is further configured to generate an anomalous program event signal in response to detecting the anomalous program execution event in the thread execution data;
• program instruction to search the buffered log data for event specific log data in the at least one memory buffer with a log dependency analyzer module in response to the anomalous program event detector module generating the anomalous program event signal, wherein the log dependency analyzer module is configured for selecting event specific log data from the buffered log data specified by the anomalous program execution event;
• and wherein the log dependency analyzer module is configured to dynamically select the event specific log data by the content of in-memory buffers indicated in the anomalous program execution event;
• and
• program instruction to write the event specific log data to an event specific log file using a log archive writer module configured to format the event specific log data as the event specific log file.
