A technique for logging tasks in a computer system. Tasks are logged into the computer system by executing at least one task at the computer system. A set of log metadata and a set of log levels of log records of the at least one task may be determined from an execution log output of the at least one task. Execution outputs of a further task may be determined according to the determined set of log metadata and associated set of log levels.

Task-specific logging in digital computer systems

The present disclosure relates to generating an event specific log file for a computer system. The generation comprises storing buffered log data in at least one memory buffer during an execution of one or more threads in real time. The generation further comprises receiving thread execution data. The generation further comprises inputting the thread execution data into an anomalous program event detector module configured to generate an anomalous program event signal in response to detecting an anomalous program execution event. The generation further comprises searching 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 signal. The method further comprises writing the event specific log data to an event specific log file using a log archive writer module.
