Capturing task traces for multiple tasks

Abstract:

Method and system are provided for capturing task traces for multiple tasks. The method includes capturing in a task trace structure recent trace data entries for a task of multiple tasks segmented into a predefined number of available blocks, wherein a task trace structure is provided for each of multiple tasks in parallel, wherein trace data entries are written to a block with a timestamp of the trace data entries. The method also includes storing in a global trace structure pushed blocks from the multiple task trace structures of older data that exceed the predefined number of blocks of the task trace structures, wherein the blocks are ordered in the global trace structure by the pushed order of the blocks from the multiple task trace structures.
