Abstract
Inserting key frames during indexing of a trace for responsive trace replay. A method includes identifying responsiveness goal(s) for trace replay, including identifying a target trace section replay time. A portion of execution of executable entit(ies) is replayed based on first trace data stream(s). While replaying execution of the executable entit(ies), and based on the identified target trace section replay time, points of interest in execution of the executable entit(ies) are identified. Second trace data stream(s) are recorded, which includes inserting a key frame into the second trace data stream(s) at, or near, each of the identified points of interest, to create a plurality of trace sections. Each key frame enables replay of at least one of the executable entities beginning at the key frame.
