Abstract: Techniques and mechanisms to determine a selective buffering of various trace data to different respective buffers. In an embodiment, sort rules indicate trace data attributes that are each to correspond to a different respective buffer. The sort rules are enforced during a runtime session to concurrently sort different items of trace data, based on associated trace data attributes, for storage each to a corresponding buffer. In another embodiment, trigger rules are enforced during the runtime session to selectively debuffer only some trace data based on trigger conditions variously corresponding to different respective trace data types. In still another embodiment, enforcement of sort rules and/or trigger rules is modified during the runtime session to enable dynamic changes to the buffering or debuffering of trace data.
