Analyze Discontinuous Trace

Trace is organized chronologically by nature. However, hard reset of the system might distort the timestamp order. The correct chronological order of the trace is indicated by the Interval (Intvl) prefix.

The idea is simple: each time a timestamp is reset, the subsequent messages are grouped in a detached section time-wise. This section is identified as an “Interval” and labeled with an incremental number starting from zero. Therefore, the Interval can be seen as an extension of the timestamps and an integral part of the System Trace.

Visual cues:

• When a trace session contains several Intervals, timestamps are prefixed with the Interval number.

• The Message Distribution view and the Timeline Viewer show Intervals in the chronological order.

• The Message Distribution view displays the duration of each Interval.

• The Time Difference view shows the time distance between selected timestamps. As the time distance between Intervals is undetermined, you can only measure time difference between timestamps belonging to one Interval.
