Overlapping Data

Overlapping data is data within the trace from different sources within the same link that have
overlapping timestamps. Each link (either a wide link or a port-pair) has its own set of start and
stop timestamps with the trace. The
is selected TraceView shows only the overlapped data. When it is unselected, TraceView shows
the whole trace. When showing all trace data by toggling the
you may display data that does not contain the corresponding response data from the other side of
the link. For most types of analysis, this data from only one side of the link will not be very useful.
When the
data, is updated to correspond to current time extents. Overlapped time is calculated per link. If a
partial link is available (because a subset of ports are opened from chassis, or a single .trc file is
opened) only available ports are used to determine overlapped time extents.
By showing overlapping data, you are reducing the amount of data displayed for the trace.
Showing overlapping data only can narrow your view to critical sections when viewing large
traces. If you select to show overlapping data only, the yellow extent bars in the histogram will
move if this operation eliminates some of the data in the trace from the display. If you select to
show overlapping data, the yellow tickers are shown at lowest of the start times for all links and
highest of the end times for all the links. If you select to show the entire trace, the yellow tickers
are shown at the beginning and end of the trace. Ticker marker positions are not altered based on
port selection. You can select custom time extents by sliding yellow ticker markers. When
