Tracing cascaded data is similar
to trace stream data. Cascade data analysis in the trace view allows you to cross probe
from a specific input/output cascade connection in the Graph view to the appropriate position in the
event trace view. You can trace cascade input data as it is being received during the
kernel execution. To perform data analysis on a cascade interface, use the following
steps.
- The following image shows a kernel port that has been selected in the
Graph view. The
selected port is highlighted both in the Graph view and in the ports table at bottom of the
window.
- Switch to the Trace
to view the events and detailed event timing.
- View the data associated with the selected input port.
- Put the cursor in the timeline of the trace view. In the events table to
view data in
DATAcolumn.
Using these steps, you can inspect I/O data
for the required cascade connections to ensure the correctness of the I/O data to and
from a kernel.
