Command Log File Reports
As with trace files collected with SASTracer, command log files generated by SASTracker
have access to reporting capabilities within the SASSuite program.
One of the more useful reports available for SASTracker Command Log Files is the "Bus
Utilization" report, which in the case of SASTracker files will show the following:
•
The number of pending commands at all times during the period that the
Command Log File was recording. This display is useful to determine the
outstanding commands that existed at any point in time, and to determine
times at which the number of pending commands was larger than usual for
the system.
•
The command duration for all completed commands contained within the
command log file, shown against the time they occurred within the recorded
trace. This display highlights commands which were taking unusually long
times to complete, and by having this data aligned with the pending
command data mentioned above, the user can determine whether long
command completion times are related to the number of pending commands,
or due to some other effect.
To display the Bus Utilization report, select the Bus Utilization menu selection in the
Report menu, or click the Bus Utilization button
in the Analysis toolbar.
The following graphs are displayed in the bottom half of the screen:
The graph display can be customized to focus on areas of particular interest using the
tools provided in the icons at the top of the graph. By double-clicking at any point within
the graph area, the Command Log File display in the top half of the screen will jump to
that section of the file. For more information on manipulating this display, see “Bus
Utilization” on page 176.
