\subsection tracing_tracing_options Tracing configuration Options
-These are the options accepted by the tracing system of SimGrid:
+To check which tracing options are available for your simulator, you
+can just run it with the option <b>--help-tracing</b>. These are the
+options accepted by the tracing system of SimGrid as of today, you
+can use them by running your simulator with the <b>--cfg=</b> switch:
\li <b>\c
tracing
</b>:
Safe switch. It activates (or deactivates) the tracing system.
No other tracing options take effect if this one is not activated.
+\verbatim
+--cfg=tracing:1
+\endverbatim
\li <b>\c
tracing/categorized
</b>:
It activates the categorized resource utilization tracing. It should
be enabled if tracing categories are used by this simulator.
+\verbatim
+--cfg=tracing/categorized:1
+\endverbatim
\li <b>\c
tracing/uncategorized
It activates the uncategorized resource utilization tracing. Use it if
this simulator do not use tracing categories and resource use have to be
traced.
+\verbatim
+--cfg=tracing/uncategorized:1
+\endverbatim
\li <b>\c
tracing/filename
tools. More information can be found in these webpages:
<a href="http://triva.gforge.inria.fr/">http://triva.gforge.inria.fr/</a>
<a href="http://paje.sourceforge.net/">http://paje.sourceforge.net/</a>
+\verbatim
+--cfg=tracing/filename:mytracefile.trace
+\endverbatim
+ If you do not provide this parameter, the trace file will be named simgrid.trace.
\li <b>\c
tracing/onelink_only
to re-create a "graph" of the platform and register it in the trace file.
This option let the user tell the tracing system to use only the routes
that are composed with just one link.
+\verbatim
+--cfg=tracing/onelink_only:1
+\endverbatim
\li <b>\c
tracing/smpi
interface and generates a trace that can be analyzed using Gantt-like
visualizations. Every MPI function (implemented by SMPI) is transformed in a
state, and point-to-point communications can be analyzed with arrows.
+\verbatim
+--cfg=tracing/smpi:1
+\endverbatim
\li <b>\c
tracing/smpi/group
</b>:
This option only has effect if this simulator is SMPI-based. The processes
are grouped by the hosts where they were executed.
+\verbatim
+--cfg=tracing/smpi/group:1
+\endverbatim
\li <b>\c
tracing/msg/task
</b>:
This option only has effect if this simulator is MSG-based. It traces the
behavior of all categorized MSG tasks, grouping them by hosts.
+\verbatim
+--cfg=tracing/msg/task:1
+\endverbatim
\li <b>\c
tracing/msg/process
This option only has effect if this simulator is MSG-based. It traces the
behavior of all categorized MSG processes, grouping them by hosts. This option
can be used to track process location if this simulator has process migration.
+\verbatim
+--cfg=tracing/msg/process:1
+\endverbatim
\li <b>\c
-triva/categorized:graph_categorized.plist
+triva/categorized
</b>:
This option generates a graph configuration file for Triva considering
categorized resource utilization.
+\verbatim
+--cfg=triva/categorized:graph_categorized.plist
+\endverbatim
\li <b>\c
-triva/uncategorized:graph_uncategorized.plist
+triva/uncategorized
</b>:
This option generates a graph configuration file for Triva considering
uncategorized resource utilization.
+\verbatim
+--cfg=triva/categorized:graph_uncategorized.plist
+\endverbatim
