+
+Some scenarios that might help you decide which tracing options
+you should use to analyze your simulator.
+
+\li I want to trace the resource utilization of all hosts
+and links of the platform, and my simulator <b>does not</b> use
+the tracing API. For that, you can run a uncategorized trace
+with the following parameters (it will work with <b>any</b> Simgrid
+simulator):
+\verbatim
+./your_simulator \
+ --cfg=tracing:1 \
+ --cfg=tracing/uncategorized:1 \
+ --cfg=tracing/filename:mytracefile.trace \
+ --cfg=triva/uncategorized:uncat.plist
+\endverbatim
+
+\li I want to trace only a subset of my MSG (or SimDAG) tasks.
+For that, you will need to create tracing categories using the
+<b>TRACE_category (...)</b> function (as explained above),
+and then classify your tasks to a previously declared category
+using the <b>TRACE_msg_set_task_category (...)</b>
+(or <b>TRACE_sd_set_task_category (...)</b> for SimDAG tasks). After
+recompiling, run your simulator with the following parameters:
+\verbatim
+./your_simulator \
+ --cfg=tracing:1 \
+ --cfg=tracing/categorized:1 \
+ --cfg=tracing/filename:mytracefile.trace \
+ --cfg=triva/categorized:cat.plist
+\endverbatim
