With the PID tracker, it is possible, for example, to record all system
calls called by a given process:
+[role="term"]
-------------------------------------------
lttng enable-event --kernel --all --syscall
lttng track --kernel --pid=2345
Command:
+[role="term"]
-----------------------------------
lttng track --userspace --pid=3,6,7
-----------------------------------
Command:
+[role="term"]
---------------------------------
lttng untrack --userspace --pid=7
---------------------------------
Command:
+[role="term"]
---------------------------------
lttng track --userspace --pid=1,5
---------------------------------
