+Architecture of the Tracing and Profiling Tools
+===============================================
+
+It may seem surprising to see a section covering an 'overall
+architecture' for what seems to be a random collection of tracing tools
+that together make up the Linux tracing and profiling space. The fact
+is, however, that in recent years this seemingly disparate set of tools
+has started to converge on a 'core' set of underlying mechanisms:
+
+-  static tracepoints
+-  dynamic tracepoints
+
+   -  kprobes
+   -  uprobes
+
+-  the perf_events subsystem
+-  debugfs
+
+.. admonition:: Tying it Together
+
+   Rather than enumerating here how each tool makes use of these common
+   mechanisms, textboxes like this will make note of the specific usages
+   in each tool as they come up in the course of the text.
