+**Summary:** helper to debug cloud-init *internal* datastructures.
+
+**Description:** This module will enable for outputting various internal
+information that cloud-init sources provide to either a file or to the output
+console/log location that this cloud-init has been configured with when
+running.
+
+It can be configured with the following option structure::
+
+    debug:
+       verbose: (defaulting to true)
+       output: (location to write output, defaulting to console + log)
+
+.. note::
+
+    Log configurations are not output.
