+Using remote-pdb
+----------------
+
+`remote-pdb`_ works while the process is under systemd control.
+
+Make sure you have remote-pdb installed::
+
+  sudo pip install remote-pdb
+
+Inject your breakpoint in the source, e.g.::
+
+  import remote_pdb; remote_pdb.set_trace()
+
+Restart the relevant service::
+
+  sudo systemctl restart devstack@n-api.service
+
+The remote-pdb code configures the telnet port when ``set_trace()`` is
+invoked.  Do whatever it takes to hit the instrumented code path, and
+inspect the logs for a message displaying the listening port::

+Telnet to that port to enter the pdb session::
