+Logging & Diagnostic Information
+---------------------------------
+
+In the Amsterdam release, the logs are kept inside the docekr containers, which means that you can get the log information only when the docker is still running. 
+
+Where to Access Information
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Assume that the name of a running docker is *holmes-rule-mgmt*, the way to get the log is to run the command ``docker logs ${docker-name}`` in the command window:
+
+``sudo docker logs holmes-rule-mgmt``
+
+Then the logs will be displayed in the command window.
+
