+Yardstick User Interface
+========================
+
+This interface provides a user to view the test result
+in table format and also values pinned on to a graph.
+
+
+Command
+-------
+::
+
+ yardstick report generate <task-ID> <testcase-filename>
+
+
+Description
+-----------
+
+1. When the command is triggered using the task-id and the testcase
+name provided the respective values are retrieved from the
+database (influxdb in this particular case).
+
+2. The values are then formatted and then provided to the html
+template framed with complete html body using Django Framework.
+
+3. Then the whole template is written into a html file.
+
+The graph is framed with Timestamp on x-axis and output values
+(differ from testcase to testcase) on y-axis with the help of
+"Highcharts".

++--------------+--------------------------------------------------------------+
+|step 2 | Yardstick is connected with the server VM by using ssh. |
+| | 'ping_benchmark' bash script is copyied from Jump Host to |

++--------------+--------------------------------------------------------------+
+|step 3 | Ping is invoked. Ping packets are sent from server VM to |
