+Viewing StorPerf Logs
+=====================
+
+Logs are an integral part of any application as they help debugging the application. The user just
+needs to issue an HTTP request. To view the entire logs
+
+.. code-block:: bash
+
+ curl -X GET --header 'Accept: application/json' http://StorPerf:5000/api/v1.0/logs?lines=all
+
+Alternatively, one can also view a certain amount of lines by specifying the number in the
+request. If no lines are specified, then last 35 lines are returned
+
+.. code-block:: bash
+
+ curl -X GET --header 'Accept: application/json' http://StorPerf:5000/api/v1.0/logs?lines=12 \ No newline at end of file
