+
+As shown in Framework_, there are two ways to store Storperf test results
+into community's InfluxDB:
+
+1. Yardstick asks Storperf to run the test case. After the test case is
+   completed, Yardstick reads test results via ReST API from Storperf and
+   posts test data to the influxDB.
+
+2. Additionally, Storperf can run tests by itself and post the test result
+   directly to the InfluxDB. The method for posting data directly to influxDB
+   will be supported in the future.
+
+Our plan is to support rest-api in D release so that other testing projects can
+call the rest-api to use yardstick dispatcher service to push data to yardstick's
+influxdb database.
+
+For now, influxdb only support line protocol, and the json protocol is deprecated.
+
+Take ping test case for example, the raw_result is json format like this:
+::
+
+    "benchmark": {
+        "timestamp": 1470315409.868095,
+        "errors": "",
+        "data": {
+          "rtt": {
+          "ares": 1.125
+          }
+        },
+      "sequence": 1
+      },
+    "runner_id": 2625
+  }
+
+With the help of "influxdb_line_protocol", the json is transform to like below as a line string:
+::
+
+  'ping,deploy_scenario=unknown,host=athena.demo,installer=unknown,pod_name=unknown,
+    runner_id=2625,scenarios=Ping,target=ares.demo,task_id=77755f38-1f6a-4667-a7f3-
+      301c99963656,version=unknown rtt.ares=1.125 1470315409868094976'
+
+So, for data output of json format, you just need to transform json into line format and call
+influxdb api to post the data into the database. All this function has been implemented in Influxdb_.
+If you need support on this, please contact Mingjiang_.
+::
+
+  curl -i -XPOST 'http://104.197.68.199:8086/write?db=yardstick' --
+    data-binary 'ping,deploy_scenario=unknown,host=athena.demo,installer=unknown, ...'
+
+Grafana will be used for visualizing the collected test data, which is shown in Visual_. Grafana
+can be accessed by Login_.
