+NFVbench Fluentd Integration
+============================================
+
+NFVbench has an optional fluentd integration to save logs and results.
+
+Configuring Fluentd to receive NFVbench logs and results
+--------------------------------------------------------
+
+The following configurations should be added to Fluentd configuration file to enable logs or results.
+
+To receive logs, and forward to a storage server:
+
+In the example below nfvbench is the tag name for logs (which should be matched with logging_tag
+under NFVbench configuration), and storage backend is elasticsearch which is
+running at localhost:9200.
+
+
+.. code-block:: bash
+    <match nfvbench.**>
+    @type copy
+    <store>
+        @type elasticsearch
+        host localhost
+        port 9200
+        logstash_format true
+        logstash_prefix nfvbench
+        utc_index false
+        flush_interval 15s
+    </store>
+    </match>
+
+To receive results, and forward to a storage server:
+
+In the example below resultnfvbench is the tag name for results (which should be matched with result_tag
+under NFVbench configuration), and storage backend is elasticsearch which is
+running at localhost:9200.
+
+.. code-block:: bash
+    <match resultnfvbench.**>
+    @type copy
+    <store>
+        @type elasticsearch
+        host localhost
+        port 9200
+        logstash_format true
+        logstash_prefix resultnfvbench
+        utc_index false
+        flush_interval 15s
+    </store>
+    </match>
+
+Configuring NFVbench to connect Fluentd
+---------------------------------------
+
+To configure NFVbench to connect Fluentd, fill following configuration parameters in the
+configuration file
+
++------------------------------------------------------+------------------------------------------------------+
+| Configuration                                        | Description                                          |
++======================================================+======================================================+
+| logging_tag                                          | Tag for NFVbench logs, it should be the same tag     |
+|                                                      | defined in Fluentd configuration                     |
++------------------------------------------------------+------------------------------------------------------+
+| result_tag                                           | Tag for NFVbench results, it should be the same tag  |
+|                                                      | defined in Fluentd configuration                     |
++------------------------------------------------------+------------------------------------------------------+
+| ip                                                   | ip address of Fluentd server                         |
++------------------------------------------------------+------------------------------------------------------+
+| port                                                 | port number of Fluentd serverd                       |
++------------------------------------------------------+------------------------------------------------------+
+
+An example of configuration for Fluentd working at 127.0.0.1:24224 and tags for logging is nfvbench
+and result is resultnfvbench
+
+.. code-block:: bash
+    fluentd:
+        # by default (logging_tag is empty) nfvbench log messages are not sent to fluentd
+        # to enable logging to fluents, specify a valid fluentd tag name to be used for the
+        # log records
+        logging_tag: nfvbench
+
+        # by default (result_tag is empty) nfvbench results are not sent to fluentd
+        # to enable sending nfvbench results to fluentd, specify a valid fluentd tag name
+        # to be used for the results records, which is different than logging_tag
+        result_tag: resultnfvbench
+
+        # IP address of the server, defaults to loopback
+        ip: 127.0.0.1
+
+        # port # to use, by default, use the default fluentd forward port
+        port: 24224
+
+Example of logs and results
+---------------------------
+
+An example of log obtained from fluentd by elasticsearch:
+
+.. code-block:: bash
+
+    {
+      "_index": "nfvbench-2017.10.17",
+      "_type": "fluentd",
+      "_id": "AV8rhnCjTgGF_dX8DiKK",
+      "_version": 1,
+      "_score": 3,
+      "_source": {
+        "loglevel": "INFO",
+        "message": "Service chain 'PVP' run completed.",
+        "@timestamp": "2017-10-17T18:09:09.516897+0000",
+        "runlogdate": "2017-10-17T18:08:51.851253+0000"
+      },
+      "fields": {
+        "@timestamp": [
+          1508263749516
+        ]
+      }
+    }
+
+
+
+For each packet size and rate a result record is sent. Users can label those results by passing
+--user-label parameter to NFVbench run
+
+.. code-block::bash
+    nfvbench --rate 1% --user-label nfvbench-label
+
+And the results of this command obtained from fluentd by elasticsearch:
+
+.. code-block:: bash
+
+    {
+      "_index": "resultnfvbench-2017.10.17",
