+T-Rex JSON Template
+===================
+
+Whenever T-Rex is publishing live data, it uses JSON notation to describe the data-object.
+
+Each client may parse it diffrently, however this page will describe the values meaning when published by T-Rex server.
+
+
+Main Fields
+-----------
+
+Each T-Rex server-published JSON object contains data divided to main fields under which the actual data lays.
+
+These main fields are:
+
++-----------------------------+----------------------------------------------------+---------------------------+
+| Main field | Contains | Comments |
++=============================+====================================================+===========================+
+| :ref:`trex-global-field` | Must-have data on T-Rex run, | |
+| | mainly regarding Tx/Rx and packet drops | |
++-----------------------------+----------------------------------------------------+---------------------------+
+| :ref:`tx-gen-field` | Data indicate the quality of the transmit process. | |
+| | In case histogram is zero it means that all packets| |
+| | were injected in the right time. | |
++-----------------------------+----------------------------------------------------+---------------------------+
+| :ref:`trex-latecny-field` | Latency reports, containing latency data on | - Generated when latency |
+| | generated data and on response traffic | test is enabled (``l`` |
+| | | param) |
+| | | - *typo* on field key: |
++-----------------------------+----------------------------------------------------+ will be fixed on next |
+| :ref:`trex-latecny-v2-field`| Extended latency information | release |
++-----------------------------+----------------------------------------------------+---------------------------+
+
+
+Each of these fields contains keys for field general data (such as its name) and its actual data, which is always stored under the **"data"** key.
+
+For example, in order to access some trex-global data, the access path would look like::
+
+ AllData -> trex-global -> data -> desired_info
+
+
