+Devices emit netconf alarms and notifications in certain situations, which can demand
attention from Device Administration. The notifications are received as Netconf messages on an
active Netconf session.
Enabling WebSocket notifications in OpenDaylight requires a manual setup before starting the application.
The following steps can be followed to enable WebSocket notifications in OpenDaylight:
-1. Open the file `restconf8040.cfg`, at `etc/` folder inside your Karaf distribution.
-2. Locate the `use-sse` configuration parameter and change its value from `true` to `false`.
-3. Uncomment the `use-sse` parameter if it is commented out.
-4. Save the changes made to the `restconf8040.cfg` file.
-5. Restart OpenDaylight if it is already running.
+1. Open the file `org.opendaylight.restconf.nb.rfc8040.cfg`, at `etc/` folder inside your Karaf distribution. Or create in case it does not exist.
+2. Locate the `use-sse` configuration parameter and change its value from `true` to `false`. Or add ``use-sse=false`` as new line in case this parameter is not present.
+3. Save the changes made to the `org.opendaylight.restconf.nb.rfc8040.cfg` file.
+4. Restart OpenDaylight if it is already running.
Once these steps are completed, WebSocket notifications will be enabled in OpenDaylight,
and they can be used for receiving notifications instead of SSE.
Also, for testing purposes, there is simple Java application named
WebSocketClient. The application is placed in the
*/restconf/websocket-client* project. It accepts a WebSocket URI
-as and input parameter. After starting the utility (WebSocketClient

class directly in Eclipse/InteliJ Idea) received notifications should be
displayed in console.

+page data in real time. In this tutorial we will be using toaster as the
base.
When you call *make-toast* RPC, it sets *toasterStatus* to "down" to
reflect that the toaster is busy making toast. When it finishes,

+Restconf northbound configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Restconf-nb configuration works through OSGi Configuration Admin interface, in the
+``org.opendaylight.restconf.nb.rfc8040`` configuration PID. There are six tuneables you can
+set:
+
+* ``maximum-fragment-length``, which defaults to ``0``
+* ``heartbeat-interval``, which defaults to ``10000``
+* ``idle-timeout``, which defaults to ``30000``
+* ``ping-executor-name-prefix``, which defaults to ``ping-executor``
+* ``max-thread-count``, which defaults to ``1``
+* ``use-sse``, which defaults to ``true``
+* ``restconf``, which defaults to ``rests``
+
+*maximum-fragment-length* — Maximum web-socket fragment length in number of Unicode code units (characters)
+(exceeded message length leads to fragmentation of messages)
+
+*heartbeat-interval* — Interval in milliseconds between sending of ping control frames.
+
+*idle-timeout* — Maximum idle time of web-socket session before the session is closed (milliseconds).
+
+*ping-executor-name-prefix* — Name of thread group Ping Executor will be run with.
+
+*max-thread-count* — Number of threads Ping Executor will be run with.
+
+*use-sse* — In case of ``true`` access to notification streams will be via Server-Sent Events.
+Otherwise web-socket servlet will be initialized.
+
+*restconf* — The value of RFC8040 restconf URI template, pointing to the root resource. Must not end with '/'.
+
+In order to change these settings, you can either modify the corresponding configuration
+file, ``org.opendaylight.restconf.nb.rfc8040.cfg``, for example:
+
+::
+
+ maximum-fragment-length=0
+ heartbeat-interval=10000
+ idle-timeout=30000
+ ping-executor-name-prefix=ping-executor
+ max-thread-count=1
+ use-sse=true
+ restconf=rests
+

+::

+ opendaylight-user@root>config:edit org.opendaylight.restconf.nb.rfc8040
+ opendaylight-user@root>config:property-set maximum-fragment_length 0

+Once an entry is made on the config side of "allowed-devices", the Call-Home Server will
+populate a corresponding operational device that is the same as the config device but
has an additional status. By default, this status is *DISCONNECTED*. Once a device calls
home, this status will change to one of:

+Devices that are not on the allowlist might try to connect to the Call-Home Server. In
these cases, the server will keep a record by instantiating an operational device. There
will be no corresponding config device for these rogues. They can be identified readily
because their device id, rather than being user-supplied, will be of the form
The Call-Home Server listens for incoming TCP connections and assumes that the other side of
the connection is a device calling home via a NETCONF connection with SSH for

blueprint configuration file.
The device **must** initiate the connection and the server will not try to re-establish the

+If user would like to read only selected fields from a NETCONF device, it is possible to use

parameter into format that is accepted by NETCONF subtree filtering - filtering of data is done
on NETCONF server, not on NETCONF client side. This approach optimizes network traffic load,
because data in which user doesn't have interest, is not transferred over network.

+RESTCONF OpenAPI
+----------------
+
+Overview
+~~~~~~~~
+
+The OpenAPI provides full API for configurational data which can be edited (by POST, PUT, PATCH and DELETE).
+For operational data we only provide GET API. For the majority of requests you can see only config data in examples.
+That’s because we can show only one example per request. The exception when you can see operational data in an
+example is when data are representing an operational (config false) container with no config data in it.
+
+
+Using the OpenAPI Explorer through HTTP
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1. Install OpenApi into Karaf by installing karaf feature:
+
+::
+
+ $ feature:install odl-restconf-openapi
+
+2. Navigate to OpenAPI in your web browser which is available at URLs:
+
+- http://localhost:8181/openapi/explorer/index.html for general overview
+
+- http://localhost:8181/openapi/api/v3/single for JSON data
+
+.. note::
+
+ In the URL links for OpenAPI, change *localhost* to the IP/Host name of your actual server.
+
+3. Enter the username and password.
+ By default the credentials are *admin/admin*.
+
+4. Select any model to try out.
+
+5. Select any available request to try out.
+
+6. Click on the **Try it out** button.
+
+7. Provide any required parameters or edit request body.
+
+8. Click the **Execute** button.
+
+9. You can see responses to the given request.
+
+
+OpenAPI Explorer can also be used for connected device. How to connect a device can be found :ref:`here <netconf-connector>`.
+
+OpenAPI URLs in that case would look like this:
+
+- `http://localhost:8181/openapi/explorer/index.html?urls.primaryName=17830-sim-device resources - RestConf RFC 8040 <http://localhost:8181/openapi/explorer/index.html?urls.primaryName=17830-sim-device%20resources%20-%20RestConf%20RFC%208040>`_ for device overview
+
+- http://localhost:8181/openapi/api/v3/mounts/1 for JSON data
+
+- `http://localhost:8181/openapi/api/v3/mounts/1/toaster(2009-11-20) <http://localhost:8181/openapi/api/v3/mounts/1/toaster(2009-11-20)>`__ JSON data for given model
+
+.. note::
+
+ The URL links for OpenAPI are made for device with name *17830-sim-device* and model toaster
+ with *2009-11-20* revision and need to be changed accordingly to connected device.
