Telemetry
^^^^^^^^^
The username and password for the Telemetry commands are in *${POLCIY_HOME}/config/policy-engine.properties*.

Injecting messages:
-------------------

To inject messages use the following command.  The injected message will look as if it came in from the specified topic and will be processed accordingly.

Use the command:

    .. code-block:: bash

        http -a <userName>:<password> PUT :9696/policy/pdp/engine/topics/sources/ueb/<topic>/events @<onsetFile> Content-Type:"text/plain"

Alternatively, this command could be used:

    .. code-block:: bash

        curl --silent --user <userName>:<password> -X PUT --header "Content-Type: text/plain" –data @<onsetFile> http://localhost:9696/policy/pdp/engine/topics/sources/ueb/<topic>/events

The topic beeing used is *unauthenticated.DCAE_CL_OUTPUT*, which is subject to change.  The onset file is a file that contains the data to inject as the onset.  The data contained depends on the use case. This is an example for VoLTE:

    .. code-block:: json
       :caption: VoLTE_Sample_Onset

        {
            "closedLoopControlName": "ControlLoop-VOLTE-2179b738-fd36-4843-a71a-a8c24c70c55b",

            "closedLoopEventClient": "DCAE.HolmesInstance",
            "closedLoopEventStatus": "ONSET",
            "requestID": "97964e10-686e-4790-8c45-bdfa61df770f",
            "target_type": "VM",
            "target": "vserver.vserver-name",
            "AAI": {
                "vserver.is-closed-loop-disabled": "false",
                "vserver.vserver-name": "dfw1lb01lb01",
                "service-instance.service-instance-id" : "vserver-name-16102016-aai3255-data-11-1",
                "generic-vnf.vnf-id" : "vnf-id-16102016-aai3255-data-11-1",
                "generic-vnf.vnf-name" : "vnf-name-16102016-aai3255-data-11-1"
            },
            "from": "DCAE",
            "version": "1.0.2"
        }

Getting Information 
-------------------

To get the name of the controller(s) active, use:

    .. code-block:: bash

        curl --silent --user <username>:<password> -X GET http://localhost:9696/policy/pdp/engine/controllers | python -m json.tool

To check the facts currently in memory, use the following command.  There should be 1 each of org.onap.policy.controlloop.PapParams and org.onap.policy.controlloop.Params per policy pushed.

    .. code-block:: bash

        curl --silent --user <username>:<password> -X GET http://localhost:9696/policy/pdp/engine/controllers/<controllerName>/drools/facts/<artifactId> | python -m json.tool

To get additional information about the controller, use:

    .. code-block:: bash

        curl --silent --user <username>:<password> -X GET http://localhost:9696/policy/pdp/engine/controllers/<controllerName> | python -m json.tool


Simulators
^^^^^^^^^^

Currently, there are 4 supported simulators: A&AI, SO, vFC, and guard.  When they are up, they are accessed via localhost on the following ports: A&AI – 6666, SO – 6667, vFC – 6668, and guard – 6669.  They all respond with hard-coded values representing their various success messages except for with certain inputs.  For the A&AI simulator, if the value being queried with a “GET” query is “getFail” the simulator returns an exception message, if the value being queried in a “GET” query is “disableClosedLoop” the simulator returns a response with the value of “is-closed-loop-disabled” set to true, and if the value being queried in a named query is “error” the response from the simulator is A&AI’s failure message.  The other simulator that can return multiple response is the guard simulator, and that returns a deny response if the closed loop control name passed in is “denyGuard” 

Using the Simulators
--------------------

To check the status of the simulators, run the command: "*features status*".  If the feature controlloop-utils is enabled, the simulators are being used, otherwise, they are not.

**Turning on the simulators**

    - First, make sure the controller is off by running the command “*policy stop*”. 
    - Then turn the feature on with the command “*features enable controlloop-utils*”.  
    - Finally restart the controller by running “*policy start*”.  
    - Run “*features status*” again and the *feature controlloop-utils* will be **enabled**.

**Turning the simulators off**

    - First, make sure the controller is off by running the command “*policy stop*”. 
    - Then turn the feature off with the command “*features disable controlloop-utils*”.
    - Finally restart the controller by running “*policy start*”.  
    - Run “*features status*” again and the *feature controlloop-utils* will be **disabled**.

**For Junits**

    For Junits, the package *org.onap.policy.simulators* is neeeded.  In the Util class, there are four methods to start the four different simulators: *buildAaiSim()*, *buildSoSim()*, *buildVfcSim()*, and *buildGuardSim()*.  Once the method is called, the simulator should be up and waiting to respond to requests.  To bring down the simulators, call *HttpServletServer.factory.destroy()*.
