It is typically set up under the */opt/app/policy* directory but can be changed during installation. All PDP-D software runs with non-root privileges as *policy* is a regular user account. + +Once within the drools container, the running status can be observed by using the *policy* command: + + .. code-block:: bash + + policy [--debug] status|start|stop + +The running status of the PDP-D can be observed with *policy status* + + .. code-block:: bash + + policy@drools:~$ policy status [drools-pdp-controllers] L []: Policy Management (pid 1500) is running 1 cron jobs installed. + + +Prerequisites for the vDNS flow +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +In order to trigger the vDNS flow we will need to inject an ONSET message via curl command. We're going to create a temporary *util* directory to store a file that contains the vDNS ONSET message. + +Navigate to */tmp* and create directory *util*. *util* is just a temporary folder we've created to use as our 'workspace'. + + .. code-block:: bash + + cd /tmp + mkdir util + + +Next, we're going to create a file named *dcae.vdns.onset.json* and edit it to paste the vDNS ONSET message contents. + + .. code-block:: bash + + touch dcae.vdns.onset.json + vi dcae.vdns.onset.json + +Here are the contents of the vDNS ONSET message. Copy/paste this into dcae.vdns.onset.json: + + .. code-block:: json + + { + "closedLoopControlName": "ControlLoop-vDNS-6f37f56d-a87d-4b85-b6a9-cc953cf779b3", + "closedLoopAlarmStart": 1484677482204798, + "closedLoopEventClient": "DCAE_INSTANCE_ID.dcae-tca", + "closedLoopEventStatus": "ONSET", + "requestID": "e4f95e0c-a013-4530-8e59-c5c5f9e539b6", + "target_type": "VNF", + "target": "vserver.vserver-name", + "AAI": { + "vserver.is-closed-loop-disabled": "false", + "vserver.prov-status": "ACTIVE", + "vserver.vserver-name": "dfw1lb01lb01" + }, + "from": "DCAE", + "version": "1.0.2" + } + + + +Enabling the AAI and SO Simulators +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Enabling the *controlloop-utils* feature will enable the simulators. To do this, simply stop the drools pdp, enable the feature, and restart the drools pdp like so: + + .. code-block:: bash + + policy stop + features enable controlloop-utils + policy start + +Now, in */opt/app/policy/config/* directory, you should see a new properties file named *simulators.properties.environment*. In here you will find the credentials for the AAI and SO simulators. + +Injecting an ONSET to trigger the vDNS Flow +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +We are now ready to inject an ONSET message to trigger the vDNS flow. Simply navigate back to the directory *dcae.vdns.onset.json* file is saved (i.e. cd /tmp/util) and run this curl command: + + .. code-block:: bash + + http --verify=no --default-scheme=https -a @1b3rt:31nst31n PUT :9696/policy/pdp/engine/topics/sources/ueb/unauthenticated.DCAE_CL_OUTPUT/events @dcae.vdns.onset.json Content-Type:"text/plain" + +You should see some output similar to this: + + .. image:: tutorial_vDNS_1.png + +You can view the logs to see the network activity or find any errors that may have occurred. Logs are located in */opt/app/policy/logs*. + +Reading the logs +^^^^^^^^^^^^^^^^ + +Once you've injected the onset message, this should appear in the network.log: + + .. image:: tutorial_vDNS_2.png + + +End of Document + +..
