DCAE Installation
=================

The below steps covers manual setup of DCAE VM’s and DCAE service
components.

VESCollector
------------

 

DCAE VES Collector can be configured on VM with ubuntu-16.04 image
(m1.small should suffice if this is only service) and 20Gb cinder
storage

1. Install docker

.. code-block:: bash

   sudo apt-get update
   sudo apt install docker.io

2. Pull the latest container from onap nexus

.. code-block:: bash

   sudo docker login -u docker -p docker nexus.onap.org:10001

   sudo docker pull nexus.onap.org:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:v1.1.0

3. Start the VESCollector with below command

.. code-block:: bash

   sudo docker run -d --name vescollector -p 8080:8080/tcp -p
   8443:8443/tcp -P -e DMAAPHOST='<dmaap IP>'
   nexus.onap.org:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:v1.1.0

.. Note:  Change the dmaaphost to required DMAAP ip. To change the
   dmaap information for a running container,  stop the active
   container and rerun above command changing the dmaap IP.

4. Verification

i.  Check logs under container /opt/app/VESCollector/logs/collector.log
        for errors

ii. If no active feed, you can simulate an event into collector via curl

.. code-block:: bash

   curl -i  -X POST -d @<sampleves> --header "Content-Type:application/json" -k http://localhost:8080/eventListener/v5

.. Note: If DMAAPHOST provided is invalid, you will see exception
   around publish on the collector.logs (collector queues and attempts
   to resend the event hence exceptions reported will be periodic). 

i. Below two topic configuration are pre-set into this container.  When
       valid DMAAP instance ip was provided and VES events are received,
       the collector will post to below topics.

    Fault -
     http://<dmaaphost>:3904/events/unauthenticated.SEC\_FAULT\_OUTPUT

    Measurement
    -http://<dmaaphost>:3904/events/unauthenticated.SEC\_MEASUREMENT\_OUTPUT

VM Init
~~~~~~~

To address windriver server in-stability, the below **init.sh** script
was used to start the container on VM restart.  

.. code-block:: bash

   #!/bin/sh
   sudo docker ps | grep “vescollector”
   if [ $? -ne 0 ]; then
          sudo docker login -u docker -p docker nexus.onap.org:10001
          sudo docker pull nexus.onap.org:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:1.1
          sudo docker rm -f vescollector
          echo “Collector process not running - $(date)” >> /home/ubuntu/startuplog
          sudo docker run -d –name vescollector -p 8080:8080/tcp -p 8443:8443/tcp -P -e DMAAPHOST=‘10.12.25.96’ nexus.onap.org:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:1.1
   else
          echo “Collector process running - $(date)” >> /home/ubuntu/startuplog
   fi


This script was invoked via VM init script (rc.d).

.. code-block:: bash

   ln -s /home/ubuntu/init.sh /etc/init.d/init.sh
   sudo  update-rc.d init.sh start 2

 

ThresholdCrossingAnalysis (TCA/CDAP)
------------------------------------

The platform deploys CDAP as cluster and instantiates TCA. For the
manual setup, we will leverage the CDAP SDK docker container to deploy
TCA instances.  To setup TCA, choose VM with ubuntu-16.04 image,
m1.medium size and 50gb cinder volumes.

1. Install docker

.. code-block:: bash

   sudo apt-get update
   sudo apt install docker.io

2. Pull CDAP SDK container

.. code-block:: bash

   sudo docker pull caskdata/cdap-standalone:4.1.2

3. Deploy and run the CDAP container

.. code-block:: bash

   sudo docker run -d --name cdap-sdk-2 -p 11011:11011 -p 11015:11015
   caskdata/cdap-standalone:4.1.2

4. Create Namespace on CDAP application

.. code-block:: bash

   curl -X PUT http://localhost:11015/v3/namespaces/cdap_tca_hi_lo

5. Create TCA app config file - "tca\_app\_config.json" under ~ubuntu as below

.. code-block:: json

 {
   "artifact": {
     "name": "dcae-analytics-cdap-tca",
     "version": "2.0.1",
     "scope": "user"
   },

   "config": {
     "appName": "dcae-tca",
     "appDescription": "DCAE Analytics Threshold Crossing Alert Application",
     "tcaVESMessageStatusTableName": "TCAVESMessageStatusTable",
     "tcaVESMessageStatusTableTTLSeconds": 86400.0,
     "tcaAlertsAbatementTableName": "TCAAlertsAbatementTable",
     "tcaAlertsAbatementTableTTLSeconds": 1728000.0,
     "tcaVESAlertsTableName": "TCAVESAlertsTable",
     "tcaVESAlertsTableTTLSeconds": 1728000.0,
     "thresholdCalculatorFlowletInstances": 2.0,
     "tcaSubscriberOutputStreamName": "TCASubscriberOutputStream"
   }
 }


6. Create TCA app preference file under ~ubuntu as below

.. code-block:: json

  "publisherHostName" : "10.12.25.96",
  "publisherHostPort" : "3904",

}"
 }


.. Note: Dmaap configuration are specified on this file on
   publisherHostName and subscriberHostName. To be changed as
   required\*\*

6a. To enable AAI Enrichment in TCA for CL event, following updates should be done to TCA app preference file before proceeding

.. code-block:: json

          "enableAAIEnrichment" :  true
          "aaiEnrichmentHost" :  <should be set to aai1_ip_addr>
          "aaiEnrichmentIgnoreSSLCertificateErrors" : true



7. Copy below script to CDAP server (this gets latest image from nexus and deploys TCA application) and execute it

.. code-block:: bash

 #!/bin/sh
 TCA_JAR=dcae-analytics-cdap-tca-2.0.1.jar
 rm -f /home/ubuntu/$TCA_JAR
 cd /home/ubuntu/
 wget https://nexus.onap.org/service/local/repositories/releases/content/org/onap/dcaegen2/analytics/tca/dcae-analytics-cdap-tca/2.0.1/$TCA_JAR
 if [ $? -eq 0 ]; then
        if [ -f /home/ubuntu/$TCA_JAR ]; then
                echo “Restarting TCA CDAP application using $TCA_JAR artifact”
        else
                echo “ERROR: $TCA_JAR missing”
                exit 1
        fi
 else
        echo “ERROR: $TCA_JAR not found in nexus”
        exit 1
 fi

8. Verify TCA application and logs via CDAP GUI processes

    The overall flow can be checked here

TCA Configuration Change
~~~~~~~~~~~~~~~~~~~~~~~~

Typical configuration changes include changing DMAAP host and/or Policy configuration. If necessary, modify the file on step #6 and run the script noted as step #7 to redeploy TCA with updated configuration.

VM Init
~~~~~~~

To address windriver server in-stability, the below **init.sh** script
was used to restart the container on VM restart.  This script was
invoked via VM init script (rc.d).

.. code-block:: bash

   #!/bin/sh
   #docker run -d –name cdap-sdk -p 11011:11011 -p 11015:11015 caskdata/cdap-standalone:4.1.2
   sudo docker restart cdap-sdk-2
   sleep 30
   # start program
   curl -X POST http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/workers/TCADMaaPMRPublisherWorker/start
   curl -X POST http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/workers/TCADMaaPMRSubscriberWorker/start
   curl -X POST http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/flows/TCAVESCollectorFlow/start


This script was invoked via VM init script (rc.d).

.. code-block:: bash

   ln -s /home/ubuntu/init.sh /etc/init.d/init.sh
   sudo  update-rc.d init.sh start 2
