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 <http://docker.io/>`__
2. Pull the latest container from onap nexus
.. code-block:: bash
sudo docker login -u docker -p docker
`nexus.onap.org <http://nexus.onap.org/>`__:10001
sudo docker pull
`nexus.onap.org <http://nexus.onap.org/>`__:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:1.1
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 <http://nexus.onap.org/>`__:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:1.1
.. 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 <http://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": "2.0.0",
"scope": "user"
},
"config": {

"tcaVESAlertsTableTTLSeconds": 1728000.0,
"thresholdCalculatorFlowletInstances": 2.0,
"tcaSubscriberOutputStreamName": "TCASubscriberOutputStream"
}
}
6. Create TCA app preference file under ~ubuntu as below
.. code-block:: json

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

rm -f /home/ubuntu/$TCA_JAR
cd /home/ubuntu/
wget https://nexus.onap.org/service/local/repositories/staging/content/org/onap/dcaegen2/analytics/tca/dcae-analytics-cdap-tca/2.0.0/$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

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
