The below steps covers manual setup of DCAE VM’s and DCAE service components.
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
sudo apt-get update
sudo apt install docker.io
2) Pull the latest container from onap nexus
sudo docker login -u docker -p docker nexus3.onap.org:10001
sudo docker pull nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:v1.1.0
3) Start the VESCollector with below command
sudo docker run -d --name vescollector -p 8080:8080/tcp -p 8443:8443/tcp -P -e DMAAPHOST='<dmaap IP>' nexus3.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
curl -i -X POST -d @<sampleves> --header "Content-Type: application/json" http://localhost:8080/eventListener/v5 -k
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).
3. 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
To address windriver server in-stability, the below init.sh script was used to start the container on VM restart.
#!/bin/sh sudo docker ps | grep "vescollector" if [ $? -ne 0 ]; then sudo docker login -u docker -p docker nexus3.onap.org:10001 sudo docker pull nexus3.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' nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:v1.1.0 else echo "Collector process running - $(date)" >> /home/ubuntu/startuplog fi |
This script was invoked via VM init script (rc.d).
ln -s /home/ubuntu/init.sh /etc/init.d/init.sh
sudo update-rc.d init.sh start 2
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
sudo apt-get update
sudo apt install docker.io
2) Pull CDAP SDK container
sudo docker pull caskdata/cdap-standalone:4.1.2
3) Deploy and run the CDAP container
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
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
{
"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 - "tca_app_preferences.json" under ~ubuntu as below
{
"publisherContentType" : "application/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**
6 a) To enable AAI Enrichment in TCA for CL event, following updates should be done to TCA app preference file before proceeding
"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
#!/bin/sh TCA_JAR=dcae-analytics-cdap-tca-2.0.0.jar rm -f /home/ubuntu/$TCA_JAR cd /home/ubuntu/ wget https://nexus3.onap.org/service/local/repositories/releases/content/org/onap/dcaegen2/analytics/tca/dcae-analytics-cdap-tca/2.0.0/$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: $TCA_JAR not found in nexus" exit 1 fi # stop programs curl -X POST http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/workers/TCADMaaPMRPublisherWorker/stop curl -X POST http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/workers/TCADMaaPMRSubscriberWorker/stop curl -X POST http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/flows/TCAVESCollectorFlow/stop # delete application curl -X DELETE http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca # delete artifact curl -X DELETE http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/artifacts/dcae-analytics-cdap-tca/versions/2.0.1 # load artifact curl -X POST --data-binary @/home/ubuntu/$TCA_JAR http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/artifacts/dcae-analytics-cdap-tca # create app curl -X PUT -d @/home/ubuntu/tca_app_config.json http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca # load preferences curl -X PUT -d @/home/ubuntu/tca_app_preferences.json http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/preferences # start programs 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 echo # get status of programs curl http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/workers/TCADMaaPMRPublisherWorker/status curl http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/workers/TCADMaaPMRSubscriberWorker/status curl http://localhost:11015/v3/namespaces/cdap_tca_hi_lo/apps/dcae-tca/flows/TCAVESCollectorFlow/status echo |
Note: Attached the script also for reference : reload-tca.sh
8) Verify TCA application and logs via CDAP GUI processes
http://<hostname/ip>:11011/oldcdap/ns/cdap_tca_hi_lo/apps/dcae-tca/overview/programs
The overall flow can be checked here
http://<hostname/ip>:11011/oldcdap/ns/cdap_tca_hi_lo/apps/dcae-tca/programs/flows/TCAVESCollectorFlow/runs
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.
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).
