DCAE mS Deployment (Standalone instantiation)





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

  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

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

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

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

VM Init

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

init.sh
#!/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



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

 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

tca_app_config.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 - "tca_app_preferences.json" under ~ubuntu as below

tca_app_preferences.json
{   "publisherContentType" : "application/json",   "publisherHostName" : "10.12.25.96",   "publisherHostPort" : "3904",   "publisherMaxBatchSize" : "1",   "publisherMaxRecoveryQueueSize" : "100000",   "publisherPollingInterval" : "20000",   "publisherProtocol" : "http",   "publisherTopicName" : "unauthenticated.DCAE_CL_OUTPUT",   "subscriberConsumerGroup" : "OpenDCAE-c1",   "subscriberConsumerId" : "c1",   "subscriberContentType" : "application/json",   "subscriberHostName" : "10.12.25.96",   "subscriberHostPort" : "3904",   "subscriberMessageLimit" : "-1",   "subscriberPollingInterval" : "20000",   "subscriberProtocol" : "http",   "subscriberTimeoutMS" : "-1",   "subscriberTopicName" : "unauthenticated.SEC_MEASUREMENT_OUTPUT",   "enableAAIEnrichment" : false,   "aaiEnrichmentHost" : "10.12.25.72",   "aaiEnrichmentPortNumber" : 8443,   "aaiEnrichmentProtocol" : "https",   "aaiEnrichmentUserName" : "DCAE",   "aaiEnrichmentUserPassword" : "DCAE",   "aaiEnrichmentIgnoreSSLCertificateErrors" : true,   "aaiVNFEnrichmentAPIPath" : "/aai/v11/network/generic-vnfs/generic-vnf",   "aaiVMEnrichmentAPIPath" :  "/aai/v11/search/nodes-query",   "tca_policy" : "{         \"domain\": \"measurementsForVfScaling\",         \"metricsPerEventName\": [{                 \"eventName\": \"vFirewallBroadcastPackets\",                 \"controlLoopSchemaType\": \"VNF\",                 \"policyScope\": \"DCAE\",                 \"policyName\": \"DCAE.Config_tca-hi-lo\",                 \"policyVersion\": \"v0.0.1\",                 \"thresholds\": [{                         \"closedLoopControlName\": \"ControlLoop-vFirewall-d0a1dfc6-94f5-4fd4-a5b5-4630b438850a\",                         \"version\": \"1.0.2\",                         \"fieldPath\": \"$.event.measurementsForVfScalingFields.vNicUsageArray[*].receivedTotalPacketsDelta\",                         \"thresholdValue\": 300,                         \"direction\": \"LESS_OR_EQUAL\",                         \"severity\": \"MAJOR\",                         \"closedLoopEventStatus\": \"ONSET\"                 }, {                         \"closedLoopControlName\": \"ControlLoop-vFirewall-d0a1dfc6-94f5-4fd4-a5b5-4630b438850a\",                         \"version\": \"1.0.2\",                         \"fieldPath\": \"$.event.measurementsForVfScalingFields.vNicUsageArray[*].receivedTotalPacketsDelta\",                         \"thresholdValue\": 700,                         \"direction\": \"GREATER_OR_EQUAL\",                         \"severity\": \"CRITICAL\",                         \"closedLoopEventStatus\": \"ONSET\"                 }]         }, {                 \"eventName\": \"vLoadBalancer\",                 \"controlLoopSchemaType\": \"VM\",                 \"policyScope\": \"DCAE\",                 \"policyName\": \"DCAE.Config_tca-hi-lo\",                 \"policyVersion\": \"v0.0.1\",                 \"thresholds\": [{                         \"closedLoopControlName\": \"ControlLoop-vDNS-6f37f56d-a87d-4b85-b6a9-cc953cf779b3\",                         \"version\": \"1.0.2\",                         \"fieldPath\": \"$.event.measurementsForVfScalingFields.vNicUsageArray[*].receivedTotalPacketsDelta\",                         \"thresholdValue\": 300,                         \"direction\": \"GREATER_OR_EQUAL\",                         \"severity\": \"CRITICAL\",                         \"closedLoopEventStatus\": \"ONSET\"                 }]         }, {                 \"eventName\": \"Measurement_vGMUX\",                 \"controlLoopSchemaType\": \"VNF\",                 \"policyScope\": \"DCAE\",                 \"policyName\": \"DCAE.Config_tca-hi-lo\",                 \"policyVersion\": \"v0.0.1\",                 \"thresholds\": [{                         \"closedLoopControlName\": \"ControlLoop-vCPE-48f0c2c3-a172-4192-9ae3-052274181b6e\",                         \"version\": \"1.0.2\",                         \"fieldPath\": \"$.event.measurementsForVfScalingFields.additionalMeasurements[*].arrayOfFields[0].value\",                         \"thresholdValue\": 0,                         \"direction\": \"EQUAL\",                         \"severity\": \"MAJOR\",                         \"closedLoopEventStatus\": \"ABATED\"                 }, {                         \"closedLoopControlName\": \"ControlLoop-vCPE-48f0c2c3-a172-4192-9ae3-052274181b6e\",                         \"version\": \"1.0.2\",                         \"fieldPath\": \"$.event.measurementsForVfScalingFields.additionalMeasurements[*].arrayOfFields[0].value\",                         \"thresholdValue\": 0,                         \"direction\": \"GREATER\",                         \"severity\": \"CRITICAL\",                         \"closedLoopEventStatus\": \"ONSET\"                 }]         }] }" }

 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

reload-tca.sh



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

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).
