...

3)      Start the VESCollector with below command
...
                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
Check logs under container /opt/app/VESCollector/logs/collector.log for errors
If no active feed, you can simulate an event into collector via curl

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