   1 DCAE mS Installation
   2 ====================
   3
   4 The below steps covers manual setup of DCAE VM’s and DCAE service
   5 components.
   6
   7 VESCollector
   8 ------------
   9
  10
  11
  12 DCAE VES Collector can be configured on VM with ubuntu-16.04 image
  13 (m1.small should suffice if this is only service) and 20Gb cinder
  14 storage
  15
  16 1. Install docker
  17
  18   sudo apt-get update
  19
  20   sudo apt install `docker.io <http://docker.io/>`__
  21
  22 1. Pull the latest container from onap nexus
  23
  24     sudo docker login -u docker -p docker
  25     `nexus.onap.org <http://nexus.onap.org/>`__:10001
  26
  27     sudo docker pull
  28     `nexus.onap.org <http://nexus.onap.org/>`__:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:1.1
  29
  30 1. Start the VESCollector with below command
  31
  32     sudo docker run -d --name vescollector -p 8080:8080/tcp -p
  33     8443:8443/tcp -P -e DMAAPHOST='<dmaap IP>'
  34     `nexus.onap.org <http://nexus.onap.org/>`__:10001/onap/org.onap.dcaegen2.collectors.ves.vescollector:1.1
  35
  36      Note:  Change the dmaaphost to required DMAAP ip. To change the
  37     dmaap information for a running container,  stop the active
  38     container and rerun above command changing the dmaap IP.
  39
  40 1. Verification
  41
  42 i.  Check logs under container /opt/app/VESCollector/logs/collector.log
  43         for errors
  44
  45 ii. If no active feed, you can simulate an event into collector via curl
  46
  47     curl -i  -X POST -d @<sampleves> --header "Content-Type:
  48     application/json" http://localhost:8080/eventListener/v5 -k
  49
  50     Note: If DMAAPHOST provided is invalid, you will see exception
  51     around publish on the collector.logs (collector queues and attempts
  52     to resend the event hence exceptions reported will be periodic).
  53
  54 i. Below two topic configuration are pre-set into this container.  When
  55        valid DMAAP instance ip was provided and VES events are received,
  56        the collector will post to below topics.
  57
  58     Fault -
  59      http://<dmaaphost>:3904/events/unauthenticated.SEC\_FAULT\_OUTPUT
  60
  61     Measurement
  62     -http://<dmaaphost>:3904/events/unauthenticated.SEC\_MEASUREMENT\_OUTPUT
  63
  64 VM Init
  65 ~~~~~~
  66
  67 To address windriver server in-stability, the below **init.sh** script
  68 was used to start the container on VM restart.

 103 ThresholdCrossingAnalysis (TCA/CDAP)
 104 ------------------------------------
 105
 106 The platform deploys CDAP as cluster and instantiates TCA. For the
 107 manual setup, we will leverage the CDAP SDK docker container to deploy
 108 TCA instances.  To setup TCA, choose VM with ubuntu-16.04 image,
 109 m1.medium size and 50gb cinder volumes.
 110
 111 1. Install docker
 112
 113      sudo apt-get update
 114
 115      sudo apt install `docker.io <http://docker.io/>`__
 116
 117 1. Pull CDAP SDK container
 118
 119 sudo docker pull caskdata/cdap-standalone:4.1.2
 120
 121 1. Deploy and run the CDAP container
 122
 123     sudo docker run -d --name cdap-sdk-2 -p 11011:11011 -p 11015:11015
 124     caskdata/cdap-standalone:4.1.2
 125
 126 1. Create Namespace on CDAP application
 127
 128 curl -X PUT http://localhost:11015/v3/namespaces/cdap_tca_hi_lo
 129
 130 1. Create TCA app preference file under ~ubuntu as below
