  1. Slice analysis ms consumes PM messages from PERFORMANCE_MEASUREMENTS topic
  2. For analysis Slice analysis MS consumes various data from Config DB
    1. List of Network Functions which serves the snssai
    2. List of RICs and its corresponding cell mappings of the snssai
    3. Current Configuration of the RICs
    4. Slice Profile of the snssai
    5. Subscriber details of the snssai (for sending the onset message to policy)
  3. With the help of pm data, Slice analysis MS computes the DLThptPerSlice and ULThptPerSlice for the RICs of the snssai, and the computed value is compared with the current configuration of the RICs.
  4. If the change in configuration exceeds the minimum percentage value which is kept as a configuration parameter, then the closed-loop will be triggered by posting the onset message to DMAAP

Deployment Prerequisite/dependencies

  1. DCAE and DMaaP pods should be up and running. 

  2. DMaaP Bus Controller PostInstalls job should have completed successfully (executed as part of an OOM install).
  3. PM mapper service should be running.
  4. Config DB service should be running.
  5. Make sure that cfy is installed and configured to work with the Cloudify deployment.

Deployment Steps

Architecture

 Image Added

DMAAP Client - creates a thread pool for every DMAAP topic consumer. The thread polls the DMAAP topic for every configured time interval and whenever a message is received it stores that message in the Postgres DB.

PM Thread - reads the PM event from the database and puts the PM sample in the internal queue in the format which is needed for further processing.

Consumer Thread - Consumes pm samples from the internal queue and make all the required Config DB calls, perform the analysis, and puts the onset message to the DMAAP topic

Deployment Prerequisite/dependencies

  1. DCAE and DMaaP pods should be up and running. 

  2. DMaaP Bus Controller PostInstalls job should have completed successfully (executed as part of an OOM install).
  3. PM mapper service should be running.
  4. Config DB service should be running.
  5. Make sure that cfy is installed and configured to work with the Cloudify deployment.

Deployment Steps

  1. Execute bash on the bootstrap Kubernetes pod. 

    Code Block
    languagebash
    themeEmacs
    kubectl -n onap exec -it <dcaegen2-dcae-bootstrap> bash


  2. Go to the /blueprints directory.

  3. Check that the tag_version in the slice-analysis-ms blueprint is correct for the release of ONAP that it is being installed on see Nexus link for slice-analysis-ms for tag_versions
  4. Refer blueprints for sliceanalysis ms: https://gerrit.onap.org/r/gitweb?p=dcaegen2%2Fplatform%2Fblueprints.git;hb=refs%2Fchanges%2F20%2F114120%2F3;f=blueprints%2Fk8s-slice-analysis-ms.yaml

  5. Create an input file.        

    Expand
    titleSample k8s-slice-input.yaml

    tag_version: nexus3.onap.org:10001/onap/org.onap.dcaegen2.services.components.slice-analysis-ms:1.0.1
    config_db: http://<ip>:<port>
    initialDelaySeconds: 50000

    6.

    6. Execute bash on the bootstrap Kubernetes pod. 

    Code Block
    languagebash
    themeEmacs
    kubectl -n onap exec -it <dcaegen2-dcae-bootstrap> bash

  6. Go to the /blueprints directory.

  7. Check that the tag_version in the slice-analysis-ms blueprint is correct for the release of ONAP that it is being installed on see Nexus link for slice-analysis-ms for tag_versions
  8. Create an input file. 

  9. Run the Cloudify install command to install the slice-analysis-ms with the blueprint and the newly created input file k8s-slice-input.yaml.

    Code Block
    languagebash
    themeEmacs
    $ cfy install k8s-slice-analysis-ms.yaml -i  k8s-slice-input.yaml --blueprint-id sliceanalysisms


    Expand
    titleSample output
    $ cfy install k8s-slice-analysis-ms.yaml -i k8s-slice-input.yaml --blueprint-id sliceanalysisms
