Dublin and Beyond

Deployment Automation Workflow:

  • Init
    1. Deploy Normalization Microservice as part of ONAP Central
  • On Demand
    1. Deploy Edge Analytics App in Edge CloudApp 
    2. Create Kafka topic “edge-analytics-central-<id>” in DMaaP (Kafka) broker for publishing alarm from normalization microservice in ONAP format
    3. Program DMaaP (Kafka) client in normalization microservice to publish on “edge-analytics-central-<id>”
    4. Program DMaaP (Kafka) client in Policy to subscribe to “edge-analytics-central-<id>”

 Operational Workflow:

  • Support the following alerts
    • Host Aggregate/Cluster CPU usage exceeded a programmed threshold in the edge cloud
    • Host Aggregate/Cluster Memory usage exceeded a programmed threshold in the edge cloud
    • Host Aggregate/Cluster CPU & Memory usage exceeded a programmed thresholds in the edge cloud
  • ONAP Central normalization microservice receives alerts from Edge Analytics App through REST interface
  • ONAP Central normalization microservice publishes the above alerts on “edge-analytics-central-<id>” DMaaP (kafka) topic in ONAP format mapping from VM to relevant VNF by querying A&AI
  • Policy receives alerts on “edge-analytics-central-<id>” DMaaP (kafka) topic in ONAP format (leverage the current format between DCAE TCA App and Policy -- https://wikilf-onap.onapatlassian.orgnet/wiki/display/DW/TCA+application)
    • Policy to perform VNF scale out

 Assumptions:

  • Edge Cloud supports OpenStack and K8S
  • Edge Analytics App is manually configured – configuration automation involves APP-C and out of scope for this effort
  • ONAP Central Normalization microservice is a separate repo in multi-cloud

Dublin Scope

Goal

  • Develop basic service assurance microservice supporting ONAP Threshold Crossing Alert (TCA) format 
  • Supported service assurance policies on VMware Service Assurance Application
    • Host CPU usage exceeded a programmed threshold in the edge cloud
    • Host Memory usage exceeded a programmed threshold in the edge cloud
    • Host CPU & Memory usage exceeded a programmed thresholds in the edge cloud
    • Alert reporting format
      • Will report VMs which are part of the affected host
  • Hardcoding of various parameters acceptable

Stretch Goals

  • vRops VMware service assurance product integration testing
  • ONAP Lab Integration 
  • Create Kafka topic “edge-analytics-central-<id>” in DMaaP (Kafka) broker for publishing alert from "service-assurance" normalization microservice in ONAP TCA format 

Key Dublin Work Items

  • Helm Chart and Dockerfile for "service-assurance" Normalization Microservice  - Ramki - mostly complete
  • vRops VMware  Service Assurance Product Analytics API investigation for TCA w/ future proofing for Smarts - Girish/Ramki - in progress
  • Code Initial code development for "service-assurance" Normalization Microservice - TBD ( expected to be 2 weeks or less)
    • Program DMaaP (Kafka) client in normalization microservice to publish on “edge-analytics-central-<id>”
    • Receive TCA Alert using vROps API and publish on “edge-analytics-central-<id>”

vROps References

...

  • 1 week - this code will go into demo repository
    • Receive TCA Alert from VMware Service Assurance product Kafka interface on pre-specified VMware Service Assurance Application Kafka topic 
    • Convert TCA Alert to ONAP format – (leverage the current format between DCAE TCA App and Policy -- TCA application)
      • Map VM in Alert message to relevant VNF by querying A&AI
    • Publish TCA Alert to ONAP on pre-specified ONAP DMaaP (Kafka) topic
