Analytics Normalization Efforts (In progress)

Dublin and Beyond

1. Deploy Normalization Microservice as part of ONAP Central
On Demand
1. Deploy Edge Analytics App
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>”

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://lf-onap.atlassian.net/wiki/display/DW/TCA+application)
- Policy to perform VNF scale out

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

Develop basic service assurance microservice supporting ONAP Threshold Crossing Alert (TCA) format
- TCA application
  - TCA format explained in "Table 1: Format of the Output Alert from the cdap-tca-hi-lo Microservice"
- Policy R3 Casablanca - Control Loop Operational Policy
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

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

Helm Chart and Dockerfile for "service-assurance" Normalization Microservice - Ramki - mostly complete
VMware Service Assurance Product Analytics API investigation for TCA w/ future proofing for Smarts - Girish/Ramki - in progress
Initial code development for "service-assurance" Normalization Microservice - expected to be 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
