Dublin and Beyond
Deployment Automation Workflow:
- Init
- Deploy Normalization Microservice as part of ONAP Central
- On Demand
- Deploy Edge Analytics App in Edge CloudApp
- Create Kafka topic “edge-analytics-central-<id>” in DMaaP (Kafka) broker for publishing alarm from normalization microservice in ONAP format
- Program DMaaP (Kafka) client in normalization microservice to publish on “edge-analytics-central-<id>”
- 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 multi cloud 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
- TCA application
- 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 "multicloud-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
