Deployment Automation 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
...
- 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
- TCA application
- Supported service assurance policies on VMware producton 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
...
- 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 Smart 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
