1. KPI Computation MS will get PM data VES format from DMaaP
2. Other modules (e.g., SO/OOF/Slice Analysis MS) can also request KPI-MS for KPI calculation (Future scope beyond H-release).
3. KPI Computation can be triggered once PM data received. 
4. KPI Computation do calculation ,generate KPI result, publish the result to Dmaap. 

Current LimitationsStatus:

1. This ms provide a basic framework to support kpi computation, currently only support to do basic sum operation at present. more operation need to be extend in  the future.
2. This ms only support to do calculation base on the real-time pm data from dmaap which published by pm-mapper.
3. This ms can support to get formula from cbs.
4. KPI Computation do calculation ,generate KPI result, publish the result to Dmaap. 

Artifact

KPI ms can be dynamically deployed in DCAE’s Cloudify environment via its blueprint deployment artifact.
