Receive request for specific KPI computation (future scope) on specific ‘objects’ (e.g., S-NSSAI, Service)
Architecture Diagram
KPI flows：
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 MS will support for periodical KPI Computation. Period may be specified by a requestor optionally, if nothing is specified, KPI computation MS will continue computation until an explicit stop trigger is received.
4. The KPI result which genertate by kpi computation will be published to DMaaP.
