Edge Infrastructure Analytics complementing 5G VNF Analytics
- Increase the accuracy of placement decisions
- Addresses gap in cloud provider solution – e.g. open source OpenStack does not have a comprehensive telemetry solution

ONAP, as in R2, collects the statistics/alarms/events from workloads (VMs) and take any close loop control actions such as Heal a process, scale-out, restart etc.. In R3 and beyond, infrastructure related statistics/alarms/events will be collected, generate actionable insights and take life cycle actions on the workloads. Infrastructure statistics normally include performance counters, NIC counters, IPMI information on per physical server node basis. To reduce the load on the ONAP, it is necessary that aggregated (summarized) information is sent to the ONAP from edge-clouds.
As part of this activity, intention is to create aggregation micro-service that collects the data from physical nodes (over collected and other mechanisms), aggregate the information (time based aggregation, threshold based aggregation, silencing etc.,..) based on the configurable rules and export the aggregate data to DCAE. This micro service can be instantiated by ONAP itself - one or more instances for edge-clouds at the ONAP-central itself using OOM, it could be instantiated at the edge-cloud using their own deployment tools or it could be deployed edge service providers at the regional site level.
In R3, functionality is limited to HPA features and visualization. R3 stretch goal: It collects information from each compute node for all HPA features and keeps track of health and resource information. It would use this information in placement decisions by OOF for accurate results.
Even though the aggregation service is being developed in Multi-Cloud project, it is expected that this can be deployed at various places. The decision to deploy at various levels can be due to performance and regulatory reasons. Following deployments are envisaged at this time:
- At the edge site level.
- At the regional site level (on behalf of set of edge sites).
- At the ONAP level (on behalf of set of edge sites)
