Overview

DataFile Collector provides ONAP Operators the ability to upload PM XML Files from PNFs, by sending a fileReady VES Event. These files are published to the DataRouter for further use within ONAP.

DataFile Collector Sequence Diagram 1

Bulk PM Flow:

  1. NF notifies DCAE that a PM file is available for upload.
  2. DataFile Collector uploads PM Files from NF and stores them in Data Router.
  3. PM Mapper creates custom Performance events (VES) from the PM File data according to PM Mapping File.
  4. Analytics Applications use these performance events for targeted analysis of network operations.
