This epic houses issues about the delivery of a custom consulting project whose assets are to include:

• A long-running Java program that:

  • Consumes call detail record (CDR) files from a filesystem directory

  • Translates the CDR files' CSV contents into time-series records conveying the MOS score of the described calls

  • Sends those time-series records to the Graphite telemetry listener on a Minion or core system

• A Groovy telemetry adapter script that maps the identifiers in the received time-series records to OpenNMS resources for persistence

• A Grafana dashboard that displays the data thus persisted
