Description

VNF indicators are gathered today using Juju Metrics, which MON collects through N2VC. Juju metrics present some limitations:

• Collection interval is fixed to 5m
• Metrics can only be collected through CLI

The original proposal to replace this with regular, periodic primitives, has been discarded as primitives are 'blocking', so a metric collection primitive could delay a configuration primitive.

A mechanism is needed to collect indicators through SNMP, REST API and other methods, ideally:

• Adding 'exporters' to store metrics directly to the existing Prometheus TSDB.
• Trying to mantain alignment with current ETSI standards (SOL002, SOL006)

Demo or definition of done

VNF Indicator collection through SNMP (ant other methods) can be specified at the VNFD, with a variable collection period, which will make the system enable the corresponding exporter and show the metric at a Network Service dashboard in Grafana.
