1 # VNF Indicator collection using Prometheus exporters

19 VNF indicators are gathered today using Juju Metrics, which MON collects through N2VC.
20 Juju metrics present some limitations:
21 - Collection interval is fixed to 5m
22 - Metrics can only be collected through CLI
24 The original proposal to replace this with regular, periodic primitives, has been discarded as
25 primitives are 'blocking', so a metric collection primitive could delay a configuration primitive.
27 A mechanism is needed to collect indicators through SNMP, REST API and other methods, ideally:
28 - Adding 'exporters' to store metrics directly to the existing Prometheus TSDB.
29 - Trying to mantain alignment with current ETSI standards (SOL002, SOL006)
31 ## Demo or definition of done
33 VNF Indicator collection through SNMP (ant other methods) can be specified at the VNFD, with a
34 variable collection period, which will make the system enable the corresponding exporter and
35 show the metric at a Network Service dashboard in Grafana.
