Flow Collector
Overview
The Unified Assurance Flow Collector microservice is part of the microservice flow pipeline. The microservice is responsible for receiving, decoding, transforming, normalizing, translating and enriching network flow records and telemetry sent from network devices and applications using IPFIX, Netflow, sFlow and AWS VPC Flow Logs. The resulting records are then sent to the flow analytics database and can be viewed in the flow analytics dashboards.
Prerequisites
-
The ElasticSearch database must be configured and running before setting up this microservice.
-
A microservice cluster must be setup. Refer to Microservice Cluster Setup.
