InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
This tool should help with the UDP duplication beyond the two target challenge with iptables: https://github.com/sleinen/samplicator - still, some additional details on the app/data being transmitted would help; data actually push only?

It's part of the statsd_exporter.
