I highly recommend pmacct and it's in-memory tables. Lightweight, easy to
query and super fast.

You can also easily run multiple aggregates of traffic to find what you are
interested in, tag common interface types to easily filter traffic..

Or you can use pmacct to insert this into whatever database you want, AMQP
or MongoDB..

My current favorite is using an IMT table for DoS detection and another for
aggregates for interesting traffic types and querying this every X minutes
and inserting it into ElasticSearch. Kibana makes the most powerful netflow
dashboard ever.
