How scalable is ElastiFlow ? Let say I will dump 90kflow/s, how big
elasticsearch farm do I need to comfortably store and work with at least
couple weeks of data ?

right now in NFSEN it takes about 3T in disk space and minutes for
simple reports if it spans few time default time intervals.

Thank you.

 +1 for ElastiFlow. Couldn't be easier to set up and run. Logstash has
native support for netflow and sflow now via codecs. Kibana is an
easy-to-use dashboard. I trimmed out a bunch of stuff in the ElastiFlow
config that assumed a unidirectional network (like a corporate site).

There is also https://github.com/robcowart/elastiflow which uses the ELK

Kentik is probably top of the foodchain right now.

But they are certainly not alone in the biz. Ontop of my head...

* Flowmon
* Talaia
* Arbor Peakflow
* Deepfield
* Pmacct + supporting toolkit
* NFsen/Nfdump/AS-stats
* Put kibana/ES infront of any collector

Logstash has a netflow plugin as of 5.x or something
(https://www.elastic.co/guide/en/logstash/current/netflow-module.html)
to
act as a collector.

A walkthrough:
http://www.routereflector.com/2017/07/elk-as-a-free-netflow-
ipfix-collector-and-visualizer/

Using the logstash module setup thing adds a whole bunch of pretty
netflow
graphs and visualizations and such into Kibana for you.

Caveat:
Supports netflow v5 and v9, but does not indicate support for IPFIX
explicitly.  It definitely does not support sFlow, though if you really
want you can stick sflowtool in front of it to translate sFlow->netflow,
e.g. http://blog.sflow.com/2011/12/sflowtool.html.

* Solarwinds something something
* Different vendor toolkits
