To get data straight from network devices PacketBeat could support SFLOW.  
It's open and some more info here: [https://sflow.org/sFlowOverview.pdf](https://sflow.org/sFlowOverview.pdf)

This way I could configure our routers/switches to send flows straight to packetbeat processor for analysis.

Sample Arista Switch:

Just wanted to add that we would also really like sflow support. Alcatel switches don't support netflow. Or maybe a Logstash module such as the one for Netflow?

There _is_ an sFlow input for logstash. Simply run...

```auto
logstash/bin/logstash-plugin install logstash-codec-sflow

```

This codec is used by [**ElastiFlow**](https://github.com/robcowart/elastiflow) to decode sFlow records.
