# Agents

There are various agents that can send samples to a flow collector.

## Hardware

Sample configuration:
```
set protocols sflow collector 10.0.0.1
set protocols sflow collector udp-port 6343
set protocols sflow interface ge-0/0/0
set protocols sflow sample-rate 2048
```

## Software

### hsflowd

[Documentation](https://sflow.net/host-sflow-linux-config.php).

Sample packets using pcap, iptables nflog and many more. Uses sFlow.
