## Introduction
This project provides support for receiving [NetFlow](https://en.wikipedia.org/wiki/NetFlow) data from network devices
using [Netty](http://netty.io). Currently only [NetFlow v9](https://en.wikipedia.org/wiki/NetFlow#NetFlow_and_IPFIX) is supported. There are plans to
support [NetFlow v5](https://en.wikipedia.org/wiki/NetFlow#NetFlow_Versions) in a future release.
## Usage
### Pipeline Configuration
```java
Bootstrap b = new Bootstrap();
b.group(bossGroup)
.channel(NioDatagramChannel.class)
.handler(new ChannelInitializer() {
@Override
protected void initChannel(DatagramChannel datagramChannel) throws Exception {
ChannelPipeline channelPipeline = datagramChannel.pipeline();
channelPipeline.addLast(
new LoggingHandler("NetFlow", LogLevel.TRACE),
new NetFlowV9Decoder(),
new NetFlowV9RequestHandler()
);
}
});
```
### NetFlow Message Processing
```java
class NetFlowV9RequestHandler extends SimpleChannelInboundHandler {
@Override
protected void channelRead0(ChannelHandlerContext channelHandlerContext, NetFlowV9Decoder.NetFlowMessage netFlowMessage) throws Exception {
}
}
```
