## 1.监控 netcat 端口数据案例 ##

选型：`netcat source` \+ `memory channel` \+ `logger sink`

## 2.需求图示 ##

## 3.flume配置 ##

flume-netcat-logger.conf

# Name the components on this agent
    a1.sources = r1
    a1.sinks = k1
    a1.channels = c1
    
    # Describe/configure the source
    a1.sources.r1.type = netcat
    a1.sources.r1.bind = localhost
    a1.sources.r1.port = 44444
    
    # Describe the sink
    a1.sinks.k1.type = logger
    
    # Use a channel which buffers events in memory
    a1.channels.c1.type = memory
    a1.channels.c1.capacity = 10000
    a1.channels.c1.transactionCapacity = 10000
    a1.channels.c1.byteCapacityBufferPercentage = 20
    a1.channels.c1.byteCapacity = 800000
    
    # Bind the source and sink to the channel
    a1.sources.r1.channels = c1
    a1.sinks.k1.channel = c1

## 4.启动命令 ##

bin/flume-ng agent -c conf -n a1 -f job/flume-netcat-logger.conf -Dflume.root.logger=INFO,console

## 5.测试图示 ##

> **netcat 发送数据，flume 端能够正常接收，通过 logger 方式输出，如图所示：**
