Flume----企业开发案例之聚合

使用三台节点，b02master 上的agent1 监控文件/root/test.log，b02slave1上的agent2监控某一个端口的数据流，agent1和agent2将数据发送给 b02slave2 上的agent3最终数据打印到控制台

agent1.conf

# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /root/test.log
a1.sources.r1.shell = /bin/bash -c

# Describe the sink
a1.sinks.k1.type = avro
a1.sinks.k1.hostname = b02slave2
a1.sinks.k1.port = 520

# Describe the channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

agent2.conf

# Name the components on this agent
a2.sources = r1
a2.sinks = k1
a2.channels = c1

# Describe/configure the source
a2.sources.r1.type = netcat
a2.sources.r1.bind = b02slave1
a2.sources.r1.port = 44444

# Describe the sink
a2.sinks.k1.type = avro
a2.sinks.k1.hostname = b02slave2
a2.sinks.k1.port = 520

# Use a channel which buffers events in memory
a2.channels.c1.type = memory
a2.channels.c1.capacity = 1000
a2.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a2.sources.r1.channels = c1
a2.sinks.k1.channel = c1

agent3.conf

# Name the components on this agent
a3.sources = r1
a3.sinks = k1
a3.channels = c1

# Describe/configure the source
a3.sources.r1.type = avro
a3.sources.r1.bind = b02slave2
a3.sources.r1.port = 520

# Describe the sink
a3.sinks.k1.type = logger

# Describe the channel
a3.channels.c1.type = memory
a3.channels.c1.capacity = 1000
a3.channels.c1.transactionCapacity = 100
# Bind the source and sink to the channel
a3.sources.r1.channels = c1
a3.sinks.k1.channel = c1

启动命令

bin/flume-ng agent -c conf -f conf/group3/agent1.conf -n a1 -Dflume.root.logger=INFO,console
bin/flume-ng agent -c conf -f conf/group3/agent2.conf -n a2 -Dflume.root.logger=INFO,console
bin/flume-ng agent -c conf -f conf/group3/agent3.conf -n a3 -Dflume.root.logger=INFO,console

实现流程

1. 在三台设备上分别进行
2. 在不同的节点上运行agent1，2，3
3. agent1采集test,log
4. agent2采集nc端口上发送的数据
5. agent3对里面的数据进行聚合
