您好,登录后才能下订单哦!
监听是一个目录,这个目录不能有子目录,监控的是这个目录下的文件。采集完成,这个目录下的文件会加上后缀(.COMPLETED)
配置文件:
#Name the components on this agent
#这里的a1指的是agent的名字,可以自定义,但注意:同一个节点下的agent的名字不能相同
#定义的是sources、sinks、channels的别名
a1.sources = r1
a1.sinks = k1
a1.channels = c1
#指定source的类型和相关的参数
a1.sources.r1.type = spooldir
a1.sources.r1.spoolDir = /home/hadoop/flumedata
#设定channel
a1.channels.c1.type = memory
#设定sink
a1.sinks.k1.type = logger
#Bind the source and sink to the channel
#设置sources的通道
a1.sources.r1.channels = c1
#设置sink的通道
a1.sinks.k1.channel = c1
一个NetCat Source用来监听一个指定端口,并将接收到的数据的每一行转换为一个事件。
数据源: netcat(监控tcp协议)
Channel:内存
数据目的地:控制台
配置文件
#指定代理
a1.sources = r1
a1.channels = c1
a1.sinks = k1
#指定sources
a1.sources.r1.channels = c1
#指定source的类型
a1.sources.r1.type = netcat
#指定需要监控的主机
a1.sources.r1.bind = 192.168.191.130
#指定需要监控的端口
a1.sources.r1.port = 3212
#指定channel

#sinks 写出数据 logger
a1.sinks.k1.channel=c1
a1.sinks.k1.type=logger
监听AVRO端口来接受来自外部AVRO客户端的事件流。利用Avro Source可以实现多级流动、扇出流、扇入流等效果。另外也可以接受通过flume提供的Avro客户端发送的日志信息。
数据源: avro
Channel:内存
数据目的地:控制台
配置文件
#指定代理
a1.sources = r1
a1.channels = c1
a1.sinks = k1

在一份agent中有多个channel和多个sink,然后多个sink输出到不同的文件或者文件系统中。
规划:

使用 exec “tail -F /home/hadoop/testlog/datalog.log”获取采集数据
使用 sink1 将数据 存储hdfs
使用 sink2 将数据都存储 控制台

首先在三个web服务器中收集数据,然后交给collect,此处的collect是高可用的,首先collect01是主,所有收集到的数据发送给他,collect02只是出于热备状态不接受数据,当collect01宕机的时候,collect02顶替,然后接受数据,最终将数据发送给hdfs或者kafka。
agent和collecotr的部署
Agent1、Agent2数据分别流入到Collector1和Collector2中,Flume NG 本 身提供了 Failover 机制,可以自动切换和恢复。再由Collector1和Collector2将数据输出到hdfs中。
