Tags:数据 flume 常用 配置


配置一:主要是从目录获取数据并将数据写入hdfs

#定义agent名, source、channel、sink的名称

a4.sources = r1
a4.channels = c1
a4.sinks = k1


#具体定义source
a4.sources.r1.type = spooldir
a4.sources.r1.spoolDir = /home/hadoop/logs


#具体定义channel
a4.channels.c1.type = memory
a4.channels.c1.capacity = 10000
a4.channels.c1.transactionCapacity = 100


#定义拦截器,为消息添加时间戳
a4.sources.r1.interceptors = i1
a4.sources.r1.interceptors.i1.type = org.apache.flume.interceptor.TimestampInterceptor$Builder




#具体定义sink
a4.sinks.k1.type = hdfs
a4.sinks.k1.hdfs.path = hdfs://ns1/flume/%Y%m%d
a4.sinks.k1.hdfs.filePrefix = events-
a4.sinks.k1.hdfs.fileType = DataStream
#不按照条数生成文件
a4.sinks.k1.hdfs.rollCount = 0
#HDFS上的文件达到128M时生成一个文件
a4.sinks.k1.hdfs.rollSize = 134217728
#HDFS上的文件达到60秒生成一个文件
a4.sinks.k1.hdfs.rollInterval = 60


#组装source、channel、sink
a4.sources.r1.channels = c1

a4.sinks.k1.channel = c1



配置二:从目录中读取数据写入到日志文件

#定义agent名, source、channel、sink的名称
a3.sources = r1
a3.channels = c1
a3.sinks = k1


#具体定义source
a3.sources.r1.type = spooldir
a3.sources.r1.spoolDir = /root/logs


#具体定义channel
a3.channels.c1.type = memory
a3.channels.c1.capacity = 1000
a3.channels.c1.transactionCapacity = 100


#具体定义sink
a3.sinks.k1.type = logger


#组装source、channel、sink
a3.sources.r1.channels = c1
a3.sinks.k1.channel = c1



配置三:从命令行中得到数据并输出到日志文件

#bin/flume-ng agent -n a2 -f /home/hadoop/a2.conf -c conf -Dflume.root.logger=INFO,console
#定义agent名, source、channel、sink的名称
a2.sources = r1
a2.channels = c1
a2.sinks = k1


#具体定义source
a2.sources.r1.type = exec
a2.sources.r1.command = tail -F /home/hadoop/a.log


#具体定义channel
a2.channels.c1.type = memory
a2.channels.c1.capacity = 1000
a2.channels.c1.transactionCapacity = 100


#具体定义sink
a2.sinks.k1.type = logger


#组装source、channel、sink
a2.sources.r1.channels = c1
a2.sinks.k1.channel = c1


配置四:监听某一个端口将流经端口的数据捕获写入到日志

#定义agent名, source、channel、sink的名称
a1.sources = r1
a1.channels = c1
a1.sinks = k1


#具体定义source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 8888


#具体定义channel
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100


#具体定义sink
a1.sinks.k1.type = logger


#组装source、channel、sink
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
