一、Timestamp Interceptor
在event headers中,添加timestamp标签
[root@hftest0001 conf]# pwd
/opt/apache-flume-1.6.0-bin/conf
[root@hftest0001 conf]# vi s-exec_c-m_s-logger.conf
agent.sources = exec_tail
agent.channels = memoryChannel
agent.sinks = loggerSink
agent.sources.exec_tail.type = exec
agent.sources.exec_tail.command = tail -F /opt/flume-data/exec-tail.log
agent.sources.exec_tail.channels = memoryChannel
agent.sources.exec_tail.interceptors = i1
agent.sources.exec_tail.interceptors.i1.type = timestamp
#agent.sources.exec_tail.interceptors.i1.preserveExisting = true
agent.sinks.loggerSink.type = logger
#agent.sinks.loggerSink.maxBytesToLog = 1
agent.sinks.loggerSink.channel = memoryChannel
agent.channels.memoryChannel.type = memory
agent.channels.memoryChannel.capacity = 100
===>结果
Event: { headers:{timestamp=1452668731658} body: 78 78 xx }
二、Host Interceptor
获取agent部署那台server的ip或是hostname,或添加到host标签中
[root@hftest0001 conf]# pwd
/opt/apache-flume-1.6.0-bin/conf
[root@hftest0001 conf]# vi s-exec_c-m_s-logger.conf
agent.sources.exec_tail.type = exec
agent.sources.exec_tail.command = tail -F /opt/flume-data/exec-tail.log
agent.sources.exec_tail.channels = memoryChannel
agent.sources.exec_tail.interceptors = i1 i2
agent.sources.exec_tail.interceptors.i1.type = timestamp
#agent.sources.exec_tail.interceptors.i1.preserveExisting = true
agent.sources.exec_tail.interceptors.i2.type = host
#agent.sources.exec_tail.interceptors.i2.userIP = false =>default:true 设置为false,则获取的值为hostname
#agent.sources.exec_tail.interceptors.i2.hostHeader = hostname => default:header中key为host,可以设置更改
#agent.sources.exec_tail.interceptors.i2.preserveExisting = true
agent.sinks.loggerSink.type = logger
#agent.sinks.loggerSink.maxBytesToLog = 1
agent.sinks.loggerSink.channel = memoryChannel
agent.channels.memoryChannel.type = memory
agent.channels.memoryChannel.capacity = 100
===>result
Event: { headers:{timestamp=1452669139164, host=${ip}} body: 78 78 xx }
三、Static Interceptor
自定义向header中添加k-v: 用途,如想知道events是那个dc的,那个country,那个city。也可以根据这些header信息,进行数据分流等等
[root@hftest0001 conf]# pwd
/opt/apache-flume-1.6.0-bin/conf
[root@hftest0001 conf]# vi s-exec_c-m_s-logger.conf
#agent.sources.exec_tail.interceptors.i2.userIP = false
#agent.sources.exec_tail.interceptors.i2.hostHeader = hostname
#agent.sources.exec_tail.interceptors.i2.preserveExisting = true
agent.sources.exec_tail.interceptors.i3.type = static
agent.sources.exec_tail.interceptors.i3.key = country
agent.sources.exec_tail.interceptors.i3.value = USA
agent.sources.exec_tail.interceptors.i4.type = static
agent.sources.exec_tail.interceptors.i4.key = city
agent.sources.exec_tail.interceptors.i4.value = NEW_YORK
agent.sinks.loggerSink.type = logger
#agent.sinks.loggerSink.maxBytesToLog = 1
agent.sinks.loggerSink.channel = memoryChannel
agent.channels.memoryChannel.type = memory
agent.channels.memoryChannel.capacity = 100
===> result
Event: { headers:{timestamp=1452669538967, host=${IP}, city=NEW_YORK, country=USA} body: 78 78 xx }
