一、Timestamp Interceptor
在 event headers 中,添加 timestamp 標簽
[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
=== 結果
Event: { headers:{timestamp=1452668731658} body: 78 78 xx }
二、Host Interceptor
獲取 agent 部署那臺 server 的 ip 或是 hostname,或添加到 host 標簽中
[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 設置為 false,則獲取的值為 hostname
#agent.sources.exec_tail.interceptors.i2.hostHeader = hostname = default:header 中 key 為 host, 可以設置更改
#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=${ip}} body: 78 78 xx }
三、Static Interceptor
自定義向 header 中添加 k -v: 用途,如想知道 events 是那個 dc 的,那個 country,那個 city。也可以根據這些 header 信息,進行數據分流等等
[root@hftest0001 conf]# pwd
/opt/apache-flume-1.6.0-bin/conf
[root@hftest0001 conf]# vi s-exec_c-m_s-logger.conf
#agent.sources.exec_tail.interceptors.i2.userIP = false
#agent.sources.exec_tail.interceptors.i2.hostHeader = hostname
#agent.sources.exec_tail.interceptors.i2.preserveExisting = true
agent.sources.exec_tail.interceptors.i3.type = static
agent.sources.exec_tail.interceptors.i3.key = country
agent.sources.exec_tail.interceptors.i3.value = USA
agent.sources.exec_tail.interceptors.i4.type = static
agent.sources.exec_tail.interceptors.i4.key = city
agent.sources.exec_tail.interceptors.i4.value = NEW_YORK
agent.sinks.loggerSink.type = logger
#agent.sinks.loggerSink.maxBytesToLog = 1
agent.sinks.loggerSink.channel = memoryChannel
agent.channels.memoryChannel.type = memory
agent.channels.memoryChannel.capacity = 100
=== result
Event: { headers:{timestamp=1452669538967, host=${IP}, city=NEW_YORK, country=USA} body: 78 78 xx }
