我刚开始使用水槽,需要在 hdfs 接收器中插入一些标题。
虽然格式错误并且我无法控制列,但我有这个工作。
使用此配置:
a1.sources = r1
a1.sinks = k1
a1.channels = c1
a1.sources.r1.type = syslogudp
a1.sources.r1.host = 0.0.0.0
a1.sources.r1.port = 44444
a1.sources.r1.interceptors = i1 i2
a1.sources.r1.interceptors.i1.type = org.apache.flume.interceptor.HostInterceptor$Builder
a1.sources.r1.interceptors.i1.preserveExisting = false
a1.sources.r1.interceptors.i1.hostHeader = hostname
a1.sources.r1.interceptors.i2.type = org.apache.flume.interceptor.TimestampInterceptor$Builder
a1.sources.r1.interceptors.i2.preserveExisting = false
a1.sinks.k1.type = hdfs
a1.sinks.k1.hdfs.path = hdfs://localhost:9000/user/vagrant/syslog/%y-%m-%d/
a1.sinks.k1.hdfs.rollInterval = 120
a1.sinks.k1.hdfs.rollCount = 100
a1.sinks.k1.hdfs.rollSize = 0
a1.sinks.k1.hdfs.fileType = DataStream
a1.sinks.k1.hdfs.writeFormat = Text
a1.sinks.k1.serializer = header_and_text
a1.sinks.k1.serializer.columns = timestamp hostname
a1.sinks.k1.serializer.format = CSV
a1.sinks.k1.serializer.appendNewline = true
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
写入HDFS的日志除了序列化的方面主要是ok的:
{timestamp=1415574695138, Severity=6, host=PolkaSpots, Facility=3, hostname=127.0.1.1} hostapd: wlan0-1: STA xx WPA: group key handshake completed (RSN)
如何格式化日志,使它们看起来像这样:
1415574695138 127.0.1.1 hostapd: wlan0-1: STA xx WPA: group key handshake completed (RSN)
时间戳首先是主机名,然后是系统日志消息正文。
