flume实战：监控文件所追加内容

一：agent配置文件内容

# 声明agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1

# 监控test.log文件追加内容
a1.sources.r1.type = exec
a1.sources.r1.command = tail -f /opt/software/flume/datas/test.log

# Describe the sink
a1.sinks.k1.type = logger

# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

二：演示，涉及到的两个命令

1、启动flume：bin/flume-ng agent -n a1 -c conf/ -f job/file_logger.conf -Dflume.root.logger=INFO,console

2、文件追加内容：示例：echo 123 >> test.log   追加不覆盖

注意：当r1.type为exec时，若所监控的该文件中已有内容，那么启动flume时，会默认先将原有的数据进行读取
