我正在尝试将单台计算机上不同目录的日志收集到本地文件系统文件或HDFS。
我已经注册了2个来源r1，r2。 两个源都指向单通道C1。 通道上有一个水槽。 K1
请在下面找到配置文件：
# Name the components on this agent
a1.sources = r1
a1.sources = r2
a1.sinks = k1
a1.channels = c1
a1.sources.r2.type = exec
a1.sources.r2.command = tail -f /PATH/bper-peg-pt-rest.log
a1.sources.r1.type = exec
a1.sources.r1.command = tail -f /PATH/bper-peg-ejb.log
# Describe the sink
a1.sinks.k1.type = file_roll
a1.sinks.k1.sink.directory = /home/vbsc/Desktop/flume_project_logging/logs_aggregated
a1.sinks.k1.sink.rollInterval = 0
# Use file channel
a1.channels.c1.type = file
# Bind the source and sink to the channel
a1.sinks.k1.channel = c1
a1.sources.r2.channels = c1
a1.sources.r1.channels = c1
但是当我使用Agent a1启动Flume时，只有一个源（r2）正在启动。 Flume代理启动日志：

由于
答案 0 :(得分：1)
我需要声明两个来源如下：
a1.sources = r1 r2
早些时候，我这样做是为了
a1.sources = r1
a1.sources = r2
所以只有一个来源被注册。
