嗨，我正在为代理使用下面的conf文件。
当我运行代理时，我没有在Flume文件夹中得到任何东西。有人能给我一些建议吗？

# Define a memory channel called ch1 on agent1

agent1.channels.ch1.type = memory

agent1.sources.spool.type = spooldir
agent1.sources.spool.channels = ch1
agent1.sources.spool.spoolDir = /logs/source
agent1.sources.spool.fileHeader = true

agent1.sinks.fr1.type = file_roll
agent1.sinks.fr1.channel = ch1
agent1.sinks.fr1.sink.directory = /logs/sink

agent1.channels = ch1
agent1.sources = spool
agent1.sinks = fr1
