我有什么似乎是一个简单的Flume配置，这是给我很多问题。让我先描述一下问题，然后列出配置文件。
我有3台服务器：server1，server2，server3。
server1:netcat source/syslogtcp source（我在没有acks的netcat和syslogtcp上都测试过这个）2个内存通道2个avro接收器（每个通道一个）复制选择器，第二个内存通道可选
server2,3:avro源内存通道kafka接收器
在我的模拟中，server2模拟“生产”，因此不会发生任何数据丢失，而server3模拟“开发”，数据丢失很好。我的假设是，使用2个通道和2个源将使这两个服务器彼此解耦，如果server3宕机，它将不会影响sever2（特别是使用可选配置选项！）。然而，事实并非如此。当我运行我的模拟并用ctrl-c终止server3时，我在server2上遇到了减速，从server2到kafka接收器的输出变成了爬行。当我恢复server3上的flume代理时，一切都恢复正常。
我没想到会有这种行为。我所期望的是，因为我有两个通道和两个接收器，如果一个通道和/或接收器坏了，另一个通道和/或接收器应该没有问题。这是Flume的限制吗？这是我的源、汇或通道的限制吗？有没有一种方法让flume在我使用一个代理的情况下运行，其中多个通道和接收器相互解耦？我真的不想在一台机器上为每个“环境”（生产和开发）设置多个flume代理。附件是我的配置文件，以便您可以更专业地查看我所做的工作：
服务器1（第一层代理）
