flume-ng 问题处理（1）

1,flume日志报错，同时没能正常收集相关日志文件

Caused by: org.apache.flume.ChannelException: Space for commit to queue couldn't be acquired Sinks are likely not keeping up with sources, or the buffer size is too tight
        at org.apache.flume.channel.MemoryChannel$MemoryTransaction.doCommit(MemoryChannel.java:126)
        at org.apache.flume.channel.BasicTransactionSemantics.commit(BasicTransactionSemantics.java:151)
        at org.apache.flume.channel.ChannelProcessor.processEventBatch(ChannelProcessor.java:192)
        ... 28 more
        
2，根据网络上的方法，修改了一下参数

agent.channels.memoryChanne3.keep-alive = 60
agent.channels.memoryChanne3.capacity = 1000000

修改java最大内存大小
vi bin/flume-ng
JAVA_OPTS="-Xmx2048m"
3, 重启了所有flume程序，包括客户端和服务器端，以后是否还有问题，只能继续观察了
