Introduction to IBM biginsights Flume
Flume is an open source mass log collection system that supports real-time collection of logs. The initial flume version was Flume OG (flume original Generation), developed by Cloudera company, called Cloudera Flume; later, Cloudera contributed to Apache, the version to FL UME NG (Flume Next generation) is now known as Apach

Preface
When the system is large, it will be split into multiple independent processes, such as Web + WCF/web API, and become a distributed system.
It is difficult to see how a request goes from start to end. If debugging and tracking are performed, the problem is more complicated. The difficulty depends on the number of processes.

Flume Knowledge Points:Event is a row of data1.flume is a distributed log collection system that transmits collected data to its destination.2.flume has a core concept, called an agent. The agent is a Java process that runs on the Log collection node.The 3.agent consists of 3 core components: source, channel, sink.The
