Sources, channels, and sinks
The Flume agent's architecture can be viewed in this simple diagram. Inputs are called sources and outputs are called sinks. Channels provide the glue between sources and sinks. All of these run inside a daemon called an agent.
Note
Keep in mind:
- A source writes events to one or more channels.
- A channel is the holding area as events are passed from a source to a sink.
- A sink receives events from one channel only.
- An agent can have many channels.
