Flume agent

Flume agent is the smallest possible deployment comprising of Source, Channel and Sink as its main components. The following figure shows a typical Flume agent deployment:

Figure 14: Flume Agent components

Flume agent is a Java daemon which received event from a source and then passes onto a channel, where it is usually written to the disk (according to reliability level set) and then moves the event to the sink. When the sink receives the event it sends acknowledgement back to channel and channel erases the event from its store. The agent has a very small memory footprint (-Xmx20m) and can be controlled declaratively using configurations.

Flume agent configurations

Some of these aspects have been unintentionally discussed in details in the Flume architecture section, however we thought that separate section for these agent configuration is required. Since we don't want to repeat ourselves, we will be referring some aspects back to that section.
