-$h1 Flume Appender
-
-The Flume Appender allows applications to send events to Flume Agents.
-
-$h2 Remote Agent
-
-Including the Log4j flume-ng jar in your Maven-based project as a dependency should cause all the
-transitive dependencies necessary for the remote Agent to function to be included.
-
-$h2 Persistent Agent
-
-The persistent agent uses Berkeley DB. The following dependency should be added to your pom.xml
-in addition to the log4j-flume-ng dependency.
