Adding multiple flows in an agentA single Flume agent can contain several independent flows. You can list. multiple sources, sinks and channels in a config. These components can be.

For example, if. you need to setup two flows in an agent, one going from an external avro client. HDFS and another from output of a tail to avro sink, then heres a. App. Srv source. Cluster. App. Srv source. Cluster. Configuring a multi agent flowTo setup a multi tier flow, you need to have an avrothrift sink of first hop. This will result in the first. Flume agent forwarding events to the next Flume agent. For example, if you are. Flume agent, then this local agent can forward it to another agent that has the.

HDFS agent config list sources, sinks and channels in the agentagentfoo. Here we link the avro forward sink from the weblog agent to the. This will result in the events coming. HDFS. Fan out flowAs discussed in previous section, Flume supports fanning out the flow from one. There are two modes of fan out, replicating and. In the replicating flow, the event is sent to all the configured. In case of multiplexing, the event is sent to only a subset of. To fan out the flow, one needs to specify a list of. Casa De Sanatate Bihor Program there. This is done by. adding a channel selector that can be replicating or multiplexing. Then. further specify the selection rules if its a multiplexer.

This requires specifying a mapping of an event attribute to a set for channel. The selector checks for each configured attribute in the event header. If it. matches the specified value, then that event is sent to all the channels mapped. If theres no match, then the event is sent to set of channels. Mapping for multiplexing selectorlt Agent.
