![]() ![]() To enable configuration-related logging, set the Java system property Must be set in addition to log4j properties. In order to enable logging of event- and configuration-related data, some Java system properties In some situations, however, this approach is insufficient. One way to debug problems with event pipelines is to set up an additional Memory ChannelĬonnected to a Logger Sink, which will output all event data to the Flume logs. On the other hand, if the data pipeline is broken,įlume will attempt to provide clues for debugging the problem. Many production environments because this may result in leaking sensitive data or security relatedĬonfigurations, such as secret keys, to Flume log files.īy default, Flume will not log such information. Logging the raw stream of data flowing through the ingest pipeline is not desired behavior in Given this configuration file, we can start Flume as follows: Several named agents when a given Flume process is launched a flag is passed telling it which named agent to manifest. Various components, then describes their types and configuration parameters. That buffers event data in memory, and a sink that logs event data to the console. a1 has a source that listens for data on port 44444, a channel This configuration defines a single agent named a1. # nf: A single-node Flume configuration # Name the components on this agent a1.sources = r1 a1.sinks = k1 a1.channels = c1 # Describe/configure the source a1.sources.r1.type = netcat a1.sources.r1.bind = localhost a1.sources.r1.port = 44444 # Describe the sink a1.sinks.k1.type = logger # Use a channel which buffers events in memory a1.channels.c1.type = memory a1.channels.c1.capacity = 1000 a1.channels.c1.transactionCapacity = 100 # Bind the source and sink to the channel a1.sources.r1.channels = c1 a1.sinks.k1.channel = c1 The source and sink within the given agent run asynchronously HDFS sink) or forwards it to the Flume source of the next Flume agent (next The sink removes the eventįrom the channel and puts it into an external repository like HDFS (via Flume The event until it’s consumed by a Flume sink.
