@Hadoop User The processor components all have tags associated to them and the associated documentation for each processor component is also embedded in the application under "help" (found in upper right corner menu). If you drag the add "Processor" icon to your canvas you will be presented with aadd processor UI. In the upper right corner is a filter box. Typing "syslog" or "hdfs" will reduce the list to those processors that share those tags. Clicking on a processor will display a brief description of the processor in the same UI near the bottom. Details documentation can be found in help or by right clicking on a processor already added to the canvas and selecting"usage" form the context menu that appears. As far as what processor you want to use depends on your complete use case. First you need to determine ho you are going to ingest this syslog data (ListenSyslog) processor is an option. As far as writing to HDFS, the PutHDFS processor is the likely choice. There are many processors available for manipulating NiFi FlowFile content between ingestion and writing out the data to a destination. Thanks, Matt ... View more
