@MahipalRathore    The bulletin is not going to include anything more than what would be found in the nifi-app.log.  The Bulletin if produced as a result of some failure while processing a FlowFile, will have details about the FlowFiles assigned UUID and filename as well as it size relative to content claim in which the FlowFiles content can be found.  You could the use NiFi data provenance to obtain details on the FlowFile including all its FlowFile attributes.  Some bulletins are for exceptions that occur unrelated to a FlowFile directly and thus will contain no FlowFile info.  But if a FlowFile is routed to failure as a result of for example an exception thrown by the putHDFS processor, details on that FlowFile record should be included in the bulletin. Note: If the bulletin is being produced by a processor that creates a FlowFile, no FlowFile will have been created, so there is no FlowFile created from which to get FlowFile details.
