Radhakrishna, The "fileSize" attribute should be available for every flow file. Can you describe how you are finding the default set of attributes and which ones you are finding?
To test, I generated a flow file with the text "Hello" in it, then sent that to a LogAttribute processor, and got the following output: -------------------------------------------------- Standard FlowFile Attributes Key: 'entryDate' Value: 'Mon Mar 28 19:47:03 EDT 2016' Key: 'lineageStartDate' Value: 'Mon Mar 28 19:47:03 EDT 2016' Key: 'fileSize' Value: '5' FlowFile Attribute Map Content Key: 'filename' Value: 'myfile' Key: 'path' Value: './' Key: 'uuid' Value: '11964802-2c2c-4b43-8cb4-a0d724032bbf' -------------------------------------------------- The "fileSize" attribute is listed and contains the correct value of 5.
