@JamesE    You can handle this easily using a different set of Java Regular Expressions: .*action=(.*?) .* .*srcip=(.*?) .* .*timestamp=(.*?) .*   If it is possible that any one of these fields may be the very last field in the content line, for this to work you would need to append a blank space to the end of the content using the ReplaceText processor before sending your FlowFile to your ExtractText processor.  You need to have a blank space following each value so regex know where the value ends for each field. Your ReplaceText processor configuration would look like this: The "Replacement Value" is just a single space. Hope this helps, Matt ... View more
