Hi Peter, I think this depends on where this data is stored. If this data is avaiable as metrics record by Nifi, then a reporting task would be the best way forward. However if this is data that is recorded in your FlowFiles as part of your flow then I think you're looking at either collecting in a KeyValue store of sorts and exposing it via a Web Server pattern or forwarding the metrics contained in the FlowFIle via a message bus, database or flow file reciever of some description.
As for displaying your metrics there are a lot of options out there that can recieve and processes data in various forms and it really depends on what is the best fit for your orginisation. Personaly I would work out how and what you use display the data and from there use that to influence how you export it out from Nifi.
