  1. Both JSON and CSV reports device.model are blank reports for lba-histogram, latency-histogram and fs statistics are all missing the device.model device.id device.model device.name device.size rangeBegin rangeEnd read write discard total

  1. When reporting any data in CSV, please add units where possible to improve the customer experience for example device.id | device.model | device.name | device.size (sectors) | rangeBegin (ns) | rangeEnd (ns) | read (count) | write (count) | discard | total
