fatrace binary package in Ubuntu Xenial amd64

 fatrace reports file access events from all running processes.
 Its main purpose is to find processes which keep waking up the disk
 unnecessarily and thus prevent some power saving.
 .
 This package also contains a "power-usage-report" tool, which uses
 fatrace and powertop to build a textual report from one minute of
 measuring power usage and file accesses. This does not take any
 arguments or requires any interactivity, so is very simple to use and
 serves as a starting point for bug reports or optimizing a particular
 installation.
