Description:
report system wide file access events
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.
