Package request: fatrace #813

Closed TomParis01 closed 6 years ago

TomParis01 commented 6 years ago

Package: fatrace Link: https://launchpad.net/fatrace License: GNU GPL v3 Latest release: 2016-04-25 My Platform: QNAP TS-251 (Intel x86-64) Testing: I got the binary running with no problem at all on my TS-251. Can obviously only confirm for my system. Killer features:

This little tool combines the power of iotop with the knowledge which files are actually accessed. Great tool to find out which process opens / writes / closes which file exactly.

Even greater tool to find out which process prevents the HDD from spinning down and because of which file

  1. I strongly recommend to use Entware-3x, not Entware-ng on your TS-251
  2. fatrace was added to Entware-3x and will be soon in binary repo. https://github.com/Entware-for-kernel-3x/rtndev-3x/tree/master/fatrace
  3. fatrace requires kernel support. It does not run even on lede router with 4.9 kernel. It runs on qnap. I do not think we will add fatrace to Entware-ng because it is used mainly for routers.

Here is ftrace output from armv7 qnap nas
