 Posted: Wed Oct 08, 2008 12:51 am Post subject: [SOLVED] Funky /proc/*/stat output |
 |
|
For whatever reason I can't get more helpful information from /proc/*/stat. Instead of showing up with field names it's just showing up as the appname (argv[0]), the process state, plus a series of not-so-helpful integers without any sort of explanation.
Can anyone explain this phenomenon?
My info --

The only thing I can say with some sense of clarity, is -- is the CPU mask set the 5 digit from the end in the .../stat output, e.g.
17 0 (<-- this one) 0 0 0 0 0
I really would like to know why it's so different for me though...

Pretty sure that's just what /proc/*/stat looks like.
Sure you weren't thinking of /proc/*/status instead? |

Ah.... I misread the webpages.
There's a top level /proc/stat file which aggregates the statistics and data for /proc/*/stat. That's what I was looking for... |
