Peux tu essayer de le lancer en root ?

Meme chose en root :

Tu as bien la version 0.5 de python-statgrab ?

sudo apt-cache show python-statgrab | grep "Version"
Version: 0.5-0ubuntu2

from glances.

Désolé j'avais pas vu ce message, oui j'ai bien la bonne version :
Version: 0.5-0ubuntu2

from glances.

Peux tu compléter avec les informations suivantes:

Version de python: ___
à l'aide de la commande:
python -v

Version de libstatgrab: ___
à l'aide de la commande:
sudo apt-cache show libstatgrab6 | grep Version

Version de python-statgrab: ___
à l'aide de la commande:
sudo apt-cache show python-statgrab | grep « Version »

from glances.

sudo python -V
Python 2.7.1+

sudo apt-cache show libstatgrab6 | grep Version
Version: 0.17-0ubuntu1

sudo apt-cache show python-statgrab | grep Version
Version: 0.5-0ubuntu2

from glances.

On dirait que sur ton système, la directive diskio de libstatgraph retourne une erreur.

Peux tu me confirmer cela en saisissant les commandes suivantes (je te met ce qu'elles retournent sur mon système):

C'est dingue car cela marche sur ma VM en 11.04...

Essaye cela (après je sèche...):

sudo apt-get update
sudo apt-get install pkg-config build-essential autoconf automake python libstatgrab-dev python-all-dev
sudo apt-get remove python-statgrab
wget http://ftp.uk.i-scream.org/sites/ftp.i-scream.org/pub/i-scream/pystatgrab/pystatgrab-0.5.tar.gz
tar zxvf pystatgrab-0.5.tar.gz
cd pystatgrab-0.5/
./setup.py build
sudo ./setup.py install

from glances.

Hummmm, tjours pareil.
J'ai l'impression que c'est space sur cette machine, c'est un vps xen :

apt etc.... puis :

Le problème semble donc venir de la librairie libstatgrab...

La directive sg_get_disk_io_stats_diff() va lire les informations dans le fichier /proc/diskstats. Peux tu me faire un copier coller ?

Dans tous les cas, je pense qu'il faut remonter le pb au niveau du développeur de libstatgrab: http://freecode.com/projects/libstatgrab

cat /proc/diskstats

Ok, tant pis, en tout cas c'est un beau projet, je l'utilise sur des machines plus standard ;)
