Bonjour,  
 
j'ai un souci au niveau de mes graphs, toutes les données ne s'affichent pas (voir le graph de ce lien: http://forums.cacti.net/about31170.html).
 
apres quand je fais un turn off Data Source Debug Mode j'ai:
RRDTool Command:
 
/usr/bin/rrdtool graph - \

et pour le data source:

/usr/bin/rrdtool create \

Je ne vois pas pourquoi certaines données sont 'nan'.
 
merci par avance de votre aide.
