| + | |||
| + | Le daemon peut être configuré pour modifier d'une manière dynamique les paramètres du noyau en fonction de la charge du système, en commencant avec les valeurs incluent dans le profil actif. Pour faire ceci, le daemon utilise des modules plug-ins **monitor** et des modules plug-ins **tuning**. Les plug-ins **monitor** analysent le système et fournissent les informations recoltées aux plug-ins **tuning** qui les utilisent pour appliquer des modifications dynamiques. | ||
| + | |||
| + | Les plugs-in **monitor** sont : | ||
| + | |||
| + | * **disk** - surveille le nombre d' | ||
| + | * **net** - surveille le nombre de paquets transmis par chaque interface réseau, | ||
| + | * **load** - surveille la charge de chaque CPU. | ||
| + | |||
| + | Les plug-ins **tuning** corréspondants sont : | ||
| + | |||
| + | * **disk** - définit différents paramètres de disque, par exemple le planificateur de disque ou la gestion avancée de l' | ||
| + | * **net** - configure la vitesse de l' | ||
| + | * **cpu** - définit différents paramètres des CPU par exemple le CPU governor ou la latence. | ||
