“Conky est un moniteur système pour le système de fenêtre X Window s'affichant en arrière-plan sur le bureau. Il est compatible avec les systèmes GNU/Linux et BSD. Conky est capable de surveiller quasiment toutes les variables du système : processeur, mémoire, swap, espace disque, température(s), upload, download, messages du système, et beaucoup d'autres. Il est extrêmement puissant et configurable, de par le fait qu'il soit géré par ses propres scripts voire par des scripts en Lua, cela requiert quand même un certain apprentissage et un minimum de temps à consacrer.” [cf Wikipedia]
