Monitor del sistema para la barra Gnome

Syspeek es una útil aplicación para aquellos que nos gusta monitorear el uso del sistema. Es práctico y diminuto. Se guarda en la barra superior. Cuando el uso de CPU roza el 100% el ícono se pone rojo. Además, con un simple click podremos ver el uso de memoria, disco y red.


La aplicación está disponible para los usuarios de Ubuntu 11.04. Para instalarlo, basta con abrir una consola y tipear:

    sudo add-apt-repository ppa:vicox/syspeek
    sudo apt-get update && sudo apt-get install syspeek
