Sentinella monitors your system activity and, when a condition is met, takes an action that you\'ve chosen.
Thanks to libsysactivity (http://sourceforge.net/projects/libsysactivity/) it can measure the activity of your processors, memory, network interfaces (and more) and whenever one of these conditions reaches some limit it will automatically execute an action of your choice, such as shutdown/reboot/hibernate your computer, kill a process, trigger an alarm or execute any command.
So it can, for example, turn off your computer when the network traffic falls, or reboot it when an application ends.
