Watchdog
A watchdog is a system component that monitors certain functions of a sys-
tem at certain time intervals. If an error or a deviation in relation to previ-
ously defined limits is recognized, appropriate measures for solving the
problem are introduced. The main application is monitoring of system fail-
ures recognized by the watchdog when the system no longer reacts to regular
queries by the watchdog.
