The AppDog Software is a background service which supervises processes choosen by the user. One of the key-features is the customization though user, who can set and determine the time intervals of checking the applications, the maximum number of process restarts and which actions are supposed to carried out at failure. The time of intervall ranges from milliseconds to hours. By excellent embedding of all QUANCOM-Watchdogboards it is possible to restart the system by one of our Watchdogboards.
