Monitoring data is received from a remote device and represents a current status value of a monitored condition at the remote device. The monitored condition is characterized by a current state that can be any one of a number of possible states. A determination is made as to whether the current status value of the monitored condition as indicated by the received data satisfies a hysteresis criterion associated with the current state of the monitored condition. If the current status value of the monitored condition satisfies the hysteresis criterion, then a determination is made as to whether the hysteresis criterion has been continuously satisfied for a specified persistence period. If the hysteresis criterion has been continuously satisfied for the specified persistence period, then the current state of the monitored condition is changed to reflect the current status value of the monitored condition, and the changed current state is recorded. |
