The Surface Array Detector of the Pierre Auger Observatory consists of about 1600 water Cherenkov detectors. The operation of each station is continuosly monitored with respect to its individual components like batteries and solar panels, aiming at the diagnosis and the anticipation of failures. In addition, the evolution with time of the response and of the trigger rate of each station is recorded. The behavior of the earliest deployed stations is used to predict the future performance of the full array.
