The data taking of the different components of the Pierre Auger Observatory, i.e. the surface detectors (SD) and the fluorescence telescopes (FD) has to be supervised by a shift crew on site to guarantee a smooth operation. A monitoring tool has been developed to support the shifter in judging and supervising the status of the detector components, the electronics and the data-acquisition (DAQ). Data are collected online for this purpose in the regular measuring time as well as in dedicated modes e.g., for calibration or atmospheric surveys. While for some components like SD this information is directly collected and stored by the DAQ on the central campus, the remote four FD detector sites collect and store their data in local databases. These databases are replicated online to the central server on the campus via a wireless long distance link. A web-interface implemented on a dedicated server can dynamically generate graphs and particular developed visualisations to be accessible not only for the shifter, but also for experts remotely from anywhere in the world. This tool does also offer a unique opportunity to monitor the long term stability of some key quantities and of the data quality. The concept and its implementation with emphasis on the FD-part will be presented.
