(a) The status of every dome in La Silla is monitored and is used as one of the safety parameters we include in our opening decision algorithm. Also an automatic statistics is computed after each night in order to keep track of real night length (useful for meteo technical downtime statistics) as well as the effective use of the open time. Percentages report shutter-open time in the night. Errors (in red) are noncompleted observing blocks that need to be repeated. (b) The log of every subsystem status.
