The Adaptive Optics Facility (AOF) started regular operations at the Very Large Telescope (VLT/ESO) in 2016 on the Unit Telescope 4 (UT4). We have now gathered several years of AO telemetry data for the following modules: GALACSI, GRAAL, the 4LGSF and the DSM. I will present here the tool and strategy implemented for monitoring these modules, their performance since 2021, and how this regular monitoring is helping with operations and maintenance activities.
