Hi Alberto. Last week, we merged the "User Guide" section into the "DataMiner Overview" section. As to folders, everything is now under the "/dataminer/" folder. Basically, the "basic functionality" folder has now become the "operator guide", and the "advanced functionality" has now become the "administrator guide". However, note that a lot of other, additional restructuring has been done as well.

The alarm filter page you gave as an example can now be found here: https://docs.dataminer.services/dataminer/Operator_guide/Alarms/About_alarms/Alarm_filters.html
