For the ad hoc report or overview report the data sources are not specified and you can generate a report from an arbitrary position in the machine tree. You can specify the data types at certain positions in the template and separately set the time filter for each data type. Very often the same machines have to be similarly created in the database, so that the ad hoc report can be applied to each of these machines. You can then obtain a quick overview of the machine states.
Starting from the selected node, the ad hoc report contains all data of a branch. Given a selected root, therefore, the ad hoc report contains the entire data tree.
