Next, you need to choose a collection rule.
When you choose a collection rule, make sure that it correlates with objects included in the report scope. Every rule targets a particular class of objects. Objects included in the report scope must belong to a class that is targeted by the rule. If the scope includes a group of objects, this group must contain objects belonging to the class that is targeted by the rule.
In our example, we need to choose a rule that collects the amount of free space left for objects of the SQL DB Log File class.
