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.
- In the Rule section, click Browse.
- In the Select rule window, open the Search By Counter tab; from the Performance object list, choose SQLSERVER : Database : DB Log File and click Search.
- Choose the Collect DB Log File Free Space (%) rule in the list of search results and click OK.
