Filter rules:
The priority for applying filters is the following: when you apply a filter, all filters that are set below it are also applied, and the filters that are set above it, if any, are not applied.
The conditions for applying the filter criteria are the following: when you set two or more filter criteria of the same type, the condition is logical OR. When you set filter criteria of a different type, the condition is logical AND.
ExampleIf you set the following filters by content:
Severity equals WARNING
Severity equals ERROR
Category contains /System/
the system will display logs and traces with category /System/ and severity levels WARNING and ERROR.
End of the example.
