The Changes tab for AD Monitoring Configuration window provides additional options to monitor changes made to the domain.
After checking the Enable AD Changes box, the following event filters can be modified on the sub-tabs:
- Attributes
- Classes
- Context
- Host (From)
- IP Addresses (From)
- Objects

Attributes
The Attributes Tab is where monitoring can be scoped to include events with specific attributes within Active Directory. Further scoping of attributes can enable monitoring to only capture events based on the new value.
Double-click the text box beneath Name to enter the desired attribute to include or exclude. Double-click the text box beneath Value to enter the desired attribute value to reference. Choose the Operation to relate the Name and Value with. Press the Enter or Tab key to add another textbox.
NOTE: Name field must contain Active Directory attribute name.
Scoping the filter captures events when the new value matches with the supplied value. To scope the filter based on the new value of the attribute, use the Operation drop-down menu.
- AnyValue – No scoping applied for this attribute
- EmptyValue – Blank attribute values
- Equal – Attribute values that are identical to the Value field
- NotEqual – Attribute values that do not match the Value field
