Add a field aging rule for entity inventory fields
Field aging deletes or deprioritizes a specific field within an inventory after a set period of time. You can create rules to modify the retention period for particular fields within an inventory. To add a field aging rule, complete the following steps:
-
Select Configure and then All configurations.
-
In the Exposure analytics section, select Inventory management and then Retention rules.
-
In the Field aging section, select Add field aging rule.
- Using the drop-down list, select an inventory.
- Select the field name you want to modify the retention period for.
- Select the action you want to perform when the entity reaches the retention period.
- Select Clear field to delete the field value after the entity reaches the retention period.
- Select Reduce priority to allow other sources to overwrite the field value after the entity reaches the retention period.
- Enter a retention period for Last seen over.
- Select Save.
-
Activate the retention by changing the Status to On.
After you add a field aging rule, you can edit the retention period again by selecting the settings icon ( ) for that rule, and you can remove the rule entirely by selecting the trash can icon.
