About this task

Reducing the record age can prevent analyzing stale data, reduce unnecessary processing overhead, and focus the metric on more recent activity. Increasing the record age includes analysis of older records.

Procedure

Navigate to All > System Properties > All Properties.
In the Name column, use the search field to locate the sn_ai_security.analyzer_max_record_age_hours system property.
Open the record.
The default value is 4, which limits processing of AI asset invocation records to those records 4 hours old or newer.
In the Value field, enter the age (in hours) of records you want to process for AI asset security metrics.
Select Update.
