In addition to creating a new custom metric using SQL statements or by using an Insight query, Identity Governance provides you the ability to download custom metric definitions so that you can edit and import them.
To download and import custom metric definitions:
Log in as a Global or Data Administrator.
Select Configuration > Analytics and Role Mining Settings.
Select names starting with an asterisk (*).
Select Actions > Download Definitions to download custom metric definitions.
To import custom facts, select Import Custom Metrics, browse for custom metric JSON files containing exported custom metrics, select entities to import, and then click Import.
(Conditional) If there is a conflict with an existing metric, resolve the conflict by selecting Import new to create a new custom metric or select Replace Existing to replace the existing metric.
