Hello- Wondering if there is a way in GD.CN to see when and who deleted a given insight?

Check the logs from metadata-api containers and look for log records with

method="DELETE"

and matching

uri="https://{organizationHostname}/api/v1/entities/workspaces/{workspaceId}/metrics/{objectId}

There are additional data in these records, namely

userId

and

remote

(ip address).

Thank you Robert!
