End user use ArcGIS Enterprise 10.9.1. It was published map service with referenced group layers from ArcGIS Pro 3.0.
When system analyst analyze logs from ArcGIS Server Manager, there is a lot of those warnings referring group layers. There is no error, it is only warning. If you have bunch of those group layers in every service, you get extensive log file. You need to scroll down a lot through those layers. Workflow as this it is not efficient when analyzing and trying to find out issues in ArcGIS Enterprise.
Please add option to exempt those group layers warnings from ArcGIS Server Manager log files.
