Whatbis the best way to review data regarding blended agent stats

It depends on the stats and how you want to use the data. For real-time or onscreen view in Genesys Cloud of Agent Stats use the Performance --> Agents view. For reporting, analysis, and distribution I would recommend Brightmetrics. www.brightmetrics.com as an add-on solution that is far superior than Genesys included reporting. If you don't want to use a third party like Brightmetrics, the Agent Metrics Summary and Agents Quality Summary reports can help.

To obtain agents status data, navigate to the reports tab, select new, and choose the option for agents status.
