The Global Statistics Reporting (GSR) Collector collects data for general statistics, presents historical data, reports on anomalies such as potential orphaned home folders, and catalogs managed storage movement.
As the first step in managing your existing user storage through Storage Manager, you should run the GSR Collector. Depending on the size of your network, running the GSR Collector might be resource intensive and can take some time to complete. After you run the GSR Collector the first time, you should schedule it to run at a regularly scheduled time, preferably after regular business hours.
Launch the Admin Client.
In the Main tab options, click GSR Collector.
Click Run Collector.
