Hi, @shockoMS
Thank you for posting in Microsoft Q&A forum.
The view v_GS_SYSTEM_CONSOLE_USAGE_MAXGROUP have the same info to WMI class SMS_SystemConsoleUsage.
The difference is that the info in v_GS_SYSTEM_CONSOLE_USAGE_MAXGROUP is collected by hardware inventory, and the schedule for hardware inventory is 7 days once by default. So this could be date from a few days ago, it's not very accurate.
The data in WMI class SMS_SystemConsoleUsage is more real-time and accurate.
