I'm running Usage_metering reports but they are still showing old hubs that haven't existed for many months.
The hub is dismissed however is still present in the CM_COMPUTER_SYSTEMS
Release : 8.51 / 9.x.x
Component : UIM - USAGE_METERING/BILLING
The dismissed hubs that are are still showing in the reports may still be in the CM_COMPUTER_SYSTEM table.
If they the unwanted devices are still visible in the UIM inventory delete the devices following the Remove Devices in USM procedure.
The report stays the same for the current month and then changes when the next month starts.
If you for example have removed a device from inventory in December then you may need to wait January to see this reflected in the reports. This would also explain why may still see some servers that have been removed from inventory in the current report.
