Multi instanced datasource listing Custom Customer Datasources | Archive

Hello, We needed a datasource to show custom datasources named Mon_[CustomerName]* from all our customers in a datasource. This to be able to show big numbers on each customers dashboard and also a summary on our Sales Dashboard. It is important to know that this datasource calculates from every customer so be careful which server you appy this to. Best is to have an internal server of your own. First i created the datasource and made it a multi instance datasource with Active Discovery. Below is the script fetching our customers names from device groups. Please notice that we've got all our customers inside a group called customers. We search inside that group by telling Powershell to look inside that group by its DeviceGroup ID.
