I've included a sample report below that counts the active assets in each static group. You can add this report to your Lansweeper installation by following
these instructions and display its results on your dashboard with the built-in Data Report widget. You can also display it as a chart with the Chart Report widget, if you give the report a name that starts with "Chart:"
Select Top 1000000 tblAssetGroups.AssetGroup,
Count(tblAssetGroupLink.AssetID) As Count
From tblAssetCustom
Inner Join tblAssetGroupLink On tblAssetCustom.AssetID =
tblAssetGroupLink.AssetID
Inner Join tblAssetGroups On tblAssetGroups.AssetGroupID =
tblAssetGroupLink.AssetGroupID
Where tblAssetCustom.State = 1
Group By tblAssetGroups.AssetGroup
Order By tblAssetGroups.AssetGroup
