Function Get-ObjectSchemaAsHash { <# .SYNOPSIS Gets the schema of the object as hash table with column-names and their type (strin, boolean, dynamic, etc.) .DESCRIPTION Used to validate the data structure - and give insight of any potential data manipulation Support to return in both LogAnalytics table-format and DCR-format .PARAMETER Data Object to modify .PARAMETER ReturnType Object to modify .INPUTS None. You cannot pipe objects .OUTPUTS Updated object with CollectionTime .EXAMPLE $verbose = $true $TenantId = "xxxxx" $LogIngestAppId = "xxxxx" $LogIngestAppSecret = "xxxxx" $TableName = 'InvClientComputerOSInfoV2' # must not contain _CL $DcrName = "dcr-" + $AzDcrPrefixClient + "-" + $TableName + "_CL" $DceName = "dce-log-platform-management-client-demo1-p" $LogAnalyticsWorkspaceResourceId = "/subscriptions/xxxxxx/resourceGroups/rg-logworkspaces/providers/Microsoft.OperationalInsights/workspaces/log-platform-management-client-demo1-p" $AzDcrPrefixClient = "clt1" $AzDcrSetLogIngestApiAppPermissionsDcrLevel = $false $AzDcrLogIngestServicePrincipalObjectId = "xxxxxx" #------------------------------------------------------------------------------------------- # Collecting data (in) #------------------------------------------------------------------------------------------- Write-Output "" Write-Output "Collecting OS information ...
