WSUS Server Reporting: Query TargetComputers for LastReportingStatus

Question

Hi,
I'm having quite a difficult time in finding a way how to query multiple WSUS servers for the last report time of all TargetComputers.  I would like to query all targetcomputers on our Upstreamserver (master, the others are in replica mode) by FullDomainName.
That way I could check every client for it's site, next connect to the connect to the correct wsus server and query for the lastreport time for that client.(we have a site code in the computer names, so starting with 0 = site A, starting with 2 = site B,..)
In short, I want to query every targetcomputer there is to find for each WSUS server (3 servers) and if there is a lastreport time longer than 30 days, I want to query the other WSUS servers to check if maybe a last report date over their is more recent.
 Also, I should make my query so that when I loop through the array, I first do a check of the FullDomainName because based on it, I can connect to the correct "local wsus server" to do the check for last report time.
I have this code already, can anyone please point me in the right direction for this?
Any help is very much appreciated!
$attachments = "xxxxxxxxxxxxx","xxxxxxxxxxxxx","xxxxxxxxxxxxxxxx"
$time = (get-date).adddays(-30)
$Computername = "SERVER_A"
$UseSSL = $False
$Port = 80
[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | out-null
$Wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($Computername,$UseSSL,$Port)
$wsus.GetComputerTargets() | ?{$_.LastReportedStatusTime -lt $time -and $_.RequestedTargetGroupName -ne "Servers" -and $_.RequestedTargetGroupName -ne "Labo"} | Select FullDomainName, LastReportedStatusTime | export-csv "xxxxxxxxxxxxxx" -NoTypeInformation
$Computername = "SERVER_B"
[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | out-null
$Wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($Computername,$UseSSL,$Port)
$wsus.GetComputerTargets() | ?{$_.LastReportedStatusTime -lt $time -and $_.RequestedTargetGroupName -ne "Servers" -and $_.RequestedTargetGroupName -ne "Labo"} | Select FullDomainName, LastReportedStatusTime | export-csv "xxxxxxxxxxxxxxx" -NoTypeInformation
$Computername = "SERVER_C"

This is closer to how to do it and is easier to manage.
function Get-LateReporting{
Param(
[Parameter(
Mandatory=$true,
ValueFromPipeline=$true
)]$server
Begin{
[void][reflection.assembly]::LoadWithPartialName('Microsoft.UpdateServices.Administration')
Process{
$wsus=[Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($server,$false,80)
$wsus.GetComputerTargets() |
Where-Object{
$_.LastReportedStatusTime -lt ([datetime]::Today.AddDays(-30))
-and $_.RequestedTargetGroupName -ne "Servers"
-and $_.RequestedTargetGroupName -ne "Labo"
'servera','serverb','serverc'|
Get-LateReporting |
Select-Object FullDomainName, LastReportedStatusTime |
Export-Csv latereports.csv -NoTypeInformation
Send-MailMessage -Attachments latereports.csv -From zzzzz -To yyyyyyy -SmtpServer exchange -Priority High -Subject "WSUS Client Reportings"
You can group the results to select the newest one.
¯\_(ツ)_/¯
