Global Exchange 2010 Mail Flow

So, I got it in my head that it might be nice to have a script in my pocket to monitor the Exchange 2010 Mail Flow speeds.  I used to have a similar script that worked with the Exchange 2007 systems that I maintain, but with the extensions of the PowerShell Snap-ins within Exchange 2010 and my better knowledge of PowerShell as a whole, I thought that I could write a better one.  So here it is scratched up quick and fresh and ready to share…

Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010 -ErrorAction SilentlyContinue

$Servers = Get-ExchangeServer | Where-Object { $_.IsE14OrLater -and $_.IsMailboxServer }
$TestPairs = @()
ForEach ( $SourceServer in $Servers )
{
    ForEach ( $TargetServer in $Servers )
    {
        $TestPair = New-Object -TypeName PSObject -Property @{ SourceServer = $SourceServer.Name; TargetServer = $TargetServer.Name }
        $TestPairs += $TestPair
    }
}
$ResultSet = @()
ForEach ( $TestPair in $TestPairs )
{
    $ResultsObject = Test-Mailflow -Identity $TestPair.SourceServer -TargetMailboxServer $TestPair.TargetServer -ErrorAction SilentlyContinue -WarningAction SilentlyContinue
    if ( $ResultsObject )
    {
        $ResultsObject | Add-Member -MemberType NoteProperty -Name SourceServer -Value $TestPair.SourceServer
        $ResultsObject | Add-Member -MemberType NoteProperty -Name TargetServer -Value $TestPair.TargetServer
        $ResultSet += $ResultsObject
    }
}
$ResultSet | Format-Table SourceServer, TargetServer, TestMailflowResult, MessageLatencyTime
