I’ll show you how to get total elapsed time for processes in same output with using Label and Expression function of PowerShell. You can see the command below:

(Get-Process | ft Name,@{label="Elapsed Time";expression={[System.Math]::Round(((Get-Date)-$_.StartTime).TotalSeconds)}})

You can execute additional commands with Expression function in same PowerShell command.

}

This is the preview code of PoSHStats Exchange Server module.

In this example, you can’t open notepad.exe more than once. New notepad.exe processes will be killed.

$ShouldProcess = $true
While ($ShouldProcess)
{
                $Processes = Get-Process -Name Notepad -EA SilentlyContinue
                if ($Processes.Count -gt "1")
                {
                Get-Process -Name Notepad | Sort-Object StartTime | Select-Object -Skip 1 | Stop-Process
                }
}

Also it’s possible to add delay between process kills.

First, you need to install PSTools on your server. Copy psexec.exe and pskill.exe into C:\ directory.

After that you can patch servers like this:

1
2
3
4
5
6
7
8
9
10
11
$Servers = Get-Content "C:\Servers.txt"
foreach ($Server in $Servers)
{
	$PSExecPath = "C:\psexec.exe"
	$PSKillPath = "C:\pskill.exe"
	$Command1 = "C:\cp017534.exe /s"
	$Shell1 = $PSExecPath + " \\" + $Server + " " + $Command1
	cmd.exe /c $Shell1
	$Shell2 = $PSKillPath + " \\" + $Server + " PSEXESVC"
	cmd.exe /c $Shell2
}

cp017534.exe is the hp’s firmware update. It’s located on my servers C:\ directory also.

$Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
	$VMInfo = Get-VM $Server
	$VMHost = $VMInfo.VMHost
	$VMHostName = $VMHost.Name
	$VMHostGroup = $VMHost.VMHostGroup
 
	if ($VMInfo.PassThroughDisks)
	{
		$PassThroughDisk = "True"
	}
	else
	{
		$PassThroughDisk = "False"
	}
 
	if ($VMHostGroup -like "All Hosts\*")
	{
		Add-Content -Value $Server -Path C:\Servers.txt
		Add-Content -Value $VMHostName -Path C:\VMHosts.txt
		Add-Content -Value $PassThroughDisk -Path C:\PassThroughDisks.txt
	}
}

Also you can filter specific Host Groups like in this sample.

You can get ready and retry queue’s of Exchange Server with this script:

$ExchangeHost = "ExCas01"
$ExchangeServer = Get-ExchangeServer -Identity $ExchangeHost
 
# Integers
[int]$ExchangeActiveConnections = 0;
[int]$ExchangeRetryQueue = 0;
[int]$ExchangeMessageQueue = 0;
[int]$ExchangeActiveQueue = 0;
[int]$HostMessageQueue = 0;
[int]$HostRetryQueue = 0;
 
# Get Mail Queue
if ($ExchangeServer.IsHubTransportServer -eq $True)
{
	# Message Queue
	$MessageQueue = Get-Queue -Server $ExchangeHost | Where {$_.Status -eq "Ready" -and $_.MessageCount -gt "0"}
 
	# Sum Message Queue
	Foreach ($Queue in $MessageQueue)
	{
		[int]$HostMessageQueue = [int]$HostMessageQueue + [int]$Queue.MessageCount
	}
 
	# Retry Queue
	$RetryQueue = Get-Queue -Server $ExchangeHost | Where {$_.Status -eq "Retry" -and $_.MessageCount -gt "0"}
 
	# Sum Retry Queue
	Foreach ($Queue in $RetryQueue)
	{
		[int]$HostRetryQueue = [int]$HostRetryQueue + [int]$Queue.MessageCount
	}
 
	# Exchange Queue
	[int]$ExchangeRetryQueue = [int]$ExchangeRetryQueue + [int]$HostRetryQueue
	[int]$ExchangeMessageQueue = [int]$ExchangeMessageQueue + [int]$HostMessageQueue
	[int]$ExchangeActiveQueue = [int]$ExchangeActiveQueue + [int]$HostRetryQueue + [int]$HostMessageQueue
}

You can add multiple Exchange hosts to an array, it’ll just query Hub Transport servers. It only support Exchange Server 2010.

In this sample, I’ll show you how to get active Exchange Server CAS connections via PowerShell:

$ExchangeHost = "ExCas01"
$ExchangeServer = Get-ExchangeServer -Identity $ExchangeHost
 
# Get Connections
if ($ExchangeServer.IsClientAccessServer -eq $True)
{
	# OWA Connections
	$HostOWAConnections = (Get-Counter "\MSExchange OWA\Current Unique Users"  -ComputerName $ExchangeHost).CounterSamples[0].CookedValue
 
	# RPC Connections
	$HostRPCConnections = (Get-Counter "\MSExchange RpcClientAccess\User Count"  -ComputerName $ExchangeHost).CounterSamples[0].CookedValue
 
	# POP3 Connections
	$HostPOP3Connections = (Get-Counter "\MSExchangePop3(1)\Connections Current"  -ComputerName $ExchangeHost).CounterSamples[0].CookedValue
 
	# IMAP Connections
	$HostIMAPConnections = (Get-Counter "\MSExchangeImap4(1)\Current Connections"  -ComputerName $ExchangeHost).CounterSamples[0].CookedValue
 
	# Exchange Connections
	[int]$ExchangeActiveConnections = [int]$HostOWAConnections + [int]$HostRPCConnections + [int]$HostPOP3Connections + [int]$HostIMAPConnections
}

You can loop this script to get real time connection statistics.
