Thanks for the script!
How can I export the result to a csv-fil? I would like to shedule the script to run every 10 min and collect the data.

try this it should work:
Function New-Array {,$args}
$Report = new-array

$CASServers = Get-ClientAccessServer | select name

Foreach ($srv in $CASServers){
$RPC = Get-Counter “\MSExchange RpcClientAccess\User Count” -ComputerName $srv.name
$OWA = Get-Counter “\MSExchange OWA\Current Unique Users” -ComputerName $srv.name
$ASY = Get-Counter “\MSExchange ActiveSync\Current Requests” -ComputerName $srv.name
$cas = New-Object System.Object
$cas | Add-Member -type NoteProperty -name Server -value $($srv.name)
$cas | Add-Member -type NoteProperty -name RPCClientAccess -value $($RPC.CounterSamples[0].CookedValue)
$cas | Add-Member -type NoteProperty -name OWA -value $($OWA.CounterSamples[0].CookedValue)
$cas | Add-Member -type NoteProperty -name ActiveSync -value $($ASY.CounterSamples[0].CookedValue)

$Report += $cas
}

I am trying to add ActiveSync to this one….

$CASServers = Get-ClientAccessServer | select name

Foreach ($srv in $CASServers){
$RPC = Get-Counter “\MSExchange RpcClientAccess\User Count” -ComputerName $srv.name
$OWA = Get-Counter “\MSExchange OWA\Current Unique Users” -ComputerName $srv.name
$ASY = Get-Counter “\MSExchange ActiveSync\Current Requests” -ComputerName $srv.name
New-Object PSObject -Property @{
Server = $srv.name
“RPC Client Access” = $RPC.CounterSamples[0].CookedValue
“Outlook Web App” = $OWA.CounterSamples[0].CookedValue
“ActiveSync” = $ASY.CounterSamples[0].CookedValue
}
}

It works well except the part that it gives me activesync first and then server name.

Carl,
Your script worked a little better by specifing the actual servers. I’m guessing my 2007 cas servers were causing the issue.

I will try again tomorrow. It did however return our legacy 2007 cas servers when I ran the Get-ClientAccessServer | select name
command. maybe the full script doesn’t like the 07 servers.

This command worked fine when i used the casservername of the cas server i was logged into:
Get-Counter “\MSExchange RpcClientAccess\User Count” -ComputerName casservername

I will try tomorrow with a different cas server which I’m not logged into.

You should get your cas server names in variable $CASServers
$CASServers = Get-ClientAccessServer | select name
then run $CASServers you should get list of your cas servers.
try to run
Get-Counter “\MSExchange RpcClientAccess\User Count” -ComputerName casservername
where casservername use cas server name where you are logged, do you get any value ?
next run again Get-Counter “\MSExchange RpcClientAccess\User Count” -ComputerName casservername
but use as casservername other cas server name where you are now not logged, will you get any value ?

Both those commands worked fine and I subbed the -ComputerName actualservername.
I’m not a scripting guru so do I need to sub my actual cas server host names in the script above?

Hi
I’ve checked this script with Exchange 2010 SP2 RU5v2 and it works, but I don’t use HLB.
In your environment with HLB can you try to run:
Get-ClientAccessServer | select name
Will you get all yours CAS servers ?
next try to run:
Get-Counter “\MSExchange RpcClientAccess\User Count” -ComputerName casservername
Did you get any value or just error ?
maybe you don’t have needed rights or WinRM enabled ?
Maybe HLB is the problem, but I can’t check that.

Hi
To identify which users are connected to which CAS server you can try to use Get-LogonStatistics
You will get information about ClientName – CAS server when you specirfy ApplicationId like Client=MSExchangeRPC or ApplicationId like Client=OWA.
Then you need to add LogonTime and you will get what you want.
