Is there a way of accessing performance objects ?

Is there a way to access performance counter objects in PowerShell ?

I wish to access

MSExchange Transport Server SMTP Send : Messages Sent Total
MSExchange Transport Server SMTP Receive : Messages Received Total

Which is pretty obvious what they contain (Exchange 2007).

I have a scheduled PowerShell script that runs twice a day that e-mails
interesting Exchange statistics to the Admins to confirm Exchange is all
working and happy. Just adding these two values would be useful.

Is there a way of accessing performance objects ?

There is an example of accessing performance counters here

How do I access (or display their names) the individual items of this object?

How do I access (or display their names) the individual items of this object?

Doing this clearly gets the right object:-

new-object
System.Diagnostics.PerformanceCounterCategory("MSExchangeTransport
SmtpReceive") | fl

and outputs:-

CategoryName : MSExchangeTransport SmtpReceive
CategoryHelp : Performance counters for Edge SmtpReceive Component
CategoryType : MultiInstance
MachineName  : .


How can I find the items names? and then select them ?

If you want to see the counters for a category with a single instance you can

If you want to see the counters for a category with a single instance you can
do it like this

$mem = New-Object System.Diagnostics.PerformanceCounterCategory("Memory")
$mem.GetCounters() | Select CounterName

If there are multiple instances of a category try this

$proc = New-Object System.Diagnostics.PerformanceCounterCategory("Processor")
$proc.GetCounters(0) | Select CounterName

Replace the 0 with whatever instance you want to work with

Is there a way of accessing performance objects ?

Thanks for the help, this is what I ended up with:-

$c1 = new-object System.Diagnostics.PerformanceCounter("MSExchangeTransport
SmtpReceive","Messages Received Total","from POP3 forwarder")
$c2 = new-object System.Diagnostics.PerformanceCounter("MSExchangeTransport
SmtpSend","Messages Sent Total","to internet")
$c3 = new-object System.Diagnostics.PerformanceCounter("MSExchangeTransport
SmtpReceive","Bytes Received Total","from POP3 forwarder")
$c4 = new-object System.Diagnostics.PerformanceCounter("MSExchangeTransport
SmtpReceive","Message Bytes Received Total","from POP3 forwarder")
$c5 = new-object System.Diagnostics.PerformanceCounter("MSExchangeTransport
SmtpSend","Message Bytes Sent Total","to internet")
$c1, $c2, $c3, $c4, $c5 | ft CounterName, RawValue -Autosize

Works fine, though I assume someone will be along in a minute with something
shorter and more elegant.

I am having issues with the System Up Time counter in that it doesn't change.
$a = new-object System.Diagnostics.PerformanceCounter("System","System Up
Time")
$a.RawValue

Produces a static value ?
