I’ve seen this code:

$values = new-object ‘object[,]’ 5,2
Can you expound on that?
The author fills the array.
$k = 0
foreach ($j in $exchangeserverlist)
{
$perf = New-Object System.Diagnostics.PerformanceCounter($perfobj1,
$counter1, $instance1, $j.Name)
$values[$k,0] = $j.Name
$values[$k,1] = $perf.RawValue
$k = $k + 1
}
Now, how do you sort the array based on the performance data in the second
column?
I’m guessing there’s a more “powershell” was of doing what’s needed rather
than resorting to arrays. E.g.,
$p = get-process
$p | sort-object ws
How would you create a collection of custom objects. Each custom object
would have two custom properties “exchangeserver” and “perfdata”.
{create the custom collection – somehow}
$co | sort-object perf

Here is my response:

Hal taught me a cool way to create custom objects that he learned from PowerShell MVP Brandon Shell. Here’s a link to the post.

Here’s the code you may want to try…

$k = 0 $co = $(foreach ($j in $exchangeserverlist) {

$values = "" | Select-Object server,perf # this is where your custom object is created

$perf = New-Object System.Diagnostics.PerformanceCounter($perfobj1,

$counter1, $instance1, $j.Name)

$values

.server =

$

j.Name # populating custom object

$values

.perf =

$

perf.RawValue # populating custom object

$k = $k + 1

$values

})

$co | sort-object perf

Jaykul on IRC helped me figure out that you need to create the custom object in the loop. I tried to do it outside the loop and it didn’t work the way I wanted it to.

Or you could use this method that Hal suggested

$k = 0 $co = @() # this creates an empty array

foreach ($j in $exchangeserverlist) {

$values = "" | Select-Object server,perf # this is where your custom object is created

$perf = New-Object System.Diagnostics.PerformanceCounter($perfobj1,

$counter1, $instance1, $j.Name)

$values

.server =

$

j.Name # populating custom object

$values

.perf =

$

perf.RawValue # populating custom object

$k = $k + 1
$co += $values # this populates the array

})

$co | sort-object perf
