Difference between Get-WebAppPoolState & Get-WebsiteState

Question

Hello I was trying to write a 2 Powershell Script to be able to capture All AppPoolState and All WebSiteState for IIS. But I am stumped with this

[System.Collections.ArrayList]$ApplicationPoolsState = Get-WebAppPoolState | % { return @{($.itemxpath -split ("'"))[1]="$($.value)" } }

$ApplicationPoolsState.keys .NET v4.5 .NET v4.5 Classic DefaultAppPool

But

[System.Collections.ArrayList]$ApplicationSiteState = Get-WebsiteState | % { return @{($.itemxpath -split ("'"))[1]="$($.value)" } }

$ApplicationSiteState.keys

The Second one returns blank. Even Though the array is there > $ApplicationSiteState Name Value ---- ----- Default Web Site Started

What am I missing :(

Answer 1

Seems to be working for me. Please use the Code Sample tool when posting code. Otherwise the site removes underscore characters.

cls  
[System.Collections.ArrayList]$ApplicationSiteState = Get-WebsiteState | % {   
    return @{  
        ($_.itemxpath -split ("'"))[1]="$($_.value)"  
    }   
 }  
 "===========Site State ==========="  
 $ApplicationSiteState | Format-Table  
  
 [System.Collections.ArrayList]$ApplicationPoolsState = Get-WebAppPoolState | % {   
    return @{  
        ($_.itemxpath -split ("'"))[1]="$($_.value)"   
    }   
 }  
"===========Pool State ==========="   
$ApplicationPoolsState | Format-Table  

Answer 2

Hello

Thank You very much for your response

For ApplicationSiteState see the .keys is blank

While in ApplicationPoolState

My Full Code - it is forked from https://github.com/pszafer/check_iis_pool

I made necessary modification to be able to exclude few AppPool which doesn't need monitoring
I similarly trying to do it for WebSite which doesn't need monitoring

We have a problem in around line number 70

Answer 3

Appears to be related to the fact that you only have one web site, and thus one entry in the arraylist.

I played around and this appears to work. Give it a try.

 [System.Collections.ArrayList]$ApplicationSiteState = @() 
 Get-WebsiteState | % { 
     $ApplicationSiteState.add(@{($_.itemxpath -split ("'"))[1]="$($_.value)"})
 }
 "===========Site State ==========="
 $ApplicationSiteState | Format-Table
 "===========Keys ==========="
 $ApplicationSiteState.keys 
  

Answer 4

Hello

Thank You very much. Why will a single item array list not work (not sure)

With this method

[System.Collections.ArrayList]$ApplicationSiteState = @()   
    Get-WebsiteState | % {   
      $ApplicationSiteState.add(@{($_.itemxpath -split ("'"))[1]="$($_.value)"})  
    }  

It is working OK - but I am getting output of

0
1
2
Etc (count of number of website). Is it possible to stop that print ?
If there is an issue sending this count down will irate the operations team :)
