question

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

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

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 

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 :)

 $count = $ApplicationSiteState.add(@{($_.itemxpath -split ("'"))[1]="$($_.value)"})
