I want to write a puppet manifest that will first check available space in C drive if the size is exceed then it will call powershell script

Question

Senario 1 : I want to write a puppet manifest that will first check available space in C drive if the size is exceed then it will call powershell script to do the housekeeping.

How i can add condition that will check the C drive space and if the limit is exceeding then it will run below module that has contain to do the housekeeping

From below class i am able to run ps1 file but command not executing

class windows_disk_cleanup::disk { 
$powershell ='C:/Windows/System32/WindowsPowerShell/v1.0/powershell.exe'#-NoProfile -NoLogo -NonInteractive' 
    exec { 'external-code': 
      command   => "$powershell -command ('windows_disk_cleanup/cleanup.ps1')", 
      logoutput => true, } }

Scenario 2: Alternatively i am thinking, before run the script it will check the condition if condition match for e.g C dirve space usage is 75% then disk_cleanup script will copy to the target server then it will run and do the housekeeping after execution that file should be remove from the server. Below something i am trying ,

 class free_disk_space::space {
 file {'C:/disk_space':
    ensure => 'directory',
    path   => 'C:/disk_space',
  }

 file { 'C:/disk_space/disk_cleanup.ps1':
     ensure => 'present',
     path   => 'C:/disk_space/disk_cleanup.ps1',
     source => 'puppet:///modules/free_disk_space/disk_cleanup.ps1',
  }

 exec { 'deploy_disk_cleanup':
     path    => 'C:/Windows/System32/WindowsPowerShell/v1.0',
     command =>'C:/Windows/System32/WindowsPowerShell/v1.0/powershell.exe -File "C:/disk_space/disk_cleanup.ps1"',
     timeout => 0
  }
exec { 'remove_disk_cleanup':
    command     =>'C:/Windows/System32/WindowsPowerShell/v1.0/powershell.exe "Remove-item -path C:/disk_space/disk_cleanup.ps1"',
    refreshonly => true,
 }
}

I hope i am able to explain my query and what i am looking for
