$report += $object

}

Did you check if Get-VM -Name APP01 returns a VM?

[ganapa2000]

LucD,

yes, App01 exists and also present in the file.

Now, after I exited the session and opened new session, I am getting the below error in the output file

"VM","ExitCode","ScriptOutput","Uid","Length"

"APP01","0","Get-WmiObject : Cannot validate argument on parameter 'ComputerName'. The argum

ent is null or empty. Supply an argument that is not null or empty and then try

the command again.

I suspect there might be something wrong in your .TXT file.

Does this produce any errors?

Get-VM -Name (Get-Content .\VM.txt)

[ganapa2000]

LucD,

I dont see any errors in the output

also attached the script for reference

[LucD]

You are using inside the code you sent to the guest OS of the VM, a variable that you defined in the calling program ($machines).

That will not work I'm afraid.

Give it a try like this

connect-viserver 10.10.10.19

$script = @'

Get-WmiObject win32_operatingsystem | %{

  $_.ConverttoDateTime($_.lastbootuptime)

}

'@

$machines = Get-Content .\CSG_VM1.txt

Invoke-VMScript -VM $machines -ScriptText $Script -GuestUser "admin" -GuestPassword "password" |

Select @{N = 'VM'; E = { $_.VM.Name } }, @{N = 'LastBootUpTime'; E = { [DateTime]$_.ScriptOutput } } |

Export-csv -NoTypeInformation -Path .\CSG_Uptime.csv

disconnect-viserver -Server * -confirm:$false

[ganapa2000]

LucD,

Perfect, that worked, one last thing, how can get the uptime in days ?

[LucD · Accepted solution]

Try like this

connect-viserver 10.10.10.19

$script = @'

Get-WmiObject win32_operatingsystem | %{

  $_.ConverttoDateTime($_.lastbootuptime)

}

'@

$machines = Get-Content .\CSG_VM1.txt

Invoke-VMScript -VM $machines -ScriptText $Script -GuestUser "admin" -GuestPassword "password" |

Select @{N='VM';E={$_.VM.Name}},

   @{N='LastBootDaysAgo';E={[math]::Round((New-TimeSpan -Start ([DateTime]$_.ScriptOutput) -End (Get-Date)).TotalDays,0)}} |

Export-csv -NoTypeInformation -Path .\CSG_Uptime.csv

disconnect-viserver -Server * -confirm:$false
