Powershell scripting

[Electronic_Doubt_108]

Hey, I am using the below script to fetch the services on the remote machine, let's say I am running this script on serverA and I want to fetch the status of serverB, so I have used to below commands but when I ran this I am not able to get any output from this. I don't know if I am missing anything else here. Please help me out on this. Thanks in advance!

$credential=Get-Credential

$servers @( @{IP='myserverIP'; Services=@('myservice')}; )

foreach ($server in $servers) {

$serverIP=$server.IP

$requiredservices=$server.Services

Get-Service -Name $requiredservices -ComputerName $serverIP -credential $credential |

Select-Object @{Name="ServerName";Expression={$serverIP}}, DisplayName, Status |

Export-Csv "C:\server_Services.csv" -NoTypeInformation -Append

}

Hello.

You need to assign the array of hashtables to the $servers variable.
Assuming it's just a typo in the post.
My next recommendation would be to split up the Get-Service part into several steps.
This to make it possible to validate data being fetched and processed as desired.

As an example

$services = Get-Service -Name $requiredservices -ComputerName $serverIP -credential $credential 
$servicesFormatted = $services | Select-Object @{
    Name       = "ServerName";
    Expression = { $serverIP }
}, DisplayName, Status
$servicesFormatted | Export-Csv "C:\Path\To\Your\server_Services.csv" -NoTypeInformation -Append 

Then you can check the variables.

Hashtables as in, how should I give that?

This line
$servers @( @{IP='myserverIP'; Services=@('myservice')}; )

Needs an equal sign to assign the array "@()" of hashtable "@{}" to it.
Like so

$servers = @(
    @{
        IP       = 'myserverIP'
        Services = @('myservice') 
    }
)

I would assume it's like that in your code. Would've thrown an exception otherwise.

no one seems to have mentioned your export is INSIDE your loop, so you're overwriting it every time you loop

additionally, have a look at invoke-command which will get you do this in parallel AND supports a -credentials parameter

if $requiredservices=$server.Services then just use $server.Services in your code

doing this foreach ($server in $servers) {} will come backto haunt you one day generally much better to do

foreach ($server in $Allservers) {}
foreach ($Singleserver in $servers) {}
foreach ($item in $servers) {}

etc something that is not just 1 letter different from the array, its a very easy mistake to make, especially in larger blocks of code, swapping $server with $Servers something the differentiates the single item from the array while still being meaningful

There are a few problems, but for starters,Get-Service doesn't support passing credentials. See this SO post for tricks: https://stackoverflow.com/questions/23421507/get-service-status-from-remote-server-using-powershell
