Problem with Get-Service

PowerShell Help
1

i have created a function like below:
function Get-SQLServices
{

Param
(
    # Param1 help description
    [string[]]$ComputerName = $env:COMPUTERNAME
)

Get-Service -ComputerName $ComputerName | where {$_.name -like '*MSOLAP*' -or 
                                            $_.name -like '*MSSQL*' -or 
                                            $_.name -like '*SQLAgent*' -or 
                                            $_.name -like '*ReportServer*' -or 
                                            $_.name -like '*SQLBrowser*' -or 
                                            $_.name -like '*SQLPBENGINE*' -or
                                            $_.name -like '*SQLPBDMS*' -or
                                            $_.name -like '*MsDtsServer*' -or
                                            $_.name -like '*MSSQLLaunchpad*' -or
                                            $_.name -like '*SQLSERVERAGENT*' -and 
                                            $_.name -notlike '*MSSQLFDLauncher*'
                                            } | Select status, Name, DisplayName, MachineName ,DependentServices,ServicesDependedOn

}

and when i try to use below command i get error although the service exists:
Get-SQLServices -ComputerName myserver| where {$_.name -eq ‘MSOLAP$DVLP2014’} |Restart-Service
Error:
Restart-Service : Cannot find any service with service name ‘MSOLAP$DVLP2014’.
At line:1 char:86

  • … AP$DVLP2014’} |Restart-Service
  •                ~~~~~~~~~~~~~~~
    • CategoryInfo : ObjectNotFound: (MSOLAP$DVLP2014:String) [Restart-Service], ServiceCommandException

Looks like you are get a list of service from a remote computername, but you are try to restart a service on your local computer.

No, i am sending the result through the pipe-line.
it works fine if i write it like
Get-Service sql -computername myserver | Restart-Service

In your function the last thing you are doing is a select-object

...
 | Select status, Name, DisplayName, MachineName ,DependentServices,ServicesDependedOn

The result of this is a PSCustomObject being passed to the pipeline.

When you pipe that into Restart-Service it fails because it only accepts 2 variations of pipeline input.

1)

-InputObject


Specifies ServiceController objects that represent the services to restart. Enter a variable that contains the objects, or type a command or expression that gets the objects.


Type: ServiceController

Parameter Sets: InputObject

Aliases:


Required: True

Position: 0

Default value: None

Accept pipeline input: True (ByValue)

Accept wildcard characters: False

2)

-Name


Specifies the service names of the services to restart.


Type: String

Parameter Sets: Default

Aliases: ServiceName


Required: True

Position: 0

Default value: None

Accept pipeline input: True (ByPropertyName, ByValue)

Accept wildcard characters: False

As you see the -InputObject requires a “ServiceController” object, and -Name requires a String. You are passing neither a string or a ServiceController object.

If you removed the select-object at the end of your function, it would probably work just fine.

Thanks for your reply. but the point is i need to use that select.
how can i fix it by using select!

and when i do Get-Member:

Get-SQLServices | gm

it returns TypeName: Selected.System.ServiceProcess.ServiceController not PSCustomObject

Ok it’s not a PSCustomObject, but it’s still not a System.ServiceProcess.ServiceController, it’s a Selected.System.ServiceProcess.ServiceController, which is different and not what Restart-Service is expecting.

Can you not just do your select, for whatever reason you need it, after the function returns?

$services = Get-SQLServices -ComputerName server
$services | Where-Object {$_.Name -eq 'MSOLAP$DVLP2014'} | Restart-Service
$services | Select status, Name, DisplayName, MachineName ,DependentServices,ServicesDependedOn

or

Get-SQLServices -ComputerName server |
Where-Object {$_.Name -eq 'MSOLAP$DVLP2014'} |
ForEach-Object {
    $_ | Restart-Service
    $_ | Select status, Name, DisplayName, MachineName ,DependentServices,ServicesDependedOn
}

You probably need to wrap your Restart-Service in a Invoke-Command:

Invoke-Command {Restart-Service $_ } –ComputerName $ComputerName
