All,

I have the following code I am having trouble with.
I would like it to check to see if a service call "AVSMPROXYSVC" is running and if not start the process. I would also like to write if the service is running or service is not running for each server in a list.

I need some help to get this all straight.

Thank you for your help,
Rob


$servers = Get-Content -Path C:\Load_Stuff\MonitoringScripts\Env2_TS_Servers.txt
ForEach ($server in $servers) {Get-service -ComputerName $server -Name avsmproxysvc }
if ($check -eq $null) {
Write-Host "Process is not running on $server"
Start-Service $server -Name avsmproxysvc
}
else {
Write-Host "Process is running"
}

While get-service will work on remote systems (and accepts a -ComputerName parameter to specify which one), the other *Service cmdlets only work on the local system.

To control services on remote systems, you can use invoke-command to run the commands on the remote system if you have remoting enabled, or use WMI (win32_service), or the start() and stop() methods of the service objects returned by get-service.

mjolinor,

Thanks for the help...again.

If I understand you correct...could I use something like this to call and start the service?

(gwmi -computername $server -class win32_service | Where-Object { $_.Name
-eq “$AVSM” }).startservice()

If so....could I just drop it into the script as such?

$servers = Get-Content -Path C:\Load_Stuff\MonitoringScripts\Env2_TS_Servers.txt
ForEach ($server in $servers) {Get-service -ComputerName $server -Name avsmproxysvc }
if ($check -eq $null) {
Write-Host "Process is not running on $server"
(gwmi -computername $server -class win32_service | Where-Object { $_.Name
-eq “$avsmproxysvc ” }).startservice()
}
else {
Write-Host "Process is running"
}

I think WMI methods can be used here but with PowerShell v2 we can always use the Set-Service cmdlet to start,stop,pause a service and even change the startup type of a service on a remote system.

An Example
# Ensures that the Service is started
Get-Service -Name bits -ComputerName localhost | Set-Service -Status Running -PassThru

You can try this and let the community know if it worked for you 🙂

Regads,
Dexter

I'd start with something more like this:

foreach ($server in $serverList)
{
$services = @(Get-Service -ComputerName $server -Name $serviceName)

foreach ($Service in $Services)
{
switch ($service.status)
{

'Running' {"Service {0} is running on {1}" -f $Service.Name,$server}

'Stopped' {
"Service {0} is not running on {1} - restarted" -f $Service.Name,$server
$Service.Start()
}

'Paused' {"Service {0} is paused on {1}" -f $Service.Name,$server}

'StartPending' {"Service {0} is pending Start on {1}" -f $Service.Name,$server}

'StopPending' {"Service {0} is pending Stop on {1}" -f $Service.Name,$server}

'PausePending' {"Service {0} is pending Pause on {1}" -f $Service.Name,$server}

'ContinuePending' {"Service {0} is pending Continue on {1}" -f $Service.Name,$server}

Default {"Unrecognized status {0} for {1} on {2}" -f $Service.Status,$Service.Name,$Server}
}
}
}

Then you have the option of using wildards in the service name, and it will deal with multiple services being returned by get-service, and you can easily add code to the switch script blocks to handle other possible states the service may be in other than "Running" or "Stopped".
