Loop through servers and check services status

[Olaf]

aristosv,
Welcome back to the forum. … long time no see.

@aristosv

So I thought I would first define which services I want to check for each server.

Why do you use if statements for that? … and BTW:

@aristosv

if ($servername = 'server1')

In PowerShell the equal sign (=) is the assignment operator. If you want to check for equality you should use -eq.

@aristosv

I then realized I will have to create a function for each server I want to check.

Why do you think you need a function? … and BTW: Set-Service is used to change the settings of a given service - not to start or restart it. Therefor you should use Start-Service or Restart-Service.

@aristosv

How can I create a single function that will go through each server and check it’s corresponding services?

I’d recommend to save the needed information in a structured way - for example a CSV file. Thhen you can iterate with a nested loop of the servers and for each server over the services.

In general: what you’re asking for is a very common and simple task what has been asked a lot of times and already answered a lot of time. You don’t have to re-invent the wheel again. Use your prefered internet search engine to search for examples you can adapt to your particular needs. You will find some even here on PowerShell.org.

Here you have some examples:

Unable to get the Output of Hashtable in Table format

Anudeep, Welcome to the forum. I’d use a [PSCustomObject] instead of a hashtable in such a case. It’s even easier to read and maintain. param( [string[]]$computername ) foreach ($computer in $computername) { $filebeat_status_before = Get-Service -Name filebeat -ComputerName $computer Get-Service -Name filebeat -ComputerName $computer | Restart-Service $filebeat_status_after = Get-Service -Name filebeat -ComputerName $computer [PSCustomObject]@{ ComputerN…

Get-Service with if/else checks

Landon, Welcome to the forum. Since I like re-usable output I’d use a slightly different approach and avoid Write-Host prosa with fancy colors … Besides this I’d recommend to avoid connecting to one computer more than once at a time. $ComputerList = Get-Content -Path 'C:\<file location>\Desktop\Machines.txt' $ServiceQueryList = Get-Content -Path 'C:\<file location>\ServiceList.txt' $Result = foreach ($ComputerName in $ComputerList) { if (Test-Connection -ComputerName $C…
