How to check multiple services on different servers in powershell scripting? - powershell

Question

I have 3 servers
server a, server b, server c
I want to check 3 services,
service = serva, servb, servc
server a contains serva and servb
server b contains servb and serv c
server c contains servc only
I already seen a script for checking different services on different servers but i cannot think of a way to edit it to fit to my needs. Can anyone help me please on how to check multiple servies (some are the same) in different servers?

Answer 1

Here is one way to do this:
$services = #( #{Computername="ServerA"; ServiceName="ServiceA"},
#{Computername="ServerA"; ServiceName="ServiceB"},
#{Computername="ServerB"; ServiceName="ServiceB"},
#{Computername="ServerB"; ServiceName="ServiceC"},
#{Computername="ServerC"; ServiceName="ServiceC"}
)
$services | %{Get-Service -Computername $_.Computername -ServiceName $_.ServiceName}
# Because I used a hashtable with full parameter names for $services, I can do this trick
$services | %{Get-Service #_ }
Now I did a lot of advanced stuff there. We can make this smpler by putting your data in a CSV file. Just use ComputerName and ServiceName as the columns to fit this example. Just have one server and one service on each line.
$services = Import-CSV servicelist.txt
$services | %{Get-Service -Computername $_.Computername -ServiceName $_.ServiceName}
The default output may not show the computer name so it would be a good idea to pipe it to a Select-Object MachineName, Name, Status.
