Power shell Script to Compare Disk Space ,Patches and Service status before and after reboot of windows servers

A monitoring tool like SCCM or SCOM would be more efficient to do this kind of monitoring
Do you have anything like that deployed?

How many servers are you looking to run this on?

currently there is no tool available , and data looking for approx 250 boxes

if you want to get disk space of a remote system then thats not too hard - see example below from technet gallery

Depending on what you mean by compare that could be incredibly challenging to do well or at least fast when you are looking at 250 servers

Service status should also be easy, you could agument this to pull from a file and then you would need to write some logic where a service is automatic but not running

PS C:\Users\chris> Get-Service -ComputerName SERVER01 | select -property name,starttype |where {$_.starttype -like
"automatic"}

Getting patch status is a lot harder especially when you want to compare, you are essentially replicating the functionality of a system management tool this would be a much better and more efficient solution, i don't think there are any free ones that will cover it so you might need to look at buying something.

Take a look at Polymon. It's free. It's old - but it still works.

Thanks  Chris and Micheal

Can we use any script as using tool will be bit difficult to be approved for my banking  domain?
