Get-ExchangeServer
As with most PowerShell cmdlets you can control the output display by piping the output into Format-List (or Format-Table).

Get-ExchangeServer -Identity ExSv1 | Format-List

Note 2:  If you want to focus on just one server append the -Identity parameter.
List the Get-ExchangeServer Parameters

Extend your scripting capabilities by getting to know more parameters:

Get-Help Get-ExchangeServer

Use the information to specify the status because it forces the cmdlet to include real-time information.  For example, try this script with and without the -Status switch.

Get-ExchangeServer -Identity ExSv1 -Status | Format-List
