powershell to Ping,RDP,RemoteRegistry,WMI - powershell

Question

I wrote a Powershell script that will perform Ping, RDP(3389), Remote Registry and WMI connectivity to a remote computer. Below is the script that I have come up with. Now I would like to get the output in a short format such as:
PING : SUCCESS
RDP : FAIL
Remote Registry : FAIL
WMI : SUCCESS
Remote Registry check has FAILED.
RDP check has FAILED.
PING check SUCCEEDED
WMI check SUCCEEDED
I am looking for help as I am new to Powershell scripting. Thank you in advance!!
Write-Host `n
$inputfromuser = Read-Host "Enter Server Name"
If($inputfromuser -like "")
{
Write-Host "User Input cannot be blank. Please enter the server name"
Write-Host `n
}
else
{
Write-Host `n
Write-Host -ForegroundColor Yellow "CHECKING PING CONNECTIVITY TO SERVER $inputfromuser"
Test-Connection -ComputerName $inputfromuser -Quiet -Count 1
Write-Host `n
Write-Host -ForegroundColor Yellow "CHECKING RDP PORT 3389 CONNECTIVITY ...."
Test-NetConnection -ComputerName $inputfromuser -CommonTCPPort RDP -InformationLevel Quiet
Write-Host `n
Write-Host -ForegroundColor Yellow "CHECKING REMOTE REGISTRY CONNECTIVITY ...."
$regkey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,$inputfromuser)
$ref = $regkey.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall")
If (!$ref) {
Write-Host -ForegroundColor Red "REMOTE REGISTRY CHECK FAILED"
}
Else {
Write-Host -ForegroundColor Green "REMOTE REGISTRY CHECK SUCCESS"
}
Write-Host `n
Write-Host -ForegroundColor Yello "CHECKING REMOTE WMI CONNECTIVITY ...."
$wmi = GWMI -Query "Select * from Win32_PingStatus where Address = '$inputfromuser'"
If (!$wmi) {
Write-Host -ForegroundColor Red "REMOTE WMI CHECK FAILED"
}
Else {
Write-Host -ForegroundColor Green "REMOTE WMI CHECK SUCCESS"
}
Write-Host `n
}

I'd recommend separating tests from output creation. Assign the results of your checks to separate variables:
$ping = Test-Connection ...
$rdp = Test-NetConnection ...
$regkey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $inputfromuser)
$ref = $regkey.OpenSubKey("...")
$wmi = Get-WmiObject -Query "..."
create 2 hashtables:
$state_noun = #{
$true = 'SUCCESS'
$false = 'FAIL'
}
$state_verb = #{
$true = 'SUCCEEDED'
$false = 'FAILED'
}
and create the output with a here-string:
$result = #"
PING : $($state_noun[$ping])
RDP : $($state_noun[$rdp])
Remote Registry : $($state_noun[[bool]$ref])
WMI : $($state_noun[[bool]$wmi])
Remote Registry check has $($state_verb[[bool]$ref]).
RDP check has $($state_verb[$rdp]).
PING check $($state_verb[$ping])
WMI check $($state_verb[[bool]$wmi])
"#
Write-Host $result
If you must have highlighted/colored values in your output, use a custom output function like this:
function Write-Result {
[CmdletBinding()]
Param(
[Parameter()][string]$text,
[Parameter()][bool]$value
)
Write-Host $text -NoNewline
if ($value) {
Write-Host $value -NoNewline -ForegroundColor Green
} else {
Write-Host $value -NoNewline -ForegroundColor Red
}
Write-Host '.'
}
Write-Result 'PING : ' $state_noun[$ping]
...
Write-Result 'Remote Registry check has ' $state_verb[[bool]$ref]
...
