Check Uptime for Multiple Servers using PowerShell - GUI based tool

This tool will help you to determine the uptime for multiple servers.

Script:

Function Get-Uptime{
Param([string]$server)
Begin {
function PingServer {
Param([string]$srv)
$pingresult = Get-WmiObject win32_pingstatus -f "address=’$srv’"
if($pingresult.statuscode -eq 0) {$true} else {$false}
}
function myUptime {
param([string]$srv)
$os = Get-WmiObject Win32_OperatingSystem -ComputerName $srv
$uptime = $os.LastBootUpTime
return $uptime
}
function ConvertDate {
param([string]$date,[string]$srv)
$year = $date.substring(0,4)
$Month = $date.Substring(4,2)
$day = $date.Substring(6,2)
$hour = $date.Substring(8,2)
$min = $date.Substring(10,2)
$sec = $date.Substring(12,2)
$RebootTime = new-Object System.DateTime($year,$month,$day,$hour,$min,$sec)
$now = [System.DateTime]::Now
$uptime = $now.Subtract($RebootTime)
$uptimeval = "$($uptime.days) days, $($uptime.Hours) hours, $($uptime.Minutes) minutes, $($uptime.seconds) seconds"
$lastReboot = $rebootTime.toString()
$sObject = new-Object -typename System.Object
$sObject | add-Member -memberType noteProperty -name ServerName -Value $srv
$sObject | add-Member -memberType noteProperty -name Days -Value $uptime.days
$sObject | add-Member -memberType noteProperty -name Hours -Value $uptime.Hours
$sObject | add-Member -memberType noteProperty -name Minutes -Value $uptime.Minutes
$sObject | add-Member -memberType noteProperty -name Seconds -Value $uptime.seconds

$sObject | add-Member -memberType noteProperty -name LastReboot -Value $rebootTime.ToUniversalTime()
$sObject | add-Member -memberType noteProperty -name LastRebootUtc -Value $rebootTime.ToFileTimeUtc()
write-Output $sObject
}
Write-Host
$process = @()
$objCollection = @()
}
Process {
if($_){
if($_.ServerName ){
$process += $_.ServerName
}
else{
$process += $_
}
}
}
End {
if($Server){$process += $server}
$i = 1
foreach ($Server in $process){
write-progress $Server "Total Progress->" -percentcomplete ($i/$process.length*100)
if(PingServer $server){
