GET-Memory Useage function

Created a function to check the memory usage  on multiple servers



 Function Get-MemoryUsage ($ComputerName=$ENV:ComputerName) {
[cmdletbinding()]
$os = Get-Ciminstance Win32_OperatingSystem -ComputerName $ComputerName
$totalvisibleMemmorysize=$os.TotalvisibleMemmorysize
$pctFree = [math]::Round(($os.FreePhysicalMemory/$os.TotalVisibleMemorySize)*100,2)
$ser=$os.CSName

if ($pctFree -ge 45) {
$Status = "OK"
}
elseif ($pctFree -ge 15 ) {
$Status = "Warning"
}
else {
$Status = "Critical"
}

$os | Select @{Name = "Servername";Expression = {$ser}},
 @{Name = "TotalGB";Expression = {[int]($_.TotalVisibleMemorySize/1mb)}},
@{Name = "FreeGB";Expression = {[math]::Round($_.FreePhysicalMemory/1mb,2)}},
@{Name = "PctFree%"; Expression = {$pctFree}},@{Name = "Status";Expression = {$Status}} | Format-Table -AutoSize
}

Getting System Up time in Customized display

# Getting System Up time in Customized display
#Using this Script you can get the uptime of  multiple servers
#save the servers list in notepad with  out spaces.it will use to save the time if you want query the uptime of bulk servers.Please contact me for for any sugesstions and feedback
