$timeXtenderResult = Get-WmiObject Win32_LogicalDisk -ComputerName $computer_name -Filter 
"DeviceID!='A:' and FreeSpace<$limit_bytes"   | Select-Object  @{Name="Computer";

$computer_name = "{@computer_name[default:localhost][datatype:string][preview:localhost]}"

$limit_gb = 20

$limit_bytes = $limit_gb*1024*1024*1024

$timeXtenderResult = Get-WmiObject Win32_LogicalDisk -ComputerName $computer_name -Filter 
"DeviceID!='A:' and FreeSpace<$limit_bytes"   | Select-Object  @{Name="Computer";
Expression={$computer_name}},DeviceID,@{Name="Size GB";Expression={$_.Size / 1GB}},
@{Name="Free GB";Expression={$_.FreeSpace / 1GB}} | exMon-Out-DataTable
2. Create an object group and add the query to the object group, once for each server to monitor: 3. Add Extra Parameters to each query to specify which server to monitor:

--@computer_name es-srv-01
