Introduction

I am sure monitoring windows servers in a regular interval is a painstaking and boring task for administrators. To minimize this tedious task, this script will be helping you to ease your life. In this script I used Microsoft.SharePoint.PowerShell and Windows Management Instrumentation (WMI) classes.

Background

As a SharePoint administrator I had to monitor 5 servers only within the sharepoint farm. In order to check free hard disk space either it is needed to logging to the each server or it is needed to have a 3^rd party tool for monitor all the servers remotely. So that with the use of this script it is lot easier to monitor all the servers with single SharePoint list.

Using the code

Before using this code you must check following factors:

Since we are using Microsoft.SharePoint.PowerShell module you must run this on a server which have install SharePoint foundation or SharePoint server better you run this on SharePoint server.
Make sure all the servers firewall allow the traffic about WMI

further, you have to create a sharepoint list as follows.

and in order to run this script after perticuler time period you can schedule it

$ServerName = Get-Content "C:\PS\Computers.txt"
$ConvertToGB = (1024 * 1024 * 1024)
#$BeginDate=[System.Management.ManagementDateTimeConverter]::ToDMTFDateTime((get-date).AddDays(-1))
#$filter = "LogFile='application' OR LogFile='system' AND EventType=1 AND TimeWritten>'$BeginDate'"
$spWeb = Get-SPWeb http://sharepointsite/xxx/xxx/
$spList = $spWeb.Lists["listname"] 
foreach ($Server in $ServerName) {
    $newItem = $splist.Items.Add()
    $option = $Server -split " "
    $disk = Get-WmiObject Win32_LogicalDisk -ComputerName $option[1] -Filter $option[2] | Select-Object Size,FreeSpace
    $option[1] + "," + [math]::Round($disk.Size / $ConvertToGB) + "," + [math]::Round($disk.FreeSpace / $ConvertToGB)
    if($option[3] -eq $null) {} else {
    $disk2 = Get-WmiObject Win32_LogicalDisk -ComputerName $option[1] -Filter $option[3] | Select-Object Size,FreeSpace
    $option[1] + "," +  [math]::Round($disk2.Size / $ConvertToGB) + "," + [math]::Round($disk2.FreeSpace / $ConvertToGB)
    $newItem["FreeSpace-Other"] = [math]::Round($disk2.FreeSpace / $ConvertToGB)
    }
$PSSnapin = Remove-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue | Out-Null
$PSSnapin = Add-PsSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue |    Out-Null
$newItem["Title"] = $option[1]
$newItem["ServerName"] = $option[0]
$newItem["FreeSpace-OS"] = [math]::Round($disk.FreeSpace / $ConvertToGB)
$newItem.Update()
}

and text file should like following

machinename ip DeviceID='C:'
machinename ipaddress DeviceID='C:' DeviceID='E:'

Points of Interest

$disk = Get-WmiObject Win32_LogicalDisk -ComputerName $option[1] -Filter $option[2] | Select-Object Size,FreeSpace
