Dear All,

We are having environment of more then 200 Production Servers which are Critical  hence we need to Monitor and Report the Disk Space  through SCRIPT using PowerShell  or VB. If any body has already been done , Kindly share it.

Thanks & Regards,
Amit Satam

Dear Gandalf,

If I want to Test the above Script in one of the Machine , Do I need to simply execute the the PS Script or any alteration are required in it.

Thanks & Regards,
Amit Satam

to run it against one machine type c:\script_path\'hard drive report to html.ps1' computer1 or use a list of computers in a text file with each computer name on a separate line. use 

change line 7   $computers = (Get-Content "C:\Scripts\Computers.txt")    to point to your computer list name and  path

the results will open in your default browser

Try the following to export the results to Excel which will break the numbers up into several columns.

Also, create a list of the server names in a text file and save it to C:\ as Servers.txt

You may also have to set the execution policy if you have not done so.  Open Powershell as Admin and type set-executionpolicy remotesigned

HI, you need to define the output file path.

Example:

#Out put path
$Path = "D:\dp.htm"

Dilip...Can you tell us ...how to email the output htm to out mail box.

Thanks
Azam

Dear you have to use Function sendmail of PowerShell.

refer the below example if the script. this is ready script you just need to change the below things.

1. server.list (Add the IP and name of the server)

2. Add SMTP IP address

3. replace xxx@test.com with your real email id.

# First lets create a text file, where we will later save the freedisk space info
$freeSpaceFileName = "FreeSpace.htm"
$serverlist = "Serverlist.txt"

Dilip,

If i am just interested in the servers drives which has croosed the TH leve i.e in this case $critical = 10.

I should only receive email with the servers whose drive space has reached the critical level.

Curious to know ...how to tweak like this.

Thanks in Advance.

you can attach a task to event log 2013, source SRV, which is logged when a disk is near capacity.

Log name: System

Source: Srv

EventID:  2013

I would also like to know this, I only like to get notified if a server is less than % level.

Hi,

Ive tryed to use your code but i have some problems, from what i see your code is writen for a domain, so that the executer of this Code doenst have restrictions to get the informations for the Given PC, i have 10PCs and i want to monitor their free space but i always get this "HRESULT: 0x80070005 (E_ACCESSDENIED)" when i execute it on each PC with localhost it works, but not on my whole network. So how do i Login indivitualy to each PC?

Thanks for the help.

I'm not seeing anyone using the Get-Volume cmdlet as a basis for this task. Seems like it could be helpful.

Dear Gandalf,

Its nice but can we display IP address with respect to drive space  instead of hostname in report??

Please reply..

Hi,

Ive tryed to use your code but i have some problems, from what i see your code is writen for a domain, so that the executer of this Code doenst have restrictions to get the informations for the Given PC, i have 10PCs and i want to monitor their free space but i always get this "HRESULT: 0x80070005 (E_ACCESSDENIED)" when i execute it on each PC with localhost it works, but not on my whole network. So how do i Login indivitualy to each PC?

Thanks for the help.

Did you ever resolve your issue of accessing non-domain joined PCs with this script?

When i run have error

Great job and thanks for posting.

Here is the another script that can be utilized for this purpose, we are using this in our environment.

http://gallery.technet.microsoft.com/scriptcenter/Disk-Space-and-Threshold-48aa62d5

If someone is interested, I added the following line to the HTML script report to add the percentage free (the line in bold):

#create an html fragment 
    $html=$drives | Select @{Name="Drive";Expression={$_.DeviceID}}, 
    @{Name="SizeGB";Expression={$_.Size/1GB  -as [int]}}, 
    @{Name="UsedGB";Expression={"{0:N2}" -f (($_.Size - $_.Freespace)/1GB) }}, 
    @{Name="FreeGB";Expression={"{0:N2}" -f ($_.FreeSpace/1GB) }}, 
@{Name="PercentageFree";Expression={"{0:N2}" -f [Math]::round((($_.Freespace)/$_.Size)*100) }}, 
    @{Name="Usage";Expression={ 
      $UsedPer= (($_.Size - $_.Freespace)/$_.Size)*100 
      $UsedGraph=$g * ($UsedPer/2) 
      $FreeGraph=$g* ((100-$UsedPer)/2) 
      #I'm using place holders for the < and > characters 
      "xopenFont color=Redxclose{0}xopen/FontxclosexopenFont Color=Greenxclose{1}xopen/fontxclose" -f $usedGraph,$FreeGraph 
    }} | ConvertTo-Html -Fragment
