Find the HDD space everyday

Sharath,

there is a similar thread on EE ... which talks about a script which checks the drive space before running a different command..

you could use the same script.. but just modify it as u might deem fit..

Hi Sharath,

Here is a script I use to check hard drive space, but it does not keep a log as yet.  It could easily be changed to do that though, if you would like that.
'============

Option Explicit

Dim strComputer, objWMIService, colDisks, objDisk, intFreeSpace, intTotalSpace, pctFreeSpace, strDetails

strComputer = InputBox("Please enter the computer that you wish to get the free space from:", "Free Space", "NTFP")

Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colDisks = objWMIService.ExecQuery _
    ("Select * from Win32_LogicalDisk Where DriveType = 3")
For Each objDisk in colDisks
    intFreeSpace = objDisk.FreeSpace
    intTotalSpace = objDisk.Size
    pctFreeSpace = intFreeSpace / intTotalSpace
    strDetails = strDetails & objDisk.DeviceID & " - Total: " & Round(intTotalSpace / (1024 * 1024 * 1024), 2) & " - Free: " & Round(intFreeSpace / (1024 * 1024 * 1024), 2) & " GB - " & FormatPercent(pctFreeSpace) & " free" & vbCrLf
Next

MsgBox strDetails

Yes rob i want it to have a log maintained on every hr or 2 hrs basis.

Actually what i want is.To keep a record on todays space and then run every day to check the difference

Hi Sharath,

Please try this script:

It will output to a CSV file, which you can change the name of with
strLogFileName = "HardDiskSpaceLog.csv"

This work under the assumption that there are three physical drives located on the server (C, D, and E).
If your server is different, let me know, and I will change the field references for you.

It records the difference in GB from when you run it, to that value from the previous time it was run.

Regards,

Rob.

I get this.

Date      Computer      C Total (GB)      C Free      C % Free      D Total (GB)      D Free      D % Free      E Total (GB)      E Free      E % Free      C Diff      D Diff      E Diff
7/27/2007 8:24      dev-chen-mrd100      24.41      15.84      64.89%      124.63      91.1      73.10%      39.07      12.11      31.01%      35.49      6.61      18.64%

What does C diff mean.

I have different machines with different Partitions in this case it is C,D,E,F.Is there a way to let the script search till F.If there is a machine which has until D then search without any errors.

Need to allow the script to search C,D,E,F,G,H,I drives

OK, I've tried to make it completely automatic, to pick up all Physical drives.....try this:

Oh doh!  I forgot one bit.

Change these three lines:
      strDetails = strDetails & "," & Split(strLastLine, ",")(2) - Split(strDetails, ",")(2)
      strDetails = strDetails & "," & Split(strLastLine, ",")(5) - Split(strDetails, ",")(5)
      strDetails = strDetails & "," & Split(strLastLine, ",")(8) - Split(strDetails, ",")(8)

To this:
      For intCount = 1 To intDriveCount
            If intCount = 1 Then
                  strDetails = strDetails & "," & Split(strLastLine, ",")(2) - Split(strDetails, ",")(2)
            Else
                  strDetails = strDetails & "," & Split(strLastLine, ",")(2 + (intCount - 1) * 3) - Split(strDetails, ",")(2 + (intCount - 1) * 3)
            End If
      Next

And it will calculate the right differences.

Oh, and run it two or three times, you'll see that the C Diff, D Diff columns, etc, will be zero, because the values haven't changed.

Regards,

Rob.

But now its creating new file for each search.I want a single file.
Now its not showing the C difference

Yeah, I made it make a new file per server, because the amount of drives are going to be different per server, so they will need to keep separate log files.
I should continue to append to that server's log file, if it already exists.

Rob.

Ok thanks .

One small problem

I ran the script on a machine 3 times and made some changes on the drives.

But i still see the Difference as 0

Doh!  The calculation is happening from the Total, which will never change!  Stupid me!

I'll change it.....

Thanks a lot..

No problem.  I like that actually.  I originally had it only outputting the values to screen, but this logging has potential for good historical data.
