Recently, I had the need to run a logical disk free space report and knowing that this isn’t provided out of the box I created a report and put it into a new management pack. I was then approached about collecting fragmentation data on each drive as well and this got me thinking, why don’t I create an MP that extends the standard management of logical disks. So, I created it !
This management pack collects 21 different statistics on each managed logical drive. These counters are…
- Average File Size
- Average Fragments per File
- Cluster Size
- Excess Folder Fragments
- File Percent Fragmentation
- Fragmented Folders
- Free Space
- Free Space Percent
- Free Space Percent Fragmentation
- MFT Percent in Use
- MFT Record Count
- Total Excess Fragments
- Total Files
- Total Folders
- Total Fragmented Files
- Total MFT Fragments
- Total MFT Size
- Total Page File Fragments
- Total Percent Fragmentation
- Used Space
- Volume Size
Collecting this many counters created its own challenge as I didn’t want to have to run a script multiple times to collect each counter or run it for each drive. To combat this challenge I wrote a data source that all the collection rules use. This data source contains a VBS script that will only run once per server at the scheduled time and collect all 21 pieces of data for each and every logical drive on that server. Writing a data source and rules like this means that cookdown does not get broken and is the most efficient way of collecting and monitoring data.
This management pack also contains a “Free Space” report and a “Top 10 fragmented logical drives” report as well as performance, state and dashboard views for you to consume all the collected data. And, there is also a task to analyze whether a logical drive requires defragmentation or not.
Click the following link if you want to download the MP or review the guide for more information, http://www.systemcentercentral.com/tabid/145/IndexId/64216/Default.aspx. The download will include a sealed copy of the MP, an unsealed copy of the MP and the MP guide.
I hope you find it useful and please let me have and feedback, good or bad, that you may have

Hello David, This looks quite promising. The guide does not appear on the download. Is there another link for a copy of that pls?
Thx,
John Bradshaw

I have selected the 1024 Space Limit and selected All windows computers, Since from 1 Hour the report is genearting and got Connection timedout
Is there any methos where i can select the particular computer to generate the free space report
Yugandhar, Did you ever get this problem fixed? I’m having the exact same issue. It is monitoring fine, but the reports will not show up. I will also go to the Logical Drive State and over on the right I can click the ‘Free Space Report’ but then it gives me this error:
"The item ‘/Windows.LogicalDrives/Windows.LogicalDrives.FreeSpace.Report’ cannot be found. (rsItemNotFound)"
