Windows Server Environment Disk Usage monitoring solution?

Hi guys,

I have about 30 Win 2003/2008 servers which need to have Disk Capacity monitored, the snag is, heavy corporate IT policy governance towards third party applications.

Is there any bolt-on services/scripting I can use as a workaround? I basically need to create daily reports and perhaps alerts regarding capacity management, as some of our critical applications require space available across various volumes.

Thanks in advance.

Regards.

I use the above script to check on memory , hard disk space etc. . you , of course can remove whatever you do not need.
hope that helps

i failed to mention that you should copy the code and save it on a file with an .hta extention using a notepad editor.

@stergium How would I add more volumes?  Currently it only scans "C" drive.

Thanks in advance, again.

Best Practices: Disaster Recovery Testing

Besides backup, any IT division should have a disaster recovery plan. You will find a few tips below relating to the development of such a plan and to what issues one should pay special attention in the course of backup planning.

Hello again.
A not so smart solution would be to create functions like GetFreeSpace, GetTotalSpace with the corresponding driver letter.
i'm trying to create a loop though local logical drives.

from what i've tested (and actually had the chance to readjust the script for me also) this should give you all of the local hard disks.
