SCOM 2012 disk space monitoring

Have you already found the Technet Documentation on Tuning and Overrides?
I believe the Windows 2012 Operating System Management Pack is built in to the default install of SCOM... but whether it is or not, you can pull down the latest version from the MIcrosoft Download Center.  

If you have different thresholds you want to set, but have a few different classes of those thresholds, I'd be tempted to create groups of drives ('Authoring', 'Groups', Create new group, and use the wizard to define which Logical drives you want in each group.)...

Then in Authoring, Management Pack Objects, Monitoring, find the what you want to monitor.  I assume, for example, Windows Server 2012 Logical Disk : Logical Disk Free Space, and Override > Override the monitor > for a group, and define the differences for the that group of logical disks.

Creating the groups are optional, you CAN define different thresholds for each different disk.

Hi,

Thanks for your response. I have gone through the steps you mentioned above. In order for the override to take effect could you advise if I have checked the relevant boxes in order for the override to take effect? Could you also advise if an alert will be generated if the disk space exceeds the threshold?

I have attached a screenshot override properties.

Thanks,
