David is correct. The system or non-system is calculated by the monitoring script at runtime.
The easiest way obviously is to group based on "C" drive or not... however there will be exceptions for the systems that don't use the C drive for the system disk. If you create a new class, and add the property, you will essentially double the instances of logical disks on each agent. For a small environment this likely won't be much of an issue. But for a large environment you must take care not to create a massive instance space or you can impact performance of the management group.

Without this, you cannot group on it. You could add a new attribute to the class to discover whether it is a system drive or not, and then that attribute will be available to group on.

I am trying to build a group definition of disks system and non-system based on size. I can create a group using Logical Disk(server) objects and choose the size attribute. My challenge is to get the group based on this and if a system drive or not.

This is fine My question is this how does the monitor know what is a system disk and what is a non-system drives?
