Do you know how to check the cpu when the switches (3750) are in stack. Also in switch stack when you issue "show process cpu" command, does it show the master switch cpu or the overall cpu usages of the stack swtiches.
When the switches are in stack, the master's CPU does everything. The other ones just run a minimal process to talk to each other. In other words, there is no process sharing or multi-processor architecture to speak of.
So, no command to check individual units CPU, and no need for it.
