How to measure core utilization?

I'm new to ARM so please bear with me. I searched this forum and didn't find anything relevant (or maybe I didn't search well enough), so I'm posting my question here.

In the microprocessor world, we have the notion of CPU utilization and we can measure it. In the STM32 (ARM Cortex M4 in particular), is there such a concept? How would I know if I have overburdened my MCU with - say - complex floating point code executing in ISR mode?
