cpu_nice_ratioTime spent on low-priority processes
cpu_iowait_ratioTime waiting for I/O operations
cpu_irq_ratioTime servicing hardware interrupts
cpu_softirq_ratioTime servicing software interrupts
cpu_steal_ratioTime stolen by hypervisor
cpu_guest_ratioTime running a guest OS
cpu_guestNice_ratioTime running a low-priority guest OS
