idlestat
measure CPU time in idle and operating states
Idlestat uses kernel FTRACE function to monitor and capture C-state and P-state transitions of CPUs over a time interval. It calculates the total, average, min and max times spend in each C-state, P-state for each CPU and in each CPU cluster. It also reports the times specific IRQs caused the CPU to exit idle state, per CPU and per-IRQ.
