| percent/jiffies | nice | Time the CPU spent running user space processes that have been niced. The priority level a user space process can be tweaked by adjusting its niceness. | ||||
| percent/jiffies | interrupt | Time the CPU has spent servicing interrupts. | ||||
| percent/jiffies | softirq | |||||
| percent/jiffies | steal | CPU steal is a measure of the fraction of time that a machine is in a state of “involuntary wait.” It is time for which the kernel cannot otherwise account in one of the traditional classifications like user, system, or idle. It is time that went missing, from the perspective of the kernel. http://www.stackdriver.com/understanding-cpu-steal-experiment/ | ||||
| percent/jiffies | system | Time that the CPU spent running the kernel. | ||||
| percent/jiffies | user | Time CPU spends running un-niced user space processes. | ||||
| percent/jiffies | wait | The time the CPU spends idle while waiting for an I/O operation to complete | ||||
