Enum Constant Summary

Enum Constants

Enum Constant and Description
IDLE Time that the CPU or CPUs were idle and the system did not have an outstanding disk I/O request.
IOWAIT Time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request.
IRQ Time that the CPU used to service hardware IRQs
NICE CPU utilization that occurred while executing at the user level with nice priority.
SOFTIRQ Time that the CPU used to service soft IRQs
STEAL Time which the hypervisor dedicated for other guests in the system.
SYSTEM CPU utilization that occurred while executing at the system level (kernel).
USER CPU utilization that occurred while executing at the user level (application).

Enum Constant Detail

USER

public static final CentralProcessor.TickType USER

CPU utilization that occurred while executing at the user level (application).

NICE

public static final CentralProcessor.TickType NICE

CPU utilization that occurred while executing at the user level with nice priority.

SYSTEM

public static final CentralProcessor.TickType SYSTEM

CPU utilization that occurred while executing at the system level (kernel).

IDLE

public static final CentralProcessor.TickType IDLE

Time that the CPU or CPUs were idle and the system did not have an outstanding disk I/O request.

IOWAIT

public static final CentralProcessor.TickType IOWAIT

Time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request.

IRQ

public static final CentralProcessor.TickType IRQ

Time that the CPU used to service hardware IRQs

SOFTIRQ

public static final CentralProcessor.TickType SOFTIRQ

Time that the CPU used to service soft IRQs

STEAL

public static final CentralProcessor.TickType STEAL

Time which the hypervisor dedicated for other guests in the system. Only supported on Linux.

Method Detail

values

public static CentralProcessor.TickType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CentralProcessor.TickType c : CentralProcessor.TickType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CentralProcessor.TickType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getIndex

public int getIndex()

Returns:

The integer index of this ENUM in the processor tick arrays, which matches the output of Linux /proc/cpuinfo
