Member Function Documentation

collect()

bool collect ( )

virtual

Collect (update) the stats represented by this object.

Returns

true if the stats were collected successfully, false otherwise.

Implements SystemStats.

getCPUCount()

uint_t getCPUCount ( ) const

inline

Get the number of CPUs in the system.

getIdle()

float getIdle

(

int

cpu = -1

)

const

Get the percent of CPU time spent on the idle task.

Parameters

cpu	The CPU number or -1 for the average across all CPUs.

Exceptions

OutOfBoundsException

If the value of cpu is invalid.

getNice()

float getNice

(

int

cpu = -1

)

const

Get the percent of CPU time spent on low-priority tasks.

Parameters

cpu	The CPU number or -1 for the average across all CPUs.

Exceptions

OutOfBoundsException

If the value of cpu is invalid.

getSystem()

float getSystem

(

int

cpu = -1

)

const

Get the percent of CPU time spent in privileged (kernel) mode.

Parameters

cpu	The CPU number or -1 for the average across all CPUs.

Exceptions

OutOfBoundsException

If the value of cpu is invalid.

getUser()

float getUser

(

int

cpu = -1

)

const

Get the percent of CPU time spent in unprivileged (user) mode.

Parameters

cpu	The CPU number or -1 for the average across all CPUs.

Exceptions

OutOfBoundsException

If the value of cpu is invalid.

reset()

void reset ( )

virtual

Reset the stats object.

Implements SystemStats.
