TAPSET::TASK_TIME(3stap) TAPSET::TASK_TIME(3stap)

NAME

tapset::task_time - systemtap task_time tapset

DESCRIPTION


Task time query and utility functions provide information about
the time resource usage of the current task. These functions provide
information about the user time and system time of the current
task. And provide utility functions to turn the reported times
into miliseconds and create human readable string representations
of task time used. The reported times are approximates and should
be used for "coarse grained" measurements only. The reported user
and system time are only for the current task, not for the process
as a whole nor of any time spend by children of the current task.

User time of the task
See function::task_utime(3stap)
for details.
User time of the task

System time of the task
See function::task_stime(3stap)
for details.
System time of the task
See function::task_stime(3stap)
for details.
Start time of the given task
See function::task_start_time(3stap)
for details.
Translates the given cputime into milliseconds
See function::cputime_to_msecs(3stap)
for details.
Translates the given cputime into microseconds
See function::cputime_to_usecs(3stap)
for details.
Human readable string for given milliseconds
See function::msecs_to_string(3stap)
for details.
Human readable string for given microseconds
See function::usecs_to_string(3stap)
for details.
Human readable string for given nanoseconds
See function::nsecs_to_string(3stap)
for details.
Human readable string for given cputime
See function::cputime_to_string(3stap)
for details.
Human readable string of task time usage

for details.
Human readable string of task time usage
