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.

task_utime

User time of the current task

See function::task_utime(3stap)
for details.

task_utime_tid

User time of the given task

See function::task_utime_tid(3stap)

task_stime

System time of the current task

See function::task_stime(3stap)
for details.

task_stime_tid

System time of the given task

See function::task_stime_tid(3stap)
for details.
