script examples determining time spent in kernel and user space examples of SystemTap scripts determining time spent in kernel and user space determining time spent in kernel and user space examples of SystemTap scripts time spent in kernel/user space, determining examples of SystemTap scripts kernel and user space, determining time spent in examples of SystemTap scripts user and kernel space, determining time spent in examples of SystemTap scripts http://sourceware.org/systemtap/examples/profiling/thread-times.stp This section illustrates how to determine the amount of time any given thread is spending in either kernel or user-space. script examples CPU ticks examples of SystemTap scripts CPU ticks CPU ticks examples of SystemTap scripts lists the top 20 processes currently taking up CPU time within a 5-second sample, along with the total number of CPU ticks made during the sample. The output of this script also notes the percentage of CPU time each process used, as well as whether that time was spent in kernel space or user space. contains a 5-second sample of the output for : tid %user %kernel (of 20002 ticks) 0 0.00% 87.88% 32169 5.24% 0.03% 9815 3.33% 0.36% 9859 0.95% 0.00% 3611 0.56% 0.12% 9861 0.62% 0.01% 11106 0.37% 0.02% 32167 0.08% 0.08% 3897 0.01% 0.08% 3800 0.03% 0.00% 2886 0.02% 0.00% 3243 0.00% 0.01% 3862 0.01% 0.00% 3782 0.00% 0.00% 21767 0.00% 0.00% 2522 0.00% 0.00% 3883 0.00% 0.00% 3775 0.00% 0.00% 3943 0.00% 0.00% 3873 0.00% 0.00%
