title: Show Time Spent on Each Line of a Function name: linetimes.stp version: 1.0 author: William Cohen keywords: profiling subsystem: any status: production exit: user-controlled output: sorted-list scope: system-wide description: The linetimes.stp script takes two arguments: where to find the function and the function name. linetimes.stp will instrument each line in the function. It will print out the number of times that the function is called, a table with the average and maximum time each line takes, and control flow information when the script exits. test_check: stap -p4 linetimes.stp kernel sys_nanosleep test_installcheck: stap linetimes.stp kernel sys_nanosleep -c "sleep 0.2"
