title: Track Time Processes Spend in Various States Using Tracepoints name: schedtimes.stp version: 1.0 author: Jason Baron keywords: process scheduler time tracepoint subsystem: scheduler status: production exit: user-controlled output: sorted-list scope: system-wide description: The schedtimes.stp script instruments the scheduler to track the amount of time that each process spends in running, sleeping, queuing, and waiting for io. On exit the script prints out the accumulated time for each state of processes observed. Optionally, this script can be used with the '-c' or '-x' options to focus on a specific PID and its children. test_support: stap -l 'kernel.trace("sched_switch")' && stap -l 'kernel.trace("sched_wakeup")' test_check: stap -p4 schedtimes.stp test_installcheck: stap schedtimes.stp -T 1
