title: Generate Backtraces of Threads Waiting for IO Operations name: sleepingBeauties.stp version: 1.0 author: anonymous keywords: io scheduler backtrace subsystem: scheduler status: proposed exit: user-controlled output: trace scope: system-wide description: The script monitors the time that threads spend in waiting for IO operations (in "D" state) in the wait_for_completion function. If a thread spends over 10ms, its name and backtrace is printed, and later so is the total delay. test_check: stap -p4 sleepingBeauties.stp test_installcheck: stap sleepingBeauties.stp -T 1
