title: Show functions taking longer than usual
name: fntimes.stp
keywords: profiling
description: The fntimes.stp script monitors the execution time history of a given function family (assumed non-recursive). Each time (beyond a warmup interval) is then compared to the historical maximum. If it exceeds a certain threshold (250%), a message is printed.
test_check: stap -p4 fntimes.stp 'kernel.function("sys_*")'
test_installcheck: stap fntimes.stp 'kernel.function("sys_*")' -c "sleep 7"
