PEP 669: Low impact monitoring for CPython ------------------------------------------ -CPython 3.12 now supports the ability to monitor calls, -returns, lines, exceptions and other events using instrumentation. +:pep:`669` defines a new :mod:`API ` for profilers, +debuggers, and other tools to monitor events in CPython. +It covers a wide range of events, including calls, +returns, lines, exceptions, jumps, and more. This means that you only pay for what you use, providing support for near-zero overhead debuggers and coverage tools. - See :mod:`sys.monitoring` for details. +(Contributed by Mark Shannon in :gh:`103083`.)
