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 <sys.monitoring>` 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.
