feat(crashtracking): hook based exception profiling for versions 3.12+ by gyuheon0h · Pull Request #16567 · DataDog/dd-trace-py

gyuheon0h · 2026-02-18T23:19:53Z

Description

This PR adds exception profiling to dd-trace-py for Python versions 3.12+. The exception collector captures handled exceptions along with their stack traces and reports them as profiling samples. This gives users visibility into exception hotspots in their applications: which exception types are thrown most frequently, where they originate, and optionally what messages they carry.

Architecture

RFC

The ExceptionCollector is a new profiling collector that hooks into the Python runtime to detect when exceptions are handled. It uses two different mechanisms depending on the Python version:

Python 3.12+: sys.monitoring API:

The collector registers a callback for sys.monitoring.events.EXCEPTION_HANDLED using the PROFILER_ID tool slot. When an exception is caught by an except block anywhere in the application, CPython fires the EXCEPTION_HANDLED event and our _on_exception_handled callback receives the code object, instruction offset, and the exception object directly. sys.monitoring is an API introduced in PEP 669.

Sampling

Both callbacks use Poisson sampling to limit overhead. A Cython implementation (_fast_poisson.pyx) draws the next sample interval from a Poisson distribution with configurable mean (default: 100). This means on average 1 in every 100 exceptions is captured, enough for statistical profiling while keeping hot-path overhead to a single integer comparison and increment for non-sampled exceptions. The PRNG uses SplitMix64 seeded from os.urandom.

Sample collection

When an exception is sampled, _collect_exception creates a ddup.SampleHandle and pushes:

Exception type (as module.ClassName)
Exception message (if collect_message is enabled; new C++ label exception_message added to the libdatadog bridge)
Thread info (thread id, native id, name)
Stack frames from the traceback (up to max_nframe, reversed to bottom-up order)

The sample is flushed to the ddup C++ library which encodes it in pprof format for upload.

Configuration

New environment variables under DD_PROFILING_EXCEPTION_*:

Variable	Default	Description
`DD_PROFILING_EXCEPTION_ENABLED`	`false`	Enable/disable exception profiling
`DD_PROFILING_EXCEPTION_SAMPLING_INTERVAL`	`100`	Mean number of exceptions between samples
`DD_PROFILING_EXCEPTION_COLLECT_MESSAGE`	`true`	Whether to capture exception message strings

Testing

Unit tests. Ran on a test app. Will write prof-correctness for this also
