PyVmMonitor

PyVmMonitor is a profiler with a simple goal: being the best way to profile a Python program.

• Attach profiler to a running (CPython) program
• Deterministic profiling through cProfile/profile integration
• On demand profiling with Yappi integration
• Analyze existing PStats results
• Open DOT files
• Programatic API access
• Profile on a different machine
• Multiple processes support (multiprocessing, django...)
• Live sampling/CPU view
• Select time range
• Group samples by method or line
• PyDev integration
• PyCharm integration

Release notes: 3.0.0

• Python versions from 3.7 up to 3.11 are now fully supported.
• Attach to process is now available for these versions.
• yappi pre-built binaries for Windows are available for these versions as well as Python 3.12.
• On other systems a `pip install yappi` is required so that yappi is available in the system being profiled.
• Python 3.12 has all features except attach to process.
• i.e.: to use with Python 3.12, it needs to be attached from the command line or by editing code to do the attach.
