py_malloc.d(1m)

NAME
py_malloc.d - Python libc malloc analysis.

SYNOPSIS
py_malloc.d { -p PID | -c cmd }

DESCRIPTION
This is an expiremental script to identify who is calling malloc() for memory allocation, and to print distribution plots of the requested bytes. If a malloc() occured while in a Python function, then that function is identified as responsible; else the caller of malloc() is identified as responsible - which will be a function from the Python engine. Filename and function names are printed if available.

OS
Any

STABILITY
Evolving - uses the DTrace Python provider, which may change as additional features are introduced. Check Python/Readme to see what version these scripts are based on.

EXAMPLES

Default output,
    # py_malloc.d

DOCUMENTATION
See the DTraceToolkit for further documentation under the Examples, Notes and Docs directories. The example files may be especially useful as they aim to demonstrate how to interpret the output.

EXIT
py_malloc.d will run until Ctrl-C is hit.
