Pympler is a development tool to measure, monitor and analyze the memory behavior of Python objects in a running Python application.
By pympling a Python application, detailed insight in the size and the lifetime of Python objects can be obtained. Undesirable or unexpected runtime behavior like memory bloat and other "pymples" can easily be identified.
Pympler integrates three previously separate modules into a single, comprehensive profiling tool. The asizeof module provides basic size information for one or several Python objects, module muppy is used for on-line monitoring of a Python application and module tracker provides off-line analysis of the lifetime of selected Python objects.
Pympler is written entirely in Python, with no dependencies to external libraries or projects. Both the tracker and the muppy module will work with Python 2.4, 2.5, and 2.6. The asizeof module has been tested with Python 2.2.3, 2.3.7, 2.4.5, 2.5.1, 2.5.2, 2.6 or 3.0rc1 on CentOS 4.6, SuSE 9.3, MacOS X 10.4.11 Tiger (Intel) and Panther 10.3.9 (PPC), Solaris 10 and Windows XP all 32-bit Python and on RHEL 3u7 and Solaris 10 both 64-bit Python.
