The python-rrdtool provides an interface to rrdtool, the wonderful graphing and logging utility. This wrapper implementation has worked from the scratch (without SWIG), and it's under LGPL. The bindings are based on the code of the original Python 2 bindings module for rrdtool by Hye-Shik Chang and are now shipped with the RRDtool distribution. This project is maintained separately to provide a more pythonic way to install those bindings via PyPI.
