RRDTool is a neat utility for collecting and graphing statistics such as server loads or network traffic. There are two main modules for interfacing with RRDTool files within python; rrdpython and pyrrd.
rrdpython is the basic bindings of the rrdtool library within python. The API is very familiar for people who program in C or use the command line tools which for me is both so it works well. However if you were expecting a “pythonic” API you will be disappointed. As there is the direct binding, you have to have either a pre-compiled module or compile it yourself with librrd-dev package installed. Depending on your setup this could be trivial or a real pain.
Well, the problem is its not pure python. The hooks are there for it (in backend.py) for it to be implemented in python but it falls back to using the external method, and external method is a bunch of Popen calls. pyrrd also does not
support the full set of rrdtool commands.
My intention is to keep using rrdpython despite the compile hassle and possibly even use a fancier graph setup such as High Charts though there is a problem with their license for me.
