A python rrdtool facade - work in progress
The purpose of thie rrdtool-cli facade library is to make the configuration of rrd creation, update and graph easier and faster.
import pyrrdtool as rrd
db = rrd.Database.load('tests/samples/mini.rrd')
speed = rrd.Variable(db, 'speed')
g = rrd.Graph([rrd.DEF.from_variable(speed)],
[rrd.AREA.from_variable(speed, {'color': 'ffffcc'}),
rrd.LINE.from_variable(speed, {'width': 2, 'color': 'ccff33'})])
png_binary = g.draw()By enabling the user to create definitions of rrdatabases, datasouces and graphs that are modular and reusable for creating, updating and graphing a wide variety of graphs, easily and with peace of mind.
Along with a python API to call rrdtool features such as create, update, fetch and graph that is easier and faster to use, with default and automatic cli options generation.
It should be easy to provide the graphing feature as a REST API that return graph images binaries (see rrdli).

Because writing this library is also an in-depth learning of rrdtool, the code should be commented nicely to promote the understanding of what's happening
