RRD (round-robin database) data visualization widgets.

You can use the widgets in this module to analyze your data from rrdtool (usually collected by another tool like collectd or ganglia or.. well, there are many).

Widgets, by and large, need to either be given a rrd_filenames list that tells them what rrd files to graph explicitly, or an rrd_directories list that tells them where to look for rrd files (they'll graph every file they find in the directory).

Take a look at the file for inspiration.

Sampling tw2.rrd in the WidgetBrowser

The best way to scope out tw2.rrd is to load its widgets in the tw2.devtools WidgetBrowser. To see the source code that configures them, check out tw2.rrd/tw2/rrd/

To give it a try you'll need git, python, and virtualenvwrapper. Run:

$ git clone git://
$ cd tw2.rrd
$ mkvirtualenv tw2.rrd
(tw2.rrd) $ pip install tw2.devtools
(tw2.rrd) $ python develop
(tw2.rrd) $ paster tw2.browser

...and browse to http://localhost:8000/ to check it out.
