    Graphite charts without the Graphite app

    Graphite is kind of insane to setup, in particular all the nonsense around Cairo and PyCairo. What. A. Pain. But the back-end (Carbon and Whisper) is easy to setup and works as advertised.

    So I decided to see if I can use D3 to draw SVG charts directly from the Whisper files generated by the Graphite back-end (Carbon).

    Famout last words.

    But it worked. Good enough for playing with charts, and an awesome JavaScript learning experience. (Yes, I optimize my free time for that)

    So skip the Graphite Web app and get Carbon and Whisper installed:

    $ sudo pip install whisper
$ sudo pip install carbon
$ cp /opt/graphite/conf/carbon.conf.example /opt/graphite/conf/carbon.conf
$ cp /opt/graphite/conf/storage-schemas.conf.example /opt/graphite/conf/storage-schemas.conf

    Fire up Carbon and start collecting data:

    $ /opt/graphite/bin/carbon-cache.py start

    Now run the Web server:

    $ npm start $ open localhost:8080

    If your machine stores Whisper files in any other directory, you need to tell the server where to look by setting the environment variable GRAPHITE_STORAGE. The default path is /opt/graphite/storage.

    Enjoy.

    Note This is an experiment more than anything. Some functions are implemented, most not, neither are date ranges. But if you like to hack on it, be my guest.
