SVG graphs from Whisper files

Graphite Charts Without the Graphite App

Graphite without Graphite

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.

Something went wrong with that request. Please try again.
