Question #178172 on Graphite changed:
https://answers.launchpad.net/graphite/+question/178172

cbrinley posted a new comment:
Hi Sanjaya,
This just means django can't find the graphite settings module. That is its
not defined as an environmental variable or in the apache config.
Attached is doc on this. A typical setting looks like this: export
DJANGO_SETTINGS_MODULE=graphite.settings
Your setup may differ so please consult the django documentation.
