If you need to adjust the xFilesFactor value for existing metrics, employ the whisper-resize.py tool:
<code>
$ sudo su -c "umask 0033; whisper-resize.py --xFilesFactor=0.0 --nobackup \
  /data/whisper/pulse/amqp-publishes-per-second.wsp 1s:5m 1m:1d 5m:28d 15m:1y" carbon
</code>

==== Init script for carbon ====

To start carbon at reboot, add the following script into the right rc level:
<code>
#! /bin/sh
# /etc/init.d/carbon

# Some things that run always
touch /var/run/carbon

GRAPHITE_HOME=/opt/graphite
CARBON_USER=www

# Carry out specific functions when asked to by the system
case "$1" in
    start)
        echo "Starting script carbon "
        su $CARBON_USER -c "cd $GRAPHITE_HOME"; su $CARBON_USR -c "$GRAPHITE_HOME/bin/carbon-cache.py start"
        ;;
    stop)
        echo "Stopping script carbon"
        su $CARBON_USER -c "cd $GRAPHITE_HOME"; su $CARBON_USR -c "$GRAPHITE_HOME/bin/carbon-cache.py stop"
        ;;
    *)
        echo "Usage: /etc/init.d/carbon {start|stop}"
        exit 1
        ;;
esac

exit 0
</code>

==== Django DB ====

http://www.boris.co/2012/02/get-graphite-run-for-django-project.html

Run
  1	# carbon
  2	cd ../../
  3	sudo ./bin/carbon-cache.py start
  4	## it will listen on 2003 port
  5	 
  6	# graphite web ui
  7	cd webapp/graphite
  8	python manage.py runserver 0.0.0.0:8000

As Graphite has an internal Django DB, here are some usefull commands:\\
First go to the Django DB home directory: search the file settings.py and go in that directory

== Create a superuser for the DB: ==
  python manage.py createsuperuser --username=joe --email=joe@example.com

== Create a basic user for the DB: ==
  python manage.py shell
  >>> from django.contrib.auth.models import User
  >>> user = User.objects.create_user('john', 'lennon@thebeatles.com', 'johnpassword')

  # At this point, user is a User object that has already been saved
  # to the database. You can continue to change its attributes
  # if you want to change other fields.
  >>> user.last_name = 'Lennon'
  >>> user.save()

== List all users defined into the DB: ==
  python manage.py shell
  Python 2.7.3 (default, Apr 14 2012, 08:58:41) [GCC] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  (InteractiveConsole)
  >>> from django.contrib.auth.models import User, Group
  >>> User.objects.filter(first_name='')
  [<User: root>, <User: default>, <User: manu>]
  >>> User.objects.filter(is_superuser='true')
  [<User: root>, <User: manu>]

== Change a user password ==
  python manage.py shell
  >>> from django.contrib.auth.models import User
  >>> u = User.objects.get(username__exact='john')
  >>> u.set_password('new password')
  >>> u.save()
