Ansible - Graphite: Scalable Realtime Graphing

This Ansible playbook will install graphite via pip in its default location '/opt/graphite'

To run this playbook.

1. clone the repo
2. modify the hosts file to reflect the server you want to install Graphite on
3. ignore ssh's known hosts file

• export ANSIBLE_HOST_KEY_CHECKING=False

4. run ansible-playbook -i hosts playbook.yml

• You can modify the user Ansible uses by adding extra-vars ansible-playbook -i hosts playbook.yml --extra-vars ssh_user=ec2-user

5. In ~4 minutes you should have a running Graphite server!

What you need to change

Secrets

Change graphite_secret_key under roles/graphite/defaults/main.yml to something unique for your graphite instance!

Django

Change graphite_django_admin_media under roles/graphite/defaults/main.yml to the path of your django admin media

    # XXX In order for the django admin site media to work you
    # must change @DJANGO_ROOT@ to be the path to your django
    # installation, which is probably something like:

    Alias /media/ "/usr/local/lib/python2.7/dist-packages/django/contrib/admin/static/admin/"
    # or 
    #Alias /media/ "/usr/lib/python2.6/site-packages/django/contrib/admin/media/"
