+#####################################
+# Set this to a long, random unique string to use as a secret key for this

+# CRSF middleware, cookie storage, etc. This should be set identically among
+# instances if used behind a load balancer.

+# memcached entirely.
+#
+# You should not use the loopback address (127.0.0.1) here if using clustering
+# as every webapp in the cluster should use the exact same values to prevent
+# unneeded cache misses. Set to [] to disable caching of images and fetched data

+# If you want to further customize the ldap connection options you should

+# For example:
+#
+#import ldap

+###############################
+# Authorization for Dashboard #
+###############################
+# By default, there is no security on dashboards - any user can add, change or delete them.
+# This section provides 3 different authorization models, of varying strictness.
+
+# If set to True, users must be logged in to save or delete dashboards. Defaults to False
+#DASHBOARD_REQUIRE_AUTHENTICATION = True
+
+# If set to the name of a user group, dashboards can be saved and deleted by any user in this
+# group.  Groups can be set in the Django Admin app, or in LDAP.  Defaults to None.
+# NOTE: Ignored if DASHBOARD_REQUIRE_AUTHENTICATION is not set
+#DASHBOARD_REQUIRE_EDIT_GROUP = 'dashboard-editors-group'
+
+# If set to True, dashboards can be saved or deleted by any user having the appropriate
+# (change or delete) permission (as set in the Django Admin app).  Defaults to False
+# NOTE: Ignored if DASHBOARD_REQUIRE_AUTHENTICATION is not set
+#DASHBOARD_REQUIRE_PERMISSIONS = True

+##########################
+# Database Configuration #
+##########################
+# By default sqlite is used. If you cluster multiple webapps you will need
+# to setup an external database (such as MySQL) and configure all of the webapp
+# instances to use the same database. Note that this database is only used to store
+# Django models such as saved graphs, dashboards, user preferences, etc.
+# Metric data is not stored here.
+#
+# DO NOT FORGET TO RUN 'django-admin.py syncdb' AFTER SETTING UP A NEW DATABASE
+#
+# The following built-in database engines are available:
+#  django.db.backends.postgresql_psycopg2
+#  django.db.backends.mysql
+#  django.db.backends.sqlite3
+#  django.db.backends.oracle
+#
+# The default is 'django.db.backends.sqlite3' with file 'graphite.db'
+# located in STORAGE_DIR
+#
+DATABASES = {
+    'default': {
+        'NAME': '/home/www-data/graphite/storage/graphite.db',

+#########################
+# Cluster Configuration #
+#########################
+# (To avoid excessive DNS lookups you want to stick to using IP addresses only in this entire section)
+#
+# This should list the IP address (and optionally port) of the webapp on each
+# remote server in the cluster. These servers must each have local access to
+# metric data. Note that the first server to return a match for a query will be
+# used.
+#CLUSTER_SERVERS = ["10.0.2.2:80", "10.0.2.3:80"]
+
+## These are timeout values (in seconds) for requests to remote webapps
+#REMOTE_FIND_TIMEOUT = 3.0             # Timeout for metric find requests
+#REMOTE_FETCH_TIMEOUT = 6.0            # Timeout to fetch series data
+#REMOTE_RETRY_DELAY = 60.0             # Time before retrying a failed remote webapp
+#REMOTE_READER_CACHE_SIZE_LIMIT = 1000 # Maximum number of remote URL queries to cache
+#FIND_CACHE_DURATION = 300             # Time to cache remote metric find results
+# If the query doesn't fall entirely within the FIND_TOLERANCE window
+# we disregard the window. This prevents unnecessary remote fetches
+# caused when carbon's cache skews node.intervals, giving the appearance
+# remote systems have data we don't have locally, which we probably do.
+#FIND_TOLERANCE = 2 * FIND_CACHE_DURATION
+
+## Remote rendering settings
+# Set to True to enable rendering of Graphs on a remote webapp
+#REMOTE_RENDERING = True
+# List of IP (and optionally port) of the webapp on each remote server that
+# will be used for rendering. Note that each rendering host should have local
+# access to metric data or should have CLUSTER_SERVERS configured
+#RENDERING_HOSTS = []
+#REMOTE_RENDER_CONNECT_TIMEOUT = 1.0
+
+# If you are running multiple carbon-caches on this machine (typically behind a relay using
+# consistent hashing), you'll need to list the ip address, cache query port, and instance name of each carbon-cache
+# instance on the local machine (NOT every carbon-cache in the entire cluster). The default cache query port is 7002
+# and a common scheme is to use 7102 for instance b, 7202 for instance c, etc.
+#
+# You *should* use 127.0.0.1 here in most cases
+#CARBONLINK_HOSTS = ["127.0.0.1:7002:a", "127.0.0.1:7102:b", "127.0.0.1:7202:c"]
+#CARBONLINK_TIMEOUT = 1.0
+#CARBONLINK_RETRY_DELAY = 15 # Seconds to blacklist a failed remote server
+
+# A "keyfunc" is a user-defined python function that is given a metric name
+# and returns a string that should be used when hashing the metric name.
+# This is important when your hashing has to respect certain metric groupings.
+#CARBONLINK_HASHING_KEYFUNC = "/opt/graphite/bin/keyfuncs.py:my_keyfunc"
+
+# Prefix set in carbon for the carbon specific metrics.  Default in carbon is 'carbon'
+#CARBON_METRIC_PREFIX='carbon'
+
+# The replication factor to use with consistent hashing
+# This should usually match the value configured in Carbon
+#REPLICATION_FACTOR = 1
+
+# How often should render.datalib.fetch() retry to get remote data
+# MAX_FETCH_RETRIES = 2
