        # You can swap out the engine for MySQL easily by changing this value
        # to ``django.db.backends.mysql`` or to PostgreSQL with
        # ``django.db.backends.postgresql_psycopg2``

        # If you change this, you'll also need to install the appropriate python
        # package: psycopg2 (Postgres) or mysql-python
        'ENGINE': 'django.db.backends.postgresql_psycopg2',

        'NAME': '$DB_NAME',

# If you're expecting any kind of real traffic on Sentry, we highly recommend
# configuring the CACHES and Redis settings

###########
## CACHE ##
###########

# You'll need to install the required dependencies for Memcached:
#   pip install python-memcached
#
# CACHES = {
#     'default': {
#         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
#         'LOCATION': ['127.0.0.1:11211'],
#     }
# }

###########
## Queue ##
###########

# See http://sentry.readthedocs.org/en/latest/queue/index.html for more
# information on configuring your queue broker and workers. Sentry relies
# on a Python framework called Celery to manage queues.

# You can enable queueing of jobs by turning off the always eager setting:
CELERY_ALWAYS_EAGER = False
BROKER_URL = 'redis://localhost:6379/1'

####################
## Update Buffers ##
####################

# Buffers (combined with queueing) act as an intermediate layer between the
# database and the storage API. They will greatly improve efficiency on large
# numbers of the same events being sent to the API in a short amount of time.
# (read: if you send any kind of real data to Sentry, you should enable buffers)

# You'll need to install the required dependencies for Redis buffers:
#   pip install redis hiredis nydus
#
#SENTRY_BUFFER = 'sentry.buffer.redis.RedisBuffer'
#SENTRY_REDIS_OPTIONS = {
#    'hosts': {
#        0: {
#             'host': 'localhost',
#             'port': 6379,
#         }
#     }
# }

## Web Server ##
################

# You MUST configure the absolute URI root for Sentry:
SENTRY_URL_PREFIX = '$HOSTNAME'  # No trailing slash!

# If you're using a reverse proxy, you should enable the X-Forwarded-Proto
# and X-Forwarded-Host headers, and uncomment the following settings
# SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
# USE_X_FORWARDED_HOST = True

SENTRY_WEB_HOST = '0.0.0.0'
SENTRY_WEB_PORT = 9000
SENTRY_WEB_OPTIONS = {
    'workers': 3,  # the number of gunicorn workers
    'limit_request_line': 0,  # required for raven-js
    'secure_scheme_headers': {'X-FORWARDED-PROTO': 'https'},
}
