Question #269965 on Graphite changed:
https://answers.launchpad.net/graphite/+question/269965
Status: Needs information => Open
Yue Zhang gave more information on the question:
Actually I have tried a lot of times but can not regenerate the "Protocol
wrong type for socket" but again got this every time:
[03/Aug/2015 21:07:06]"GET /render/?width=1041&height=542&_salt=1438661217.502
HTTP/1.1" 200 4
- Broken pipe from ('127.0.0.1', 52538)
There are nothing special about my setup, I use a Mac 10.10 and totally
follow the documentation to follow the initialization, everything is
default except the "CARBONLINK_HASHING_KEYFUNC" in local_settings.py,
which I set it to "None". And I followed this link to get started:
http://graphite.wikidot.com/quickstart-guide.
Below is my whole local_settings.py:
## Graphite local_settings.py
# Edit this file to customize the default Graphite webapp settings
#
# Additional customizations to Django settings can be added to this file as well
#####################################
# General Configuration #
#####################################
# Set this to a long, random unique string to use as a secret key for this
# install. This key is used for salting of hashes used in auth tokens,
# CRSF middleware, cookie storage, etc. This should be set identically among
# instances if used behind a load balancer.
SECRET_KEY = 'UNSAFE_DEFAULT'
# In Django 1.5+ set this to the list of hosts your graphite instances is
# accessible as. See:
# https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-ALLOWED_HOSTS
ALLOWED_HOSTS = [ '*' ]
# Set your local timezone (Django's default is America/Chicago)
# If your graphs appear to be offset by a couple hours then this probably
# needs to be explicitly set to your local timezone.
TIME_ZONE = 'America/Los_Angeles'
# Override this to provide documentation specific to your Graphite deployment
DOCUMENTATION_URL = "http://graphite.readthedocs.org/";
# Metric data and graphs are cached for one minute by default

# If using RRD files and rrdcached, set to the address or socket of the daemon
FLUSHRRDCACHED = 'unix:/var/run/rrdcached.sock'
# This lists the memcached servers that will be used by this webapp.
# If you have a cluster of webapps you should ensure all of them
# have the *exact* same value for this setting. That will maximize cache
# efficiency. Setting MEMCACHE_HOSTS to be empty will turn off use of
# 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
MEMCACHE_HOSTS = ['10.10.10.10:11211', '10.10.10.11:11211', '10.10.10.12:11211']
DEFAULT_CACHE_DURATION = 60 # Cache images and data for 1 minute

#####################################

# Change only GRAPHITE_ROOT if your install is merely shifted from /opt/graphite
# to somewhere else

#####################################
# Authentication Configuration #
#####################################
## LDAP / ActiveDirectory authentication setup
USE_LDAP_AUTH = True
LDAP_SERVER = "ldap.mycompany.com"
LDAP_PORT = 389
LDAP_USE_TLS = False
# OR
LDAP_URI = "ldaps://ldap.mycompany.com:636"

LDAP_BASE_PASS = "readonly_account_password"
LDAP_USER_QUERY = "(username=%s)" #For Active Directory use
"(sAMAccountName=%s)"
#
# If you want to further customize the ldap connection options you should
# directly use ldap.set_option to set the ldap module's global options.
# For example:
#
#import ldap
#ldap.set_option(ldap.OPT_X_TLS_REQUIRE_CERT, ldap.OPT_X_TLS_ALLOW) # Use
ldap.OPT_X_TLS_DEMAND to force TLS
#ldap.set_option(ldap.OPT_REFERRALS, 0) # Enable for Active Directory
#ldap.set_option(ldap.OPT_X_TLS_CACERTDIR, "/etc/ssl/ca")
#ldap.set_option(ldap.OPT_X_TLS_CERTFILE, "/etc/ssl/mycert.pem")
#ldap.set_option(ldap.OPT_X_TLS_KEYFILE, "/etc/ssl/mykey.pem")
#ldap.set_option(ldap.OPT_DEBUG_LEVEL, 65535) # To enable verbose debugging
# See http://www.python-ldap.org/ for further details on these options.
## REMOTE_USER authentication. See:
https://docs.djangoproject.com/en/dev/howto/auth-remote-user/
USE_REMOTE_USER_AUTHENTICATION = True
# Override the URL for the login link (e.g. for django_openid_auth)
LOGIN_URL = '/account/login'
###############################
# 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
#

#########################
# 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_EXCLUDE_LOCAL = False # Try to detect when a cluster server is
localhost and don't forward queries
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"
CARBONLINK_HASHING_KEYFUNC = None
# 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
