Description of common configuration options

Configuration option = Default value	Description
[DEFAULT]
host = localhost	(StrOpt) Name of this node, which must be valid in an AMQP key. Can be an opaque identifier. For ZeroMQ only, must be a valid host name, FQDN, or IP address.
http_timeout = 600	(IntOpt) Timeout seconds for HTTP requests. Set it to None to disable timeout.
memcached_servers = None	(ListOpt) Memcached servers or None for in process cache.
notification_workers = 1	(IntOpt) Number of workers for notification service. A single notification agent is enabled by default.
polling_namespaces = ['compute', 'central']	(MultiChoicesOpt) Polling namespace(s) to be used while resource polling
pollster_list = []	(MultiChoicesOpt) List of pollsters (or wildcard templates) to be used while polling
rootwrap_config = /etc/ceilometer/rootwrap.conf	(StrOpt) Path to the rootwrap configuration file touse for running commands as root
shuffle_time_before_polling_task = 0	(IntOpt) To reduce large requests at same time to Nova or other components from different compute agents, shuffle start time of polling task.
sql_expire_samples_only = False	(BoolOpt) Indicates if expirer expires only samples. If set true, expired samples will be deleted, but residual resource and meter definition data will remain.
[compute]
workload_partitioning = False	(BoolOpt) Enable work-load partitioning, allowing multiple compute agents to be run simultaneously.
[coordination]
backend_url = None	(StrOpt) The backend URL to use for distributed coordination. If left empty, per-deployment central agent and per-host compute agent won't do workload partitioning and will only function correctly if a single instance of that service is running.
check_watchers = 10.0	(FloatOpt) Number of seconds between checks to see if group membership has changed
heartbeat = 1.0	(FloatOpt) Number of seconds between heartbeats for distributed coordination.
[keystone_authtoken]
memcached_servers = None	(ListOpt) Optionally specify a list of memcached server(s) to use for caching. If left undefined, tokens will instead be cached in-process.
[polling]
partitioning_group_prefix = None	(StrOpt) Work-load partitioning group prefix. Use only if you want to run multiple polling agents with different config files. For each sub-group of the agent pool with the same partitioning_group_prefix a disjoint subset of pollsters should be loaded.
