# == Class: ceilometer::agent::polling
#
# Installs/configures the ceilometer polling agent
#
# === Parameters:
#
# [*enabled*]
# (Optional) Should the service be enabled.
# Defaults to true.
#
# [*manage_service*]
# (Optional) Whether the service should be managed by Puppet.
# Defaults to true.
#
# [*package_ensure*]
# (Optional) ensure state for package.
# Defaults to 'present'
#
# [*central_namespace*]
# (Optional) Use central namespace for polling agent.
# Defaults to true.
#
# [*compute_namespace*]
# (Optional) Use compute namespace for polling agent.
# Defaults to true.
#
# [*ipmi_namespace*]
# (Optional) Use ipmi namespace for polling agent.
# Defaults to true.
#
# [*instance_discovery_method*]
# (Optional) method to discovery instances running on compute node
# Defaults to $::os_service_default
# * naive: poll nova to get all instances
# * workload_partitioning: poll nova to get instances of the compute
# * libvirt_metadata: get instances from libvirt metadata
# but without instance metadata (recommended for Gnocchi backend).
#
# [*manage_polling*]
# (Optional) Whether to manage polling.yaml
# Defaults to false
#
# [*polling_interval*]
# (Optional) Number of seconds between polling cycle
# Defaults to 600 seconds, used only if manage_polling is true.
#
# [*polling_meters*]
# (Optional) Array of strings with meters to add to
# the polling.yaml file, used only if manage_polling is true.
# Defaults to $::ceilometer::params::polling_meters
#
# [*polling_config*]
# (Optional) A hash of the polling.yaml configuration.
# This is used only if manage_polling is true.
# Defaults to undef
#
# DEPRECATED PARAMETERS
#
# [*coordination_url*]
