The default polling interval was updated from 600 to 300 in ceilometer itself[1] but the default value in the polling class wasn't updated. This updates the default value in our module so that we use the value consistent with what is maintained in ceilometer repo.

|
|
# (Optional) Should the service be enabled.
|
|
# Defaults to true.
|
|
#
|
|

|
# Defaults to 'present'
|
|
#
|
|
# [*manage_user*]
|
|
# (Optional) Should the system user should be managed. When this flag is
|
|
# true then the class ensures the ceilometer user belongs to nova/libvirt
|
|
# group.
|
|
# Defaults to true.
|
|
#
|
|
# [*central_namespace*]
|
|
# (Optional) Use central namespace for polling agent.

|
|
# Defaults to $facts['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).
|
|
#
|
|
# [*resource_update_interval*]
|
|
# (Optional) New instances will be discovered periodically based on this
|
|
# option (in seconds).

|
|
# Defaults to $facts['os_service_default'].
|
|
#
|
|
# [*manage_polling*]
|
|
# (Optional) Whether to manage polling.yaml
|
|
# Defaults to false
|
|
#
|
|
# [*polling_interval*]
|
|
# (Optional) Number of seconds between polling cycle

|
# (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
|
|
#
|
|
# [*batch_size*]
|
|
# (Optional) Batch size of samples to send to notification agent.
|
|
# Defaults to $facts['os_service_default']
|
|
#
|
|
# [*tenant_name_discovery*]
|
|
# (optional) Identify user and project names from polled metrics.
|
|
# Defaults to $facts['os_service_default'].
