Puppet Class: watcher

Defined in:
manifests/init.pp

Overview

Class: watcher

Full description of class watcher here.

Parameters:

package_ensure

(optional) Whether the watcher api package will be installed Defaults to ‘present’

rabbit_login_method

(optional) The RabbitMQ login method. (string value) Defaults to $facts

rabbit_retry_interval

(Optional) How frequently to retry connecting with RabbitMQ. (integer value) Defaults to $facts

rabbit_retry_backoff

(Optional) How long to backoff for between retries when connecting to RabbitMQ. (integer value) Defaults to $facts

rabbit_interval_max

(Optional) Maximum interval of RabbitMQ connection retries. (integer value) Defaults to $facts

rabbit_use_ssl

(optional) Connect over SSL for RabbitMQ. Defaults to $facts

rabbit_heartbeat_rate

(optional) ow often times during the heartbeat_timeout_threshold we check the heartbeat. Defaults to $facts

rabbit_heartbeat_in_pthread

(Optional) EXPERIMENTAL: Run the health check heartbeat thread through a native python thread. By default if this option isn’t provided the health check heartbeat will inherit the execution model from the parent process. By example if the parent process have monkey patched the stdlib by using eventlet/greenlet then the heartbeat will be run through a green thread. Defaults to $facts

rabbit_ha_queues

(optional) Use HA queues in RabbitMQ (x-ha-policy: all). If you change this option, you must wipe the RabbitMQ database. Defaults to $facts

rabbit_quorum_queue

(Optional) Use quorum queues in RabbitMQ. Defaults to $facts

rabbit_transient_quorum_queue

(Optional) Use quorum queues for transients queues in RabbitMQ. Defaults to $facts

rabbit_quorum_delivery_limit

(Optional) Each time a message is rdelivered to a consumer, a counter is incremented. Once the redelivery count exceeds the delivery limit the message gets dropped or dead-lettered. Defaults to $facts

rabbit_quorum_max_memory_length

(Optional) Limit the number of messages in the quorum queue. Defaults to $facts

rabbit_quorum_max_memory_bytes

(Optional) Limit the number of memory bytes used by the quorum queue. Defaults to $facts

rabbit_enable_cancel_on_failover

(Optional) Enable x-cancel-on-ha-failover flag so that rabbitmq server will cancel and notify consumers when queue is down. Defaults to $facts

rabbit_transient_queues_ttl

(Optional) Positive integer representing duration in seconds for queue TTL (x-expires). Queues which are unused for the duration of the TTL are automatically deleted. The parameter affects only reply and fanout queues. (integer value) Min to 1 Defaults to $facts

rabbit_heartbeat_timeout_threshold

(Optional) Number of seconds after which the Rabbit broker is considered down if heartbeat’s keep-alive fails (0 disable the heartbeat). EXPERIMENTAL. (integer value) Defaults to $facts

kombu_ssl_ca_certs

(optional) SSL certification authority file (valid only if SSL enabled). Defaults to $facts

kombu_ssl_certfile

(optional) SSL cert file (valid only if SSL enabled). Defaults to $facts

kombu_ssl_keyfile

(optional) SSL key file (valid only if SSL enabled). Defaults to $facts

kombu_ssl_version

(optional) SSL version to use (valid only if SSL enabled). Valid values are TLSv1 and SSLv23. SSLv2, SSLv3, TLSv1_1, and TLSv1_2 may be available on some distributions. Defaults to $facts

kombu_reconnect_delay

(optional) How long to wait before reconnecting in response to an AMQP consumer cancel notification. Defaults to $facts

kombu_missing_consumer_retry_timeout

(optional)How long to wait a missing client beforce abandoning to send it

its replies. This value should not be longer than rpc_response_timeout.
Defaults to $facts['os_service_default']
kombu_failover_strategy

(Optional) Determines how the next RabbitMQ node is chosen in case the one we are currently connected to becomes unavailable. Takes effect only if more than one RabbitMQ node is provided in config. (string value) Defaults to $facts

kombu_compression

(optional) Possible values are: gzip, bz2. If not set compression will not be used. This option may notbe available in future versions. EXPERIMENTAL. (string value) Defaults to $facts

amqp_durable_queues

(optional) Use durable queues in AMQP. Defaults to $facts

default_transport_url

(Optional) A URL representing the messaging driver to use and its full configuration. If not set, we fall back to the rpc_backend option and driver specific configuration. Defaults to $facts

rpc_response_timeout

(Optional) Seconds to wait for a response from a call. Defaults to $facts

control_exchange

(Optional) The default exchange under which topics are scoped. May be overridden by an exchange name specified in the transport_url option. Defaults to $facts

notification_transport_url

(Optional) A URL representing the messaging driver to use for notifications and its full configuration. Transport URLs take the form:

transport://user:pass@host1:port[,hostN:portN]/virtual_host

Defaults to $facts

notification_driver

(Optional) Driver or drivers to handle sending notifications. Value can be a string or a list. Defaults to $facts

notification_topics

(Optional) AMQP topic used for OpenStack notifications Defaults to $facts

notification_retry

(Optional) The maximum number of attempts to re-sent a notification message, which failed to be delivered due to a recoverable error. Defaults to $facts.

purge_config

(optional) Whether to set only the specified config options in the watcher config. Defaults to false.
