access-network | string

The IP address and netmask of the 'access' network (e.g. 192.168.0.0/24) . This network will be used for access to RabbitMQ messaging services.

ceph-osd-replication-count | int

Default: 3

This value dictates the number of replicas ceph must make of any object it stores within the rabbitmq rbd pool. Of course, this only applies if using Ceph as a backend store. Note that once the rabbitmq rbd pool has been created, changing this value will not have any effect (although it can be changed in ceph by manually configuring your ceph cluster).

cluster-network | string

The IP address and netmask of the 'cluster' network (e.g. 192.168.0.0/24) . This network will be used for RabbitMQ to cluster.

cluster-partition-handling | string

Default: autoheal

RabbitMQ offers three ways to deal with network partitions automatically. Available modes: . ignore - Your network is reliable. All your nodes are in a rack, connected with a switch, and that switch is also the route to the outside world. You don't want to run any risk of any of your cluster shutting down if any other part of it fails (or you have a two node cluster). . pause_minority - Your network is maybe less reliable. You have clustered across 3 AZs in EC2, and you assume that only one AZ will fail at once. In that scenario you want the remaining two AZs to continue working and the nodes from the failed AZ to rejoin automatically and without fuss when the AZ comes back. . autoheal - Your network may not be reliable. You are more concerned with continuity of service than with data integrity. You may have a two node cluster. . For more information see http://www.rabbitmq.com/partitions.html

connection-backlog | int

Overrides the size of the connection backlog maintained by the server. Environments with large numbers of clients will want to set this value higher than the default (default value varies with rabbtimq version, see https://www.rabbitmq.com/networking.html for more info).

cron-timeout | int

Default: 300

Run a command with a time limit specified in seconds in cron. This timeout will govern to the rabbitmq stats capture, and that once the timeout is reached a SIGINT is sent to the program, if it doesn't exits before 10 seconds a SIGKILL is sent.

erl-vm-io-thread-multiplier | int

Multiplier used to calculate the number of threads used in the erl vm worker thread pool using the number of CPU cores extant in the host system. The upstream docs recommend that this multiplier be > 12 per core - we use 24 as default so that we end up with roughly the same as current rabbitmq package defaults and that is what is used internally to the charm if no value is set here. Also, if this value is left unset and this application is running inside a container, the number of threads will be capped based on a maximum of 2 cores.

ha-bindiface | string

Default: eth0

Default network interface on which HA cluster will bind to communication with the other members of the HA Cluster.

ha-mcastport | int

Default: 5406

Default multicast port number that will be used to communicate between HA Cluster nodes.

ha-vip-only | boolean

By default, without pairing with hacluster charm, rabbitmq will deploy in active/active/active... HA. When pairied with hacluster charm, it will deploy as active/passive. By enabling this option, pairing with hacluster charm will keep rabbit in active/active setup, but in addition it will deploy a VIP that can be used by services that cannot work with mutiple AMQPs (like Glance in pre-Icehouse).

harden | string

Apply system hardening. Supports a space-delimited list of modules to run. Supported modules currently include os, ssh, apache and mysql.

key | string

Key ID to import to the apt keyring to support use with arbitary source configuration from outside of Launchpad archives or PPA's.

known-wait | int

Default: 30

Known wait along with modulo nodes is used to help avoid restart collisions. Known wait is the amount of time between one node executing an operation and another. On slower hardware this value may need to be larger than the default of 30 seconds.

management_plugin | boolean

Enable the management plugin.

max-cluster-tries | int

Default: 3

Number of tries to cluster with other units before giving up and throwing a hook error.

min-cluster-size | int

Minimum number of units expected to exist before charm will attempt to form a rabbitmq cluster.

mirroring-queues | boolean

Default: True

When set to True the 'ha-mode: all' policy is applied to all the exchanges that match the expression '^(?!amq\.).*'

modulo-nodes | int

This config option is rarely required but is provided for fine tuning, it is safe to leave unset. Modulo nodes is used to help avoid restart collisions as well as distribute load on the cloud at larger scale. During restarts and cluster joins rabbitmq needs to execute these operations serially. By setting modulo-nodes to the size of the cluster and known-wait to a reasonable value, the charm will distribute the operations serially. If this value is unset, the charm will check min-cluster-size or else finally default to the size of the cluster based on peer relations. Setting this value to 0 will execute operations with no wait time. Setting this value to less than the cluster size will distribute load but may lead to restart collisions.

nagios_context | string

Default: juju

Used by the nrpe-external-master subordinate charm. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: . juju-myservice-0 . If you're running multiple environments with the same services in them this allows you to differentiate between them.

nagios_servicegroups | string

A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup.

notification-ttl | int

Default: 3600000

TTL in MS for notification queues in the openstack vhost. Defaults to 1 hour, but can be tuned up or down depending on deployment requirements. This ensures that any un-consumed notifications don't build up over time, causing disk capacity issues.

prefer-ipv6 | boolean

If True enables IPv6 support. The charm will expect network interfaces to be configured with an IPv6 address. If set to False (default) IPv4 is expected. . NOTE: these charms do not currently support IPv6 privacy extension. In order for this charm to function correctly, the privacy extension must be disabled and a non-temporary address must be configured/available on your network interface.

queue_thresholds | string

Default: [['\*', '\*', 100, 200]]

List of RabbitMQ queue size check thresholds. Interpreted as YAML in format [<vhost>, <queue>, <warn>, <crit>] Per-queue thresholds can be expressed as a multi-line YAML array: - ['/', 'queue1', 10, 20] - ['/', 'queue2', 200, 300] Or as a list of lists: [['/', 'queue1', 10, 20], ['/', 'queue2', 200, 300]] Wildcards '*' are accepted to monitor all vhosts and/or queues. In case of multiple matches, only the first will apply: wildcards should therefore be used last in order to avoid unexpected behavior.

rbd-name | string

Default: rabbitmq1

The name that will be used to create the Ceph's RBD image with. If the image name exists in Ceph, it will be re-used and the data will be overwritten.

rbd-size | string

Default: 5G

Default rbd storage size to create when setting up block storage. This value should be specified in GB (e.g. 100G).

source | string

Optional configuration to support use of additional sources such as: . - ppa:myteam/ppa - cloud:xenial-proposed/ocata - http://my.archive.com/ubuntu main . The last option should be used in conjunction with the key configuration option. . Changing the source option on already deployed service/application will trigger the upgrade.

ssl | string

Default: off

Enable SSL connections on rabbitmq, valid values are 'off', 'on', 'only'. If ssl_key, ssl_cert, ssl_ca are provided then then those values will be used. Otherwise the service will act as its own certificate authority and pass its ca cert to clients. For HA or clustered rabbits ssl key/cert must be provided.

ssl_ca | string

Certificate authority cert that the cert. Optional if the ssl_cert is signed by a ca recognized by the os. Format is base64 PEM (concatenated certs if needed).

ssl_cert | string

X.509 certificate in base64 PEM format (i.e. starts with "-----BEGIN CERTIFICATE-----")

ssl_enabled | boolean

(DEPRECATED see 'ssl' config option.) enable SSL

ssl_key | string

Private unencrypted key in base64 PEM format (i.e. starts with "-----BEGIN RSA PRIVATE KEY-----")

ssl_port | int

Default: 5671

SSL port

stats_cron_schedule | string

Default: */5 * * * *

Cron schedule used to generate rabbitmq stats. To disable, either unset this config option or set it to an empty string ('').

use-syslog | boolean

If True, services that support it will log to syslog instead of their normal log location.

vip | string

Virtual IP to use to front rabbitmq in ha configuration

vip_cidr | int

Default: 24

Netmask that will be used for the Virtual IP

vip_iface | string

Default: eth0

Network Interface where to place the Virtual IP
