RabbitMQ queue management tools

Synopsis

rabbitmq-queues[-q] [-s] [-l] [-n node] [-t timeout] command [command_options]

Description

rabbitmq-queues is a command line tool that provides commands used to manage queues, mainly member handling for quorum queues. See the RabbitMQ quorum queues guide and RabbitMQ classic mirrored queues guide to learn more about queue types in RabbitMQ.

Options

-n node

Default node is "rabbit@target-hostname", where target-hostname is the local host. On a host named "myserver.example.com", the node name will usually be "rabbit@myserver" (unless RABBITMQ_NODENAME has been overridden). The output of "hostname -s" is usually the correct suffix to use after the "@" sign. See rabbitmq-server(8) for details of configuring a RabbitMQ node.

-q, --quiet

Quiet output mode is selected. Informational messages are reduced when quiet mode is in effect.

-s, --silent

Silent output mode is selected. Informational messages are reduced and table headers are suppressed when silent mode is in effect.

-t timeout, --timeout timeout

Operation timeout in seconds. Not all commands support timeouts. Default is infinity.

-l, --longnames

Must be specified when the cluster is configured to use long (FQDN) node names. To learn more, see the RabbitMQ Clustering guide

--erlang-cookie cookie

Shared secret to use to authenticate to the target node. Prefer using a local file or the RABBITMQ_ERLANG_COOKIE environment variable instead of specifying this option on the command line. To learn more, see the RabbitMQ CLI Tools guide

Commands

help

Displays general help and commands supported by rabbitmq-queues.

Cluster

grow node selector --vhost-pattern pattern --queue-pattern pattern --errors-only

Adds a new replica on the given node for all or a half of matching quorum queues.

Supported selector values are:

all

Selects all quorum queues

even

Selects quorum queues with an even number of replicas

Example:

rabbitmq-queues grow "rabbit@newhost" "all" --vhost-pattern "a-vhost" --queue-pattern ".*"

rebalance type --vhost-pattern pattern --queue-pattern pattern

Rebalances queue master replicas across cluster nodes.

Supported type values are:

all

All queue types

quorum

Only quorum queues

classic

Only classic queues

Example:

rabbitmq-queues rebalance "all" --vhost-pattern "a-vhost" --queue-pattern ".*"

shrink node

Shrinks quorum queue clusters by removing any members (replicas) on the given node.

Example:

rabbitmq-queues shrink "rabbit@decomissioned-node"

Replication

add_member queue node --vhost virtual-host

Adds a quorum queue member (replica) on the given node.

Example:

rabbitmq-queues add_member --vhost "a-vhost" "a-queue" "rabbit@new-node"

delete_member queue node --vhost virtual-host

Removes a quorum queue member (replica) on the given node.

Example:

rabbitmq-queues delete_member --vhost "a-vhost" "a-queue" "rabbit@decomissioned-node"

Queues

quorum_status queue --vhost virtual-host

Displays quorum status of a quorum queue.

Example:

rabbitmq-queues quorum_status --vhost "a-vhost" "a-queue"
