RABBITMQ-QUEUES(8)

NAME
rabbitmq-queues - 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, for example, grow, shrink or rebalance replicas of replicated queue types. See the RabbitMQ quorum queues guide: https://www.rabbitmq.com/quorum-queues.html and the general RabbitMQ queues guide: https://www.rabbitmq.com/queues.html 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: https://www.rabbitmq.com/clustering.html

--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: https://www.rabbitmq.com/cli.html

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 leader 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"

check_if_node_is_mirror_sync_critical

    Health check that exits with a non-zero code if there are classic mirrored queues without online synchronised mirrors (queues that would potentially lose data if the target node is shut down).

    Example:
        rabbitmq-queues check_if_node_is_mirror_sync_critical

check_if_node_is_quorum_critical

    Health check that exits with a non-zero code if there are queues with minimum online quorum (queues that would lose their quorum if the target node is shut down).

    Example:
        rabbitmq-queues check_if_node_is_quorum_critical
