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 and the general
RabbitMQ 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
- 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:
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:
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"
peek
queue position--vhost
virtual-host--timeout
-
Displays the details of a message at the given position in the queue. This command is currently only supported by quorum queues.
Example:
rabbitmq-queues peek --vhost "a-vhost" "a-queue" "1"
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
