RABBITMQCTL(8) BSD System Manager's Manual RABBITMQCTL(8) NAME rabbitmqctl — command line for managing a RabbitMQ broker SYNOPSIS rabbitmqctl [-q] [-l] [-n node] [-t timeout] command [command_options] DESCRIPTION RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ Server is a robust and scalable implementation of an AMQP broker. rabbitmqctl is a command line tool for managing a RabbitMQ broker. It performs all actions by connecting to one of the broker's nodes. Diagnostic information is displayed if the broker was not running, could not be reached, or rejected the connection due to mismatching Erlang cookies. OPTIONS -n node Default node is "rabbit@server", where server is the local host. On a host named "myserver.example.com", the node name of the Rab‐ bitMQ Erlang node will usually be "rabbit@myserver" (unless RABBITMQ_NODENAME has been set to some non-default value at bro‐ ker startup time). The output of "hostname -s" is usually the correct suffix to use after the "@" sign. See rabbitmq-server(8) for details of configuring the RabbitMQ broker. -q, --quiet Quiet output mode is selected. Informational messages are sup‐ pressed when quiet mode is in effect. --dry-run Do not run the command. Only print information message. -t timeout, --timeout timeout Operation timeout in seconds. Only applicable to "list" com‐ mands. Default is infinity. -l, --longnames Use longnames for erlang distribution. If RabbitMQ broker uses long node names for erlang distribution, the option must be spec‐ ified. --erlang-cookie cookie Erlang distribution cookie. If RabbitMQ node is using a custom erlang cookie value, the cookie value must be set vith this parameter. COMMANDS help [-l] [command_name] Prints usage for all available commands. -l, --list-commands List command usages only, without parameter explanation. command_name Prints usage for the specified command. Application Management force_reset Forcefully returns a RabbitMQ node to its virgin state. The force_reset command differs from reset in that it resets the node unconditionally, regardless of the current management data‐ base state and cluster configuration. It should only be used as a last resort if the database or cluster configuration has been corrupted. For reset and force_reset to succeed the RabbitMQ application must have been stopped, e.g. with stop_app. For example, to reset the RabbitMQ node: rabbitmqctl force_reset hipe_compile directory Performs HiPE-compilation and caches resulting .beam-files in the given directory. Parent directories are created if necessary. Any existing .beam files from the directory are automatically deleted prior to com‐ pilation. To use this precompiled files, you should set RABBITMQ_SERVER_CODE_PATH environment variable to directory spec‐ ified in hipe_compile invokation. For example, to HiPE-compile modules and store them to /tmp/rabbit-hipe/ebin directory: rabbitmqctl hipe_compile /tmp/rabbit-hipe/ebin reset Returns a RabbitMQ node to its virgin state. Removes the node from any cluster it belongs to, removes all data from the management database, such as configured users and vhosts, and deletes all persistent messages. For reset and force_reset to succeed the RabbitMQ application must have been stopped, e.g. with stop_app. For example, to resets the RabbitMQ node: rabbitmqctl reset rotate_logs Instructs the RabbitMQ node to perform internal log rotation. Log rotation is performed according to lager settings specified in configuration file. Note that there is no need to call this command in case of exter‐ nal log rotation (e.g. from logrotate(8)), because lager detects renames and automatically reopens log files. For example, this command starts internal log rotation process: rabbitmqctl rotate_logs Rotation is performed asynchronously, so there is no guarantee that it will be completed when this command returns. shutdown Shuts down the Erlang process on which RabbitMQ is running. The command is blocking and will return after the Erlang process exits. If RabbitMQ fails to stop, it will return a non-zero exit code. Unlike the stop command, the shutdown command: · does not require a pid_file to wait for the Erlang process to exit · returns a non-zero exit code if RabbitMQ node is not running For example, to shut down the Erlang process on which RabbitMQ is running: rabbitmqctl shutdown start_app Starts the RabbitMQ application. This command is typically run after performing other management actions that required the RabbitMQ application to be stopped, e.g. reset. For example, to instruct the RabbitMQ node to start the RabbitMQ application: rabbitmqctl start_app stop [pid_file] Stops the Erlang node on which RabbitMQ is running. To restart the node follow the instructions for "Running the Server" in the installation: http://www.rabbitmq.com/download.html guide. If a pid_file is specified, also waits for the process specified there to terminate. See the description of the wait command for details on this file. For example, to instruct the RabbitMQ node to terminate: rabbitmqctl stop stop_app Stops the RabbitMQ application, leaving the Erlang node running. This command is typically run prior to performing other manage‐ ment actions that require the RabbitMQ application to be stopped, e.g. reset. For example, to instruct the RabbitMQ node to stop the RabbitMQ application: rabbitmqctl stop_app wait pid_file, wait --pid pid Waits for the RabbitMQ application to start. This command will wait for the RabbitMQ application to start at the node. It will wait for the pid file to be created if pidfile is specified, then for a process with a pid specified in the pid file or the --pid argument, and then for the RabbitMQ application to start in that process. It will fail if the process terminates without starting the RabbitMQ application. If the specified pidfile is not created or erlang node is not started within --timeout the command will fail. Default timeout is 10 seconds. A suitable pid file is created by the rabbitmq-server(8) script. By default this is located in the Mnesia directory. Modify the RABBITMQ_PID_FILE environment variable to change the location. For example, this command will return when the RabbitMQ node has started up: rabbitmqctl wait /var/run/rabbitmq/pid Cluster Management join_cluster clusternode [--ram] clusternode Node to cluster with. --ram If provided, the node will join the cluster as a RAM node. Instructs the node to become a member of the cluster that the specified node is in. Before clustering, the node is reset, so be careful when using this command. For this command to succeed the RabbitMQ application must have been stopped, e.g. with stop_app. Cluster nodes can be of two types: disc or RAM. Disc nodes replicate data in RAM and on disc, thus providing redundancy in the event of node failure and recovery from global events such as power failure across all nodes. RAM nodes replicate data in RAM only (with the exception of queue contents, which can reside on disc if the queue is persistent or too big to fit in memory) and are mainly used for scalability. RAM nodes are more performant only when managing resources (e.g. adding/removing queues, exchanges, or bindings). A cluster must always have at least one disc node, and usually should have more than one. The node will be a disc node by default. If you wish to create a RAM node, provide the --ram flag. After executing the join_cluster command, whenever the RabbitMQ application is started on the current node it will attempt to connect to the nodes that were in the cluster when the node went down. To leave a cluster, reset the node. You can also remove nodes remotely with the forget_cluster_node command. For more details see the Clustering: http://www.rabbitmq.com/clustering.html guide. For example, this command instructs the RabbitMQ node to join the cluster that "hare@elena" is part of, as a ram node: rabbitmqctl join_cluster hare@elena --ram cluster_status Displays all the nodes in the cluster grouped by node type, together with the currently running nodes. For example, this command displays the nodes in the cluster: rabbitmqctl cluster_status change_cluster_node_type type Changes the type of the cluster node. The type must be one of the following: · disc · ram The node must be stopped for this operation to succeed, and when turning a node into a RAM node the node must not be the only disc node in the cluster. For example, this command will turn a RAM node into a disc node: rabbitmqctl change_cluster_node_type disc forget_cluster_node [--offline] --offline Enables node removal from an offline node. This is only useful in the situation where all the nodes are offline and the last node to go down cannot be brought online, thus preventing the whole cluster from starting. It should not be used in any other circumstances since it can lead to inconsistencies. Removes a cluster node remotely. The node that is being removed must be offline, while the node we are removing from must be online, except when using the --offline flag. When using the --offline flag , rabbitmqctl will not attempt to connect to a node as normal; instead it will temporarily become the node in order to make the change. This is useful if the node cannot be started normally. In this case the node will become the canonical source for cluster metadata (e.g. which queues exist), even if it was not before. Therefore you should use this command on the latest node to shut down if at all possible. For example, this command will remove the node "rabbit@stringer" from the node "hare@mcnulty": rabbitmqctl -n hare@mcnulty forget_cluster_node rabbit@stringer rename_cluster_node oldnode1 newnode1 [oldnode2 newnode2 ...] Supports renaming of cluster nodes in the local database. This subcommand causes rabbitmqctl to temporarily become the node in order to make the change. The local cluster node must there‐ fore be completely stopped; other nodes can be online or offline. This subcommand takes an even number of arguments, in pairs rep‐ resenting the old and new names for nodes. You must specify the old and new names for this node and for any other nodes that are stopped and being renamed at the same time. It is possible to stop all nodes and rename them all simultane‐ ously (in which case old and new names for all nodes must be given to every node) or stop and rename nodes one at a time (in which case each node only needs to be told how its own name is changing). For example, this command will rename the node "rabbit@misshelpful" to the node "rabbit@cordelia" rabbitmqctl rename_cluster_node rabbit@misshelpful rabbit@cordelia update_cluster_nodes clusternode clusternode The node to consult for up-to-date information. Instructs an already clustered node to contact clusternode to cluster when waking up. This is different from join_cluster since it does not join any cluster - it checks that the node is already in a cluster with clusternode. The need for this command is motivated by the fact that clusters can change while a node is offline. Consider the situation in which node A and B are clustered. A goes down, C clusters with B, and then B leaves the cluster. When A wakes up, it'll try to contact B, but this will fail since B is not in the cluster any‐ more. The following command will solve this situation: update_cluster_nodes -n A C force_boot Ensures that the node will start next time, even if it was not the last to shut down. Normally when you shut down a RabbitMQ cluster altogether, the first node you restart should be the last one to go down, since it may have seen things happen that other nodes did not. But sometimes that's not possible: for instance if the entire cluster loses power then all nodes may think they were not the last to shut down. In such a case you can invoke force_boot while the node is down. This will tell the node to unconditionally start next time you ask it to. If any changes happened to the cluster after this node shut down, they will be lost. If the last node to go down is permanently lost then you should use forget_cluster_node --offline in preference to this command, as it will ensure that mirrored queues which were mastered on the lost node get promoted. For example, this will force the node not to wait for other nodes next time it is started: rabbitmqctl force_boot sync_queue [-p vhost] queue queue The name of the queue to synchronise. Instructs a mirrored queue with unsynchronised slaves to synchro‐ nise itself. The queue will block while synchronisation takes place (all publishers to and consumers from the queue will block). The queue must be mirrored for this command to succeed. Note that unsynchronised queues from which messages are being drained will become synchronised eventually. This command is primarily useful for queues which are not being drained. cancel_sync_queue [-p vhost] queue queue The name of the queue to cancel synchronisation for. Instructs a synchronising mirrored queue to stop synchronising itself. purge_queue [-p vhost] queue queue The name of the queue to purge. Purges a queue (removes all messages in it). set_cluster_name name Sets the cluster name to name. The cluster name is announced to clients on connection, and used by the federation and shovel plugins to record where a message has been. The cluster name is by default derived from the hostname of the first node in the cluster, but can be changed. For example, this sets the cluster name to "london": rabbitmqctl set_cluster_name london User Management Note that rabbitmqctl manages the RabbitMQ internal user database. Users from any alternative authentication backend will not be visible to rabbitmqctl. add_user username password username The name of the user to create. password The password the created user will use to log in to the broker. For example, this command instructs the RabbitMQ broker to create a (non-administrative) user named "tonyg" with (initial) password "changeit": rabbitmqctl add_user tonyg changeit delete_user username username The name of the user to delete. For example, this command instructs the RabbitMQ broker to delete the user named "tonyg": rabbitmqctl delete_user tonyg change_password username newpassword username The name of the user whose password is to be changed. newpassword The new password for the user. For example, this command instructs the RabbitMQ broker to change the password for the user named "tonyg" to "newpass": rabbitmqctl change_password tonyg newpass clear_password username username The name of the user whose password is to be cleared. For example, this command instructs the RabbitMQ broker to clear the password for the user named "tonyg": rabbitmqctl clear_password tonyg This user now cannot log in with a password (but may be able to through e.g. SASL EXTERNAL if configured). authenticate_user username password username The name of the user. password The password of the user. For example, this command instructs the RabbitMQ broker to authenticate the user named "tonyg" with password "verifyit": rabbitmqctl authenticate_user tonyg verifyit set_user_tags username [tag ...] username The name of the user whose tags are to be set. tag Zero, one or more tags to set. Any existing tags will be removed. For example, this command instructs the RabbitMQ broker to ensure the user named "tonyg" is an administrator: rabbitmqctl set_user_tags tonyg administrator This has no effect when the user logs in via AMQP, but can be used to permit the user to manage users, virtual hosts and per‐ missions when the user logs in via some other means (for example with the management plugin). This command instructs the RabbitMQ broker to remove any tags from the user named "tonyg": rabbitmqctl set_user_tags tonyg list_users Lists users. Each result row will contain the user name followed by a list of the tags set for that user. For example, this command instructs the RabbitMQ broker to list all users: rabbitmqctl list_users Access Control Note that rabbitmqctl manages the RabbitMQ internal user database. Per‐ missions for users from any alternative authorisation backend will not be visible to rabbitmqctl. add_vhost vhost vhost The name of the virtual host entry to create. Creates a virtual host. For example, this command instructs the RabbitMQ broker to create a new virtual host called "test": rabbitmqctl add_vhost test delete_vhost vhost vhost The name of the virtual host entry to delete. Deletes a virtual host. Deleting a virtual host deletes all its exchanges, queues, bind‐ ings, user permissions, parameters and policies. For example, this command instructs the RabbitMQ broker to delete the virtual host called "test": rabbitmqctl delete_vhost test list_vhosts [vhostinfoitem ...] Lists virtual hosts. The vhostinfoitem parameter is used to indicate which virtual host information items to include in the results. The column order in the results will match the order of the parameters. vhostinfoitem can take any value from the list that follows: name The name of the virtual host with non-ASCII characters escaped as in C. tracing Whether tracing is enabled for this virtual host. If no vhostinfoitem are specified then the vhost name is dis‐ played. For example, this command instructs the RabbitMQ broker to list all virtual hosts: rabbitmqctl list_vhosts name tracing set_permissions [-p vhost] user conf write read vhost The name of the virtual host to which to grant the user access, defaulting to "/". user The name of the user to grant access to the specified virtual host. conf A regular expression matching resource names for which the user is granted configure permissions. write A regular expression matching resource names for which the user is granted write permissions. read A regular expression matching resource names for which the user is granted read permissions. Sets user permissions. For example, this command instructs the RabbitMQ broker to grant the user named "tonyg" access to the virtual host called "/myvhost", with configure permissions on all resources whose names starts with "tonyg-", and write and read permissions on all resources: rabbitmqctl set_permissions -p /myvhost tonyg "^tonyg-.*" ".*" ".*" clear_permissions [-p vhost] username vhost The name of the virtual host to which to deny the user access, defaulting to "/". username The name of the user to deny access to the specified vir‐ tual host. Sets user permissions. For example, this command instructs the RabbitMQ broker to deny the user named "tonyg" access to the virtual host called "/myvhost": rabbitmqctl clear_permissions -p /myvhost tonyg list_permissions [-p vhost] vhost The name of the virtual host for which to list the users that have been granted access to it, and their permis‐ sions. Defaults to "/". Lists permissions in a virtual host. For example, this command instructs the RabbitMQ broker to list all the users which have been granted access to the virtual host called "/myvhost", and the permissions they have for operations on resources in that virtual host. Note that an empty string means no permissions granted: rabbitmqctl list_permissions -p /myvhost list_user_permissions username username The name of the user for which to list the permissions. Lists user permissions. For example, this command instructs the RabbitMQ broker to list all the virtual hosts to which the user named "tonyg" has been granted access, and the permissions the user has for operations on resources in these virtual hosts: rabbitmqctl list_user_permissions tonyg set_topic_permissions [-p vhost] user exchange write read vhost The name of the virtual host to which to grant the user access, defaulting to "/". user The name of the user the permissions apply to in the tar‐ get virtual host. exchange The name of the topic exchange the authorisation check will be applied to. write A regular expression matching the routing key of the pub‐ lished message. read A regular expression matching the routing key of the con‐ sumed message. Sets user topic permissions. For example, this command instructs the RabbitMQ broker to let the user named "tonyg" publish and consume messages going through the "amp.topic" exchange of the "/myvhost" virtual host with a routing key starting with "tonyg-": rabbitmqctl set_topic_permissions -p /myvhost tonyg amq.topic "^tonyg-.*" "^tonyg-.*" Topic permissions support variable expansion for the following variables: username, vhost, and client_id. Note that client_id is expanded only when using MQTT. The previous example could be made more generic by using "^{username}-.*": rabbitmqctl set_topic_permissions -p /myvhost tonyg amq.topic "^{username}-.*" "^{username}-.*" clear_topic_permissions [-p vhost] username [exchange] vhost The name of the virtual host to which to clear the topic permissions, defaulting to "/". username The name of the user to clear topic permissions to the specified virtual host. exchange The name of the topic exchange to clear topic permis‐ sions, defaulting to all the topic exchanges the given user has topic permissions for. Clear user topic permissions. For example, this command instructs the RabbitMQ broker to remove topic permissions for user named "tonyg" for the topic exchange "amq.topic" in the virtual host called "/myvhost": rabbitmqctl clear_topic_permissions -p /myvhost tonyg amq.topic list_topic_permissions [-p vhost] vhost The name of the virtual host for which to list the users topic permissions. Defaults to "/". Lists topic permissions in a virtual host. For example, this command instructs the RabbitMQ broker to list all the users which have been granted topic permissions in the virtual host called "/myvhost:" rabbitmqctl list_topic_permissions -p /myvhost list_user_topic_permissions username username The name of the user for which to list the topic permis‐ sions. Lists user topic permissions. For example, this command instructs the RabbitMQ broker to list all the virtual hosts to which the user named "tonyg" has been granted access, and the topic permissions the user has in these virtual hosts: rabbitmqctl list_topic_user_permissions tonyg Parameter Management Certain features of RabbitMQ (such as the federation plugin) are con‐ trolled by dynamic, cluster-wide parameters. There are 2 kinds of parame‐ ters: parameters scoped to a virtual host and global parameters. Each vhost-scoped parameter consists of a component name, a name and a value. The component name and name are strings, and the value is an Erlang term. A global parameter consists of a name and value. The name is a string and the value is an Erlang term. Parameters can be set, cleared and listed. In general you should refer to the documentation for the feature in question to see how to set parameters. set_parameter [-p vhost] component_name name value Sets a parameter. component_name The name of the component for which the parameter is being set. name The name of the parameter being set. value The value for the parameter, as a JSON term. In most shells you are very likely to need to quote this. For example, this command sets the parameter "local_username" for the "federation" component in the default virtual host to the JSON term "guest": rabbitmqctl set_parameter federation local_username "guest" clear_parameter [-p vhost] component_name key Clears a parameter. component_name The name of the component for which the parameter is being cleared. name The name of the parameter being cleared. For example, this command clears the parameter "local_username" for the "federation" component in the default virtual host: rabbitmqctl clear_parameter federation local_username list_parameters [-p vhost] Lists all parameters for a virtual host. For example, this command lists all parameters in the default virtual host: rabbitmqctl list_parameters set_global_parameter name value Sets a global runtime parameter. This is similar to set_parameter but the key-value pair isn't tied to a virtual host. name The name of the global runtime parameter being set. value The value for the global runtime parameter, as a JSON term. In most shells you are very likely to need to quote this. For example, this command sets the global runtime parameter "mqtt_default_vhosts" to the JSON term {"O=client,CN=guest":"/"}: rabbitmqctl set_global_parameter mqtt_default_vhosts '{"O=client,CN=guest":"/"}' clear_global_parameter name Clears a global runtime parameter. This is similar to clear_parameter but the key-value pair isn't tied to a virtual host. name The name of the global runtime parameter being cleared. For example, this command clears the global runtime parameter "mqtt_default_vhosts": rabbitmqctl clear_global_parameter mqtt_default_vhosts list_global_parameters Lists all global runtime parameters. This is similar to list_parameters but the global runtime parameters are not tied to any virtual host. For example, this command lists all global parameters: rabbitmqctl list_global_parameters Policy Management Policies are used to control and modify the behaviour of queues and exchanges on a cluster-wide basis. Policies apply within a given vhost, and consist of a name, pattern, definition and an optional priority. Policies can be set, cleared and listed. set_policy [-p vhost] [--priority priority] [--apply-to apply-to] name pattern definition Sets a policy. name The name of the policy. pattern The regular expression, which when matches on a given resources causes the policy to apply. definition The definition of the policy, as a JSON term. In most shells you are very likely to need to quote this. priority The priority of the policy as an integer. Higher numbers indicate greater precedence. The default is 0. apply-to Which types of object this policy should apply to. Pos‐ sible values are: · queues · exchanges · all The default is all .. For example, this command sets the policy "federate-me" in the default virtual host so that built-in exchanges are federated: rabbitmqctl set_policy federate-me ^amq. '{"federation-upstream-set":"all"}' clear_policy [-p vhost] name Clears a policy. name The name of the policy being cleared. For example, this command clears the "federate-me" policy in the default virtual host: rabbitmqctl clear_policy federate-me list_policies [-p vhost] Lists all policies for a virtual host. For example, this command lists all policies in the default vir‐ tual host: rabbitmqctl list_policies set_operator_policy [-p vhost] [--priority priority] [--apply-to apply-to] name pattern definition Sets an operator policy that overrides a subset of arguments in user policies. Arguments are identical to those of set_policy. Supported arguments are: · expires · message-ttl · max-length · max-length-bytes clear_operator_policy [-p vhost] name Clears an operator policy. Arguments are identical to those of clear_policy. list_operator_policies [-p vhost] Lists operator policy overrides for a virtual host. Arguments are identical to those of list_policies. Virtual Host Limits It is possible to enforce certain limits on virtual hosts. set_vhost_limits [-p vhost] definition Sets virtual host limits. definition The definition of the limits, as a JSON term. In most shells you are very likely to need to quote this. Recognised limits are: · max-connections · max-queues Use a negative value to specify "no limit". For example, this command limits the max number of concurrent connections in vhost "qa_env" to 64: rabbitmqctl set_vhost_limits -p qa_env '{"max-connections": 64}' This command limits the max number of queues in vhost "qa_env" to 256: rabbitmqctl set_vhost_limits -p qa_env '{"max-queues": 256}' This command clears the max number of connections limit in vhost "qa_env": rabbitmqctl set_vhost_limits -p qa_env '{"max-connections": -1}' This command disables client connections in vhost "qa_env": rabbitmqctl set_vhost_limits -p qa_env '{"max-connections": 0}' clear_vhost_limits [-p vhost] Clears virtual host limits. For example, this command clears vhost limits in vhost "qa_env": rabbitmqctl clear_vhost_limits -p qa_env list_vhost_limits [-p vhost] [--global] Displays configured virtual host limits. --global Show limits for all vhosts. Suppresses the -p parameter. Server Status The server status queries interrogate the server and return a list of results with tab-delimited columns. Some queries ( list_queues, list_exchanges, list_bindings and list_consumers) accept an optional vhost parameter. This parameter, if present, must be specified immedi‐ ately after the query. The list_queues, list_exchanges and list_bindings commands accept an optional virtual host parameter for which to display results. The default value is "/". list_queues [-p vhost] [--offline | --online | --local] [queueinfoitem ...] Returns queue details. Queue details of the "/" virtual host are returned if the -p flag is absent. The -p flag can be used to override this default. Displayed queues can be filtered by their status or location using one of the following mutually exclusive options: --offline List only those durable queues that are not currently available (more specifically, their master node isn't). --online List queues that are currently available (their master node is). --local List only those queues whose master process is located on the current node. The queueinfoitem parameter is used to indicate which queue information items to include in the results. The column order in the results will match the order of the parameters. queueinfoitem can take any value from the list that follows: name The name of the queue with non-ASCII characters escaped as in C. durable Whether or not the queue survives server restarts. auto_delete Whether the queue will be deleted automatically when no longer used. arguments Queue arguments. policy Policy name applying to the queue. pid Id of the Erlang process associated with the queue. owner_pid Id of the Erlang process representing the connection which is the exclusive owner of the queue. Empty if the queue is non-exclusive. exclusive True if queue is exclusive (i.e. has owner_pid), false otherwise. exclusive_consumer_pid Id of the Erlang process representing the channel of the exclusive consumer subscribed to this queue. Empty if there is no exclusive consumer. exclusive_consumer_tag Consumer tag of the exclusive consumer subscribed to this queue. Empty if there is no exclusive consumer. messages_ready Number of messages ready to be delivered to clients. messages_unacknowledged Number of messages delivered to clients but not yet acknowledged. messages Sum of ready and unacknowledged messages (queue depth). messages_ready_ram Number of messages from messages_ready which are resident in ram. messages_unacknowledged_ram Number of messages from messages_unacknowledged which are resident in ram. messages_ram Total number of messages which are resident in ram. messages_persistent Total number of persistent messages in the queue (will always be 0 for transient queues). message_bytes Sum of the size of all message bodies in the queue. This does not include the message properties (including head‐ ers) or any overhead. message_bytes_ready Like message_bytes but counting only those messages ready to be delivered to clients. message_bytes_unacknowledged Like message_bytes but counting only those messages delivered to clients but not yet acknowledged. message_bytes_ram Like message_bytes but counting only those messages which are in RAM. message_bytes_persistent Like message_bytes but counting only those messages which are persistent. head_message_timestamp The timestamp property of the first message in the queue, if present. Timestamps of messages only appear when they are in the paged-in state. disk_reads Total number of times messages have been read from disk by this queue since it started. disk_writes Total number of times messages have been written to disk by this queue since it started. consumers Number of consumers. consumer_utilisation Fraction of the time (between 0.0 and 1.0) that the queue is able to immediately deliver messages to consumers. This can be less than 1.0 if consumers are limited by network congestion or prefetch count. memory Bytes of memory consumed by the Erlang process associated with the queue, including stack, heap and internal struc‐ tures. slave_pids If the queue is mirrored, this gives the IDs of the cur‐ rent slaves. synchronised_slave_pids If the queue is mirrored, this gives the IDs of the cur‐ rent slaves which are synchronised with the master - i.e. those which could take over from the master without mes‐ sage loss. state The state of the queue. Normally "running", but may be "{syncing, message_count}" if the queue is synchronising. Queues which are located on cluster nodes that are cur‐ rently down will be shown with a status of "down" (and most other queueinfoitem will be unavailable). If no queueinfoitem are specified then queue name and depth are displayed. For example, this command displays the depth and number of con‐ sumers for each queue of the virtual host named "/myvhost" rabbitmqctl list_queues -p /myvhost messages consumers list_exchanges [-p vhost] [exchangeinfoitem ...] Returns exchange details. Exchange details of the "/" virtual host are returned if the -p flag is absent. The -p flag can be used to override this default. The exchangeinfoitem parameter is used to indicate which exchange information items to include in the results. The column order in the results will match the order of the parameters. exchangeinfoitem can take any value from the list that follows: name The name of the exchange with non-ASCII characters escaped as in C. type The exchange type, such as: · direct · topic · headers · fanout durable Whether or not the exchange survives server restarts. auto_delete Whether the exchange will be deleted automatically when no longer used. internal Whether the exchange is internal, i.e. cannot be directly published to by a client. arguments Exchange arguments. policy Policy name for applying to the exchange. If no exchangeinfoitem are specified then exchange name and type are displayed. For example, this command displays the name and type for each exchange of the virtual host named "/myvhost": rabbitmqctl list_exchanges -p /myvhost name type list_bindings [-p vhost] [bindinginfoitem ...] Returns binding details. By default the bindings for the "/" virtual host are returned. The -p flag can be used to override this default. The bindinginfoitem parameter is used to indicate which binding information items to include in the results. The column order in the results will match the order of the parameters. bindinginfoitem can take any value from the list that follows: source_name The name of the source of messages to which the binding is attached. With non-ASCII characters escaped as in C. source_kind The kind of the source of messages to which the binding is attached. Currently always exchange. With non-ASCII characters escaped as in C. destination_name The name of the destination of messages to which the binding is attached. With non-ASCII characters escaped as in C. destination_kind The kind of the destination of messages to which the binding is attached. With non-ASCII characters escaped as in C. routing_key The binding's routing key, with non-ASCII characters escaped as in C. arguments The binding's arguments. If no bindinginfoitem are specified then all above items are dis‐ played. For example, this command displays the exchange name and queue name of the bindings in the virtual host named "/myvhost" rabbitmqctl list_bindings -p /myvhost exchange_name queue_name list_connections [connectioninfoitem ...] Returns TCP/IP connection statistics. The connectioninfoitem parameter is used to indicate which con‐ nection information items to include in the results. The column order in the results will match the order of the parameters. connectioninfoitem can take any value from the list that follows: pid Id of the Erlang process associated with the connection. name Readable name for the connection. port Server port. host Server hostname obtained via reverse DNS, or its IP address if reverse DNS failed or was disabled. peer_port Peer port. peer_host Peer hostname obtained via reverse DNS, or its IP address if reverse DNS failed or was not enabled. ssl Boolean indicating whether the connection is secured with SSL. ssl_protocol SSL protocol (e.g. "tlsv1"). ssl_key_exchange SSL key exchange algorithm (e.g. "rsa"). ssl_cipher SSL cipher algorithm (e.g. "aes_256_cbc"). ssl_hash SSL hash function (e.g. "sha"). peer_cert_subject The subject of the peer's SSL certificate, in RFC4514 form. peer_cert_issuer The issuer of the peer's SSL certificate, in RFC4514 form. peer_cert_validity The period for which the peer's SSL certificate is valid. state Connection state; one of: · starting · tuning · opening · running · flow · blocking · blocked · closing · closed channels Number of channels using the connection. protocol Version of the AMQP protocol in use; currently one of: · {0,9,1} · {0,8,0} Note that if a client requests an AMQP 0-9 connection, we treat it as AMQP 0-9-1. auth_mechanism SASL authentication mechanism used, such as "PLAIN". user Username associated with the connection. vhost Virtual host name with non-ASCII characters escaped as in C. timeout Connection timeout / negotiated heartbeat interval, in seconds. frame_max Maximum frame size (bytes). channel_max Maximum number of channels on this connection. client_properties Informational properties transmitted by the client during connection establishment. recv_oct Octets received. recv_cnt Packets received. send_oct Octets send. send_cnt Packets sent. send_pend Send queue size. connected_at Date and time this connection was established, as time‐ stamp. If no connectioninfoitem are specified then user, peer host, peer port, time since flow control and memory block state are dis‐ played. For example, this command displays the send queue size and server port for each connection: rabbitmqctl list_connections send_pend port list_channels [channelinfoitem ...] Returns information on all current channels, the logical contain‐ ers executing most AMQP commands. This includes channels that are part of ordinary AMQP connections, and channels created by various plug-ins and other extensions. The channelinfoitem parameter is used to indicate which channel information items to include in the results. The column order in the results will match the order of the parameters. channelinfoitem can take any value from the list that follows: pid Id of the Erlang process associated with the connection. connection Id of the Erlang process associated with the connection to which the channel belongs. name Readable name for the channel. number The number of the channel, which uniquely identifies it within a connection. user Username associated with the channel. vhost Virtual host in which the channel operates. transactional True if the channel is in transactional mode, false oth‐ erwise. confirm True if the channel is in confirm mode, false otherwise. consumer_count Number of logical AMQP consumers retrieving messages via the channel. messages_unacknowledged Number of messages delivered via this channel but not yet acknowledged. messages_uncommitted Number of messages received in an as yet uncommitted transaction. acks_uncommitted Number of acknowledgements received in an as yet uncom‐ mitted transaction. messages_unconfirmed Number of published messages not yet confirmed. On chan‐ nels not in confirm mode, this remains 0. prefetch_count QoS prefetch limit for new consumers, 0 if unlimited. global_prefetch_count QoS prefetch limit for the entire channel, 0 if unlim‐ ited. If no channelinfoitem are specified then pid, user, con‐ sumer_count, and messages_unacknowledged are assumed. For example, this command displays the connection process and count of unacknowledged messages for each channel: rabbitmqctl list_channels connection messages_unacknowledged list_consumers [-p vhost] Lists consumers, i.e. subscriptions to a queue´s message stream. Each line printed shows, separated by tab characters, the name of the queue subscribed to, the id of the channel process via which the subscription was created and is managed, the consumer tag which uniquely identifies the subscription within a channel, a boolean indicating whether acknowledgements are expected for mes‐ sages delivered to this consumer, an integer indicating the prefetch limit (with 0 meaning "none"), and any arguments for this consumer. status Displays broker status information such as the running applica‐ tions on the current Erlang node, RabbitMQ and Erlang versions, OS name, memory and file descriptor statistics. (See the cluster_status command to find out which nodes are clustered and running.) For example, this command displays information about the RabbitMQ broker: rabbitmqctl status node_health_check Health check of the RabbitMQ node. Verifies the rabbit applica‐ tion is running, list_queues and list_channels return, and alarms are not set. For example, this command performs a health check on the RabbitMQ node: rabbitmqctl node_health_check -n rabbit@stringer environment Displays the name and value of each variable in the application environment for each running application. report Generate a server status report containing a concatenation of all server status information for support purposes. The output should be redirected to a file when accompanying a support request. For example, this command creates a server report which may be attached to a support request email: rabbitmqctl report > server_report.txt eval expr Evaluate an arbitrary Erlang expression. For example, this command returns the name of the node to which rabbitmqctl has connected: rabbitmqctl eval "node()." Miscellaneous close_connection connectionpid explanation connectionpid Id of the Erlang process associated with the connection to close. explanation Explanation string. Instructs the broker to close the connection associated with the Erlang process id connectionpid (see also the list_connections command), passing the explanation string to the connected client as part of the AMQP connection shutdown protocol. For example, this command instructs the RabbitMQ broker to close the connection associated with the Erlang process id "<[email protected]>", passing the explanation "go away" to the connected client: rabbitmqctl close_connection "<[email protected]>" "go away" close_all_connections [-p vhost] [--global] [--per-connection-delay delay] [--limit limit] explanation -p vhost The name of the virtual host for which connections should be closed. Ignored when --global is specified. --global If connections should be close for all vhosts. Overrides -p --per-connection-delay delay Time in milliseconds to wait after each connection clos‐ ing. --limit limit Number of connection to close. Only works per vhost. Ignored when --global is specified. explanation Explanation string. Instructs the broker to close all connections for the specified vhost or entire RabbitMQ node. For example, this command instructs the RabbitMQ broker to close 10 connections on "qa_env" vhost, passing the explanation "Please close": rabbitmqctl close_all_connections -p qa_env --limit 10 'Please close' This command instructs broker to close all connections to the node: rabbitmqctl close_all_connections --global trace_on [-p vhost] vhost The name of the virtual host for which to start tracing. Starts tracing. Note that the trace state is not persistent; it will revert to being off if the server is restarted. trace_off [-p vhost] vhost The name of the virtual host for which to stop tracing. Stops tracing. set_vm_memory_high_watermark fraction fraction The new memory threshold fraction at which flow control is triggered, as a floating point number greater than or equal to 0. set_vm_memory_high_watermark absolute memory_limit memory_limit The new memory limit at which flow control is triggered, expressed in bytes as an integer number greater than or equal to 0 or as a string with memory units (e.g. 512M or 1G). Available units are: k, kiB kibibytes (2^10 bytes) M, MiB mebibytes (2^20 bytes) G, GiB gibibytes (2^30 bytes) kB kilobytes (10^3 bytes) MB megabytes (10^6 bytes) GB gigabytes (10^9 bytes) set_disk_free_limit disk_limit disk_limit Lower bound limit as an integer in bytes or a string with memory units (see vm_memory_high_watermark), e.g. 512M or 1G. Once free disk space reaches the limit, a disk alarm will be set. set_disk_free_limit mem_relative fraction fraction Limit relative to the total amount available RAM as a non-negative floating point number. Values lower than 1.0 can be dangerous and should be used carefully. encode value passphrase [--cipher cipher] [--hash hash] [--iterations iterations] value passphrase Value to encrypt and passphrase. For example: rabbitmqctl encode '<<"guest">>' mypassphrase --cipher cipher --hash hash --iterations iterations Options to specify the encryption settings. They can be used independently. For example: rabbitmqctl encode --cipher blowfish_cfb64 --hash sha256 --iterations 10000 '<<"guest">>' mypassphrase decode value passphrase [--cipher cipher] [--hash hash] [--iterations iterations] value passphrase Value to decrypt (as produced by the encode command) and passphrase. For example: rabbitmqctl decode '{encrypted, <<"...">>}' mypassphrase --cipher cipher --hash hash --iterations iterations Options to specify the decryption settings. They can be used independently. For example: rabbitmqctl decode --cipher blowfish_cfb64 --hash sha256 --iterations 10000 '{encrypted,<<"...">>} mypassphrase list_hashes Lists hash functions supported by encoding commands. For example, this command instructs the RabbitMQ broker to list all hash functions supported by encoding commands: rabbitmqctl list_hashes list_ciphers Lists cipher suites supported by encoding commands. For example, this command instructs the RabbitMQ broker to list all cipher suites supported by encoding commands: rabbitmqctl list_ciphers PLUGIN COMMANDS RabbitMQ plugins can extend rabbitmqctl tool to add new commands when enabled.
