.. zeek:id:: Management::Controller::auto_assign_broker_ports

   :Type: :zeek:type:`bool`

   :Type: :zeek:type:`port`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``2200/tcp``

   The TCP start port to use for auto-assigning cluster node listening
   ports, if :zeek:see:`Management::Controller::auto_assign_broker_ports` is
   enabled (the default) and nodes don't come with those ports assigned.

.. zeek:id:: Management::Controller::auto_assign_metrics_ports
   :source-code: policy/frameworks/management/controller/config.zeek 79 79

   :Type: :zeek:type:`bool`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``T``

   Whether the controller should auto-assign metrics ports for Prometheus
   to nodes that need them and don't have them explicitly specified in
   their cluster configurations.

.. zeek:id:: Management::Controller::auto_assign_metrics_start_port
   :source-code: policy/frameworks/management/controller/config.zeek 84 84

   :Type: :zeek:type:`port`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``9000/tcp``

   The TCP start port to use for auto-assigning metrics exposition ports
   for Prometheus, if :zeek:see:`Management::Controller::auto_assign_metrics_ports`
   is enabled (the default).

.. zeek:id:: Management::Controller::auto_assign_ports
   :source-code: policy/frameworks/management/controller/config.zeek 68 68

   :Type: :zeek:type:`bool`
   :Attributes: :zeek:attr:`&redef` :zeek:attr:`&deprecated` = *"Remove in v7.1: replaced by auto_assign_broker_ports."*
   :Default: ``T``

   :Type: :zeek:type:`port`
   :Attributes: :zeek:attr:`&redef` :zeek:attr:`&deprecated` = *"Remove in v7.1: replaced by auto_assign_broker_start_port."*
   :Default: ``2200/tcp``


.. zeek:id:: Management::Controller::default_port
   :source-code: policy/frameworks/management/controller/config.zeek 44 44

   :Type: :zeek:type:`port`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``2150/tcp``

   The fallback listen port if :zeek:see:`Management::Controller::listen_port`
   remains empty. When set to 0/unknown, the controller won't listen
   for Broker connections. Don't do this if your management agents
   connect to the controller (instead of the default other way around),
   as they require Broker connectivity.

.. zeek:id:: Management::Controller::default_port_websocket
   :source-code: policy/frameworks/management/controller/config.zeek 62 62

   :Type: :zeek:type:`port`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``2149/tcp``

   The fallback listen port if :zeek:see:`Management::Controller::listen_port_websocket`
   remains empty. When set to 0/unknown, the controller won't listen
   for websocket clients.

.. zeek:id:: Management::Controller::directory
   :source-code: policy/frameworks/management/controller/config.zeek 93 93

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``""``

   An optional custom output directory for stdout/stderr. Agent and
   controller currently only log locally, not via the Zeek cluster's
   logger node. This means that if both write to the same log file,
   output gets garbled.

.. zeek:id:: Management::Controller::listen_address
   :source-code: policy/frameworks/management/controller/config.zeek 31 31

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``""``

   The network address the controller listens on for Broker clients. By
   default this uses the ZEEK_CONTROLLER_ADDR environment variable, but
   you may also redef to a specific value. When empty, the
   implementation falls back to :zeek:see:`Management::default_address`.

.. zeek:id:: Management::Controller::listen_address_websocket
   :source-code: policy/frameworks/management/controller/config.zeek 51 51

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``""``

   The network address the controller listens on for websocket
   clients. By default this uses the ZEEK_CONTROLLER_WEBSOCKET_ADDR
   environment variable, but you may also redef to a specific
   value. When empty, the implementation falls back to
   :zeek:see:`Management::default_address`.

.. zeek:id:: Management::Controller::listen_port
   :source-code: policy/frameworks/management/controller/config.zeek 37 37

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``""``

   The network port the controller listens on for Broker clients.
   Defaults to the ZEEK_CONTROLLER_PORT environment variable.
   When that is not set, the implementation falls back to
   :zeek:see:`Management::Controller::default_port`.

.. zeek:id:: Management::Controller::listen_port_websocket
   :source-code: policy/frameworks/management/controller/config.zeek 57 57

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``""``

   The network port the controller listens on for websocket clients.
   Defaults to the ZEEK_CONTROLLER_WEBSOCKET_PORT environment
   variable. When that is not set, the implementation falls back to
   :zeek:see:`Management::Controller::default_port_websocket`.

.. zeek:id:: Management::Controller::name
   :source-code: policy/frameworks/management/controller/config.zeek 12 12

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``""``

   The name of this controller. Defaults to the value of the
   ZEEK_CONTROLLER_NAME environment variable. When that is unset and the
   user doesn't redef the value, the implementation defaults to
   "controller-<hostname>".

.. zeek:id:: Management::Controller::stderr_file
   :source-code: policy/frameworks/management/controller/config.zeek 25 25

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``"stderr"``

   The controller's stderr log name. Like :zeek:see:`Management::Controller::stdout_file`,
   but for the stderr stream.

.. zeek:id:: Management::Controller::stdout_file
   :source-code: policy/frameworks/management/controller/config.zeek 21 21

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``"stdout"``

   The controller's stdout log name. If the string is non-empty, Zeek
   will produce a free-form log (i.e., not one governed by Zeek's
   logging framework) in the controller's working directory. If left
   empty, no such log results.
   
   Note that the controller also establishes a "proper" Zeek log via the
   :zeek:see:`Management::Log` module.

.. zeek:id:: Management::Controller::topic
   :source-code: policy/frameworks/management/controller/config.zeek 87 87

   :Type: :zeek:type:`string`
   :Attributes: :zeek:attr:`&redef`
   :Default: ``"zeek/management/controller"``

   The controller's Broker topic. Clients send requests to this topic.

   state to disk.
