The new --mgmt-publish option for the broker defaults to "yes" which leads to the same behavior the broker had before. If this switch is set to "no", the internal management agent will not send updates to the topic exchanges (qpid.management for qmfv1 and qmf.default.topic for qmfv2). This reduces the management overhead in the broker, particularly in cases where there are many components in the broker's wiring (exchanges, queues, bindings, etc.).
When this option is turned off, purely passive tools like qpid-tool and qpid-queue-stats will not work. Active tools like qpid-config and qpid-stat will work normally. Also, management heartbeats and events (qpid-print-events) will work normally regardless of the setting of this option.
