Ted Ross commented on QPID-3785:
--------------------------------
The broker name "amqp-broker" needs to be a constant and needs to be the same
on all brokers. It is basically a well-known way to address the singleton
broker object for management. It is not intended to be an identifying name.
>From a larger QMFv2 perspective, the identifier of an object has two
>components, the component name ("amqp-broker" in this case) and the agent
>name, which is unique for every broker (or non-broker agent). You should
>address your uniqueness issue by using the agent-name component of the object
>address.
This can be illustrated using qmf-tool. After typing "query broker", typing
"list" shows the list of objects that came back from the query:
qmf: list
Accumulated Query Results:
Number Agent Data Address

> In order to allow management tools (e.g. cumin, sesame) to properly work in a
> multibroker environment without overlapping data between different brokers,
> it would be useful to set the broker name through the use of a parameter. For
> example, sesame generate the data identifier starting from the broker name.
> In actual implementation the broker name is always settled to "amqp-broker".
