QMF, the Qpid Management Framework, is an abstraction built on Qpid
messaging to allow object and service oriented remote management. It
consists of three things:
1) A set of APIs for various languages,
2) A protocol that defines message exchange patterns and
message-body formats, and
3) A service, embedded in the C++ broker, that is required to enable
the operation of QMF.
There is an effort in progress to improve the architecture of QMF by
making the following changes and improvements:
1) Remove the requirement for broker-resident functionality,
2) Change QMF message-bodies from a packed binary format to an
amqp-map format,
3) Support operation over federated networks of brokers,
4) Make the identification of agents and objects more flexible, and
5) Improve the scalability and security of QMF.
By removing the requirement for broker-resident services, we simplify
the operation, improve scalability, and allow QMF to run over any AMQP
messaging broker.
Moving from a packed binary data format to a map-based format improves
the flexibility of the protocol. Map-based formats are easy to extend
and evolve without breaking backward compatibility.
Support for federation allows a managed agent or a managing console to
gain access to an entire multi-broker network with a single broker
connection.
There is a new project page devoted to this effort on the Qpid Wiki
(http://qpid.apache.org/qmfv2-project-page.html). Please feel free to
review, comment, and contribute.
