9.12. QMF Client Connection Events
Whenever a client connects to or disconnects from the broker, a QMF Event message is generated and sent to a QMF topic.
The QMF topics for these events are:
| QMF queue | Purpose |
|---|---|
|
qmf.default.topic/agent.ind.event.org_apache_qpid_broker.clientConnect.#
|
Client connections
|
|
qmf.default.topic/agent.ind.event.org_apache_qpid_broker.clientConnectFail.#
|
Failed connection attempts
|
|
qmf.default.topic/agent.ind.event.org_apache_qpid_broker.clientDisconnect.#
|
Client disconnections
|
Additional properties in the QMF Client Connection and Disconnection event messages match connections and disconnections to specific clients to enable auditing and troubleshooting:
client_ppid[1]client_pidclient_process
Here is an example of a QMF client connection event message, demonstrating the client connection information:
