[jira] [Updated] (QPID-3869) Connection Logger tool (QMF1/python)
connection-logger is used to provide detailed information about connections
made to a broker.
[ https://issues.apache.org/jira/browse/QPID-3869?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Fraser Adams updated QPID-3869:
-------------------------------
Attachment: connection-logger
Updated with more or less a complete rewrite of the algorith.
The original version is functionally fine but it uses linear searches to dereference QMF Object References (pretty similar to qpid-config really). This is OK and quite readable, but for large numbers of Connections/Queues the performance gets totally trashed.
The latest version dereferences the QMF objects into Maps keyed by ObjectId it also resolves the 0..* associations between Connection and Session and Session and Subscription in order to work out which connections are likely to be producer only Connections.

> connection-logger is used to provide information about connections made to a broker.
> Using qpid-stat for connections is OK but it doesn't provide information as to whether a connection relates to a producer or consumer as this information can only really be derived from the associations between connection, session and binding.
> The Connection Logger tool creates the associations and displays information based on this additional knowledge.
> In default mode connection-logger lists the connections made to a broker along with information about sessions such as whether any subscriptions are associated with the session (if a session has no subscriptions then it's quite likely to be a "producer only" session, so this knowledge is quite useful).
> In "log queue and binding" mode the information provided is very similar to qpid-config -b queues but with additional connection related information provided as with default mode.
