------------------------------------
Assignee: Martin Ritchie
> [Java Broker] Improve INFO and above broker log messages to make them more
> useful in a production environment
> -------------------------------------------------------------------------------------------------------------
>
> Key: QPID-1907
> URL: https://issues.apache.org/jira/browse/QPID-1907
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Affects Versions: 0.5
> Reporter: Rob Godfrey
> Assignee: Martin Ritchie
> Fix For: 0.6
>
>
> Log messages at INFO level and above are expected to be turned on in a
> production environment.
> These log messages should thus be aimed at helping to provide users and/or
> support staff with information on the health of the broker; and - in the case
> where there has been some issue - help them diagnose the cause of that issue.
> As such these messages should be readable without knowledge of the Qpid code
> base, they should not be so frequenet as to impact the performance of the
> broker but should be frequent enough such that diagnosis of issues is possible
> Log messages should occur whenever a significant event occurs, for instance
> the creation or destruction of a connection to the broker.
> The log message should contain enough information to be able to correlate the
> message with a business process event. In the case of a connection open the
> remote address, the login name, the virtual host, and the application id
> should be included in the log message.
> In order that the connection can be referred to in other log messages, a
> short unambiguous - but easily recognisable - name should be given for the
> connection (e.g. "con-username-1", where username is replaced by the actual
> user name)
> Suggest the following creation / destruction events are logged:
> Virtual Host
> Connection
> Queue
> Exchange
> Binding (between queue and exchange)
> Subscription to Queue
> In addition to creation/destruction events being logged, we should
> periodically log statistics, e.g. for a queue you might want to record
> Current Queue size (message count)
> Current Queue size (bytes)
> Unacknowledged size (count / bytes)
> Incoming message rate (count / bytes)
> Outgoing message rate (count / bytes)
> Min / Max / Average message size
> Where the last three are measured over the time period between the log
> messages.
> Similar rate statistics could be emitted per connection, exchange,
> subscription, virtualhost etc.
> The logging should be configurable so that it can be turned off by default,
> on for all objects, or on for only certain named queues/exchanges/etc...
