Hi Olivier V Broker-J did expose a resetStatistics method at the Broker and VirtualHost level, but this for historical reasons, these only ever reset a subset of statistics exposed by the Broker. The newer cumulative statistics were never included - which was always a bug.
The problem was that in order to reset all counters to zero atomically, you would need to lock. This wasn't acceptable from a performance perspective for what is an orthogonal concern. Without locking, you'd always risk your accounting being out. One of the use-cases for the statistics is demonstrating that the Broker has not lost a message, something that could not be achieved if the tallies weren't consistent. The methods were removed by QPID-7799. Keith.
