[rabbitmq-discuss] Clarification needed for HA of RabbitMQ statistics database

Fri Jan 13 11:55:05 GMT 2012

That information is actually out of date (theoretically as of 2.6.0 
although in practice the stats DB recovery was buggy until 2.7.1). I'll 
update it.

So now the stats DB will get recreated on another node in the cluster 
(assuming there is another node which is running the full mgmt plugin, 
not just the agent). When the DB is recreated it will gather the 
information it needs from the rest of the cluster. So there shouldn't be 
anything to worry about.

Cheers, Simon
