Well, it maintains the overview data for one day by default. That might 
be enough, or it can be extended: 
http://www.rabbitmq.com/management.html#sample-retention

Zheng, to get historical samples, use msg_rates_age, msg_rates_incr, 
data_rates_age, data_rates_incr, lengths_age and lengths_incr query 
string parameters as documented in the last paragraph of the 
introduction here:
