""" Usage: python usage_seed.py [period_length] [sql_connection] python usage_seed.py hour mysql://user:password@nova-db.example.com/nova?charset=utf8 The idea behind usage seeding is to take the current state of all active instances on active compute hosts and insert that data into Stacktach's usage tables. This script should be run against the nova database in each cell which has active compute nodes. The reason for that is because the global cell does not have information on active compute hosts.
