Hi I've set cloudkitty's hashmap for compute -> flavor as below

# cloudkitty hashmap-mapping-create -f $myfield -v m1.tiny -t flat -c 150 -g $mygroup
# cloudkitty hashmap-mapping-create -f $myfield -v m1.small -t flat -c 300 -g $mygroup
# cloudkitty hashmap-mapping-create -f $myfield -v m1.medium -t flat -c 600 -g $mygroup
# cloudkitty hashmap-mapping-create -f $myfield -v m1.large -t flat -c 1200 -g $mygroup
# cloudkitty hashmap-mapping-create -f $myfield -v m1.xlarge -t flat -c 2400 -g $mygroup

and then I create an instance of flavor m1.small which price is 300 I want to know the 300 is for one month or one day or what time period? After 1 hour of the instance created, current report is still 0, so I'd like to make sure about what does 300 mean? Thanks.
