Hi,

you have to reconfigure whole database definition

*** Database ***
# every 30 seconds send 10 pings (it is quite lot IMHO)
step     = 30
pings    = 10

# consfn mrhb steps total

AVERAGE  0.5    1  2880 # 24 hours of full data
AVERAGE  0.5   60   1344 # 28 days of 1half hour averages
    MIN  0.5   60 1344
    MAX  0.5   60 1344
AVERAGE  0.5  720  1600 # 400 days of 6hour averages
    MAX  0.5  720  1600
    MIN  0.5  720  1600

The RRD files will be quite big so the polling machine will have quite big IO 
wait.

You can do that without any technological mumbo-jumbo...
