When using the new custom time resolution range (Smokeping 2.x rc), with 
5x EchoPing every 60secs, I can view the complete 60 bars result over 
the 1-hour period (see 1-hour-today.png, but when I zoom into the same 
hour but 24hrs earlier (see 1-hour-yesterday.png) I've lost high def 
results, and instead I'm seeing the 10min average (5 bars for the entire 

I understand that this is a result of default smokeping RRD creation 
specs and an expected way how RRD stores and averages data. In my 
etc/config.dist, the RRD related parameters are as follows:

*** Database ***

step     = 60 <-- every minute
pings    = 5

# consfn mrhb steps total

AVERAGE  0.5   1  1008
AVERAGE  0.5  12  4320
    MIN  0.5  12  4320
    MAX  0.5  12  4320
AVERAGE  0.5 144   720
    MAX  0.5 144   720
    MIN  0.5 144   720

How do I specify the config parameters so that I won't lose the time 
resolution when I zoom back the time-scale. I intend to keep the history 
for 400days. I'm completely aware that the effect of this could end me 
with a huge RRD file :)
