[smokeping-users] Smokeping 2.4.2 - No Graph Data

[Ryan Harden]

I finally gave up working on it and went to sleep. I woke up this
morning and to my surprise I had graph data.

After the master and slaves had been running and updating RRDs for
nearly 10 hours, it finally started drawing data on the graphs.

I can't really explain except maybe by the fact that I change up my RRD
database to account for the 20 pings every 30 seconds.

*** Database ***

step     = 30
pings    = 20

AVERAGE 0.5   1  20160 #7-day worth 30-second avg
AVERAGE 0.5   10  8640  #30-day worth 5-minute avg
AVERAGE 0.5   30 38400 #400-day worth 15-minute avg
MIN 0.5 10 8640
MAX 0.5 10 8640
MIN 0.5 30 38400
MAX 0.5 30 38400

I'm not sure if by changing that it takes longer for smokeping to
calculate or something before it has enough data to draw on the graphs.
