[smokeping-users] Relation between step, pings and graphs

[Peter Kristolaitis]

Hi Michal;

Step = how many seconds each round of polling lasts
Pings = how many pings are sent to each target during each step

In terms of relation to RRD,
1 step = 1 data point in the RRD file

Note that you should set the values such that you can ping each target 
on your network 'pings' times within 'step' seconds, otherwise you will 
end up with blank data points in your graph.

For my production setup, I use step = 180, pings = 20.  In practice this 
means that each data point in the RRD file/graph represents a 3-minute 
timespan with aggregate data from 20 ping results.

HTH,
- Pete
