The creation of the database is for storing purposes, however if you don't put data in it...it's useless. I assume you are gathering ping roundtrip values and want them to be nicely shown in a graph, right? Any method you have for getting these values is fine, as long as you can put them in the .RRD. For instance here I get the value to update my db: rrdtool update PING.rrd N:`ping -c1 192.168.0.1 | cut -d/ -f4` Epoch refers to the number of secs since January 1, 1970. To update you can explicitily indicate the time or can let rrdtool to get it when updating the values: the 'N' in this example means 'Now'. Easy isn't it? You can store the output and then update, or do it on the fly, as above. Hope it helps.
