> 1) why are you updating 5 DS, when you haved defined only 4
I'm not using 5 DS - the first column is time (unix time in seconds)

> 2) why are you using absolute values? If you update from counters, you
should use GAUGE? 
what do you mean "why I'm using absolute values?"

with GAUGE it's absolutely wrong 
look at there image what shows with "GAUGE"
