Thanks guys,

Ya I rebooted and figured out that my question was flawed (brain
reboot, not system). I'm running a query on a DB and getting a
response with say, how many rows , I than run that same query an hour
later and would like to know how much it's changed.

Using DERIVE and COUNTERS my numbers in the graphs are like 6 1 2 when
the actual results of the query were;

Retrieved data for rows (): 281392,20695,88650

And the numbers previous were

 Retrieved data for rows (): 281016,20654,88501

So I'm unclear where cricket/rrd is grabbing the results of 6,1,2 ( as
seen in the graph), when the differential is quite a bit more.

I thought maybe it was in my scaling or use of integer in precision,
but that doesn't seem like the case. In all honesty would be nice to
follow this with getting the difference from the day previous at the
same check time. But right now something is not right, not using
scaling, not using units, but something is giving me the wrong results

Thanks again

Tory
