[rrd-users] Re: problem with storing values in the database

[SWATTON, JEANINE]

I have a script where I am having it create a graph every second.  Why
is it that it is not giving me the most current value?

- You need to do consecutive updates before you see any of the updated
data.
- The interval between the updates must be smaller than the heartbeat of

  your DS's
- To store actual values, you must update on an epoch timestamp that is
N times
  your step size, otherwise it will be interpolated.
