[rrd-users] not being able to get exactly updates made

[Steve Shipway]

You may not want interpolation, but you’re getting it.  All RRD data are normalised to fit in with the interval steps, and you cannot switch this off because of the way the RRD is structured.

 

If you want to avoid this, then ensure your data are submitted with a timestamp exactly on the interval boundary – IE, if your interval is 600s, then (timestamp mod 600) should be zero if you want to make normalisation a null operation.
