[rrd-users] Incorrect MAX total from consolidated cacti graph

Thu Oct 29 14:52:08 CET 2015

Thanks to both Simon and Steve for their responses. After carefully reading
these responses, I am beginning to believe that rrdtool is selecting
consolidated values when the MAX samples required for the total are still in
the rrd file. Below are some more facts that may help shed some light on
this issue:

I am using RRDtool 1.3.8.

The RRA definition for all the files involved includes a MAX CDEF.
All the files have one-minute samples.
The one-minute MAX samples are still in the rrd files for the timeframe
(10/18/2015 @ 13:56) of the original posting.

I am including a copy of the cacti graph definition below (edited with 'ABC'
to hide customer names). It is clear to me that the rrdtool is simply adding
all the MAX values.
