Hi,
My first post in the list, i have been reading it for a long time though.
Could this be caused my the heartbeat interval set in the rrd files ?
I don’t know of the code, takes the configured poll period into account when
creating the rrd files.
If it des you could try to configure a new source, which the should have
freshly created red files with the correct period.
The statistics timeslots probably give you the average over 5 periods.
You could verify this by inspecting the red files with rrdtool directly….
Med venlig hilsen / Kind Regards
