[ixpmanager] IXPM 5.3 Regenerate Yearly Traffic Graph

[Nick Hilliard (INEX)]

Hi Remy,

RRD stores separate archives for maximum and average time series, 
calling them "MAX" and "AVERAGE" respectively;  the API pulls data from 
the AVERAGE archive.

The peaks that are showing up in your graph are dark green, which means 
that they use data from the "MAX" archive.

If you manually run rrdtool dump on that RRD, you should run a text 
search for the line which starts "<cf>MAX</cf>".  The spike values will 
be contained in the following <database> archive.  You will probably 
need to manually edit these, then recreate the RRD archive.

Removing spikes from RRD files is a bit of a nuisance.
