[ProgSoc] Stuffed RRD files

[Martin Gisch <martin@nospam.progsoc.uts.edu.au>]

Anyone here familiar with rrdtool?

Scenario: You have a heap of .rrd files with data you'd much like to keep,
but in an effort to fix a different problem, you've accidentially
introduced a massive spike into the data sets for all of them, resulting
in output values such as 436.2Pbps (Thats Peta bits). All other areas of
graphs now naturally don't show up on that scale anymore.

Is there an easy way to detect & remove/smooth data points like this? The
rrd's don't have max/min values set or this may have been prevented...

It is fixable through a very manual process of dump to xml, edit xml and
fix values, restore into rrd...but I need a more automated way of doing
this.

Thanks if anyone has ideas...
