[Perfparse-users] Router traffic counters

[Ciro I. <cy...@gm...>]

Hi,
    I'm running v106.1 and tried to collect traffic and error statistics
from our rounters with a nagios plugin, but it returns the current value of
the counter (well, as it should), the problem is that perfparse doesn't
calculate the difference between the current value and the last one (like
rrdtool) does, is there any way to make perfparse graph something useful
about this?, right now i only have a constant line (possitive value) in the
errors graphic and a curve going from 0 to the maximun value of the counter
on the traffic one.
    This is the only major drawback that i found on perfparse, would be
really great if there's any known workaround.

Thanks in advanced
Ciro
