Happy new year from here, too.

Nice to see your activity in this area - is this related to the Holt-Winters
mechanism available in rrd ? If I remember correct, those uses a periodic
variation
with an additional linear part.
Another question: Is the usage of carbon-cache (from graphite) as perfdata
storage
for the forecasting thinkable ?
At the moment we use our modules at https://bitbucket.org/hlauer/shinken2rrd to
put our
perfdata from shinken into carbon-cache (besides other sources using the same
minimalistic
udp protocol).
If there is interrest in adding the two broker modules (as asked some time ago)
I will
happily change the name of the modules.
Thanks and greetings,
Hermann
P.S: This time only one typo attached ;-)
