Apparently, your reply got lost somewhere in the backwaters of my

As of now, RRDCacheD does not support to create any RRD files on it's
own (i.e. rrdcreate is not supported by the caching daemon).
The only sensible approach I can think of how to fix that, would be to
run collectd on your central server. Then, do not send to RRDCacheD
directly but use the collectd network plugin to transfer the traffic
using the collectd network protocol (from a collectd client to the
collectd server). That central collectd server could then send all
values to RRDCacheD and take care of creating any new files (set the
"CreateFiles" config option to "true").
It might make sense to mention that option in the manpage … any
