To expand on the need: I want to store total bytes per hour (or minute)
per IP address. This collection is already in place, and I'm logging it
to a text file, but of course that leaves me with handling all the
aggregation and truncation of history that rrdtool already solves.
So I will need to manage the allocation of IP addresses to rrds in my
front end, and creating the rrd for a new ip address.
I initially want this for my home network, a mere handful of addresses,
which shouldn't be a size or processing problem (obviously I can't keep
per-minute data for a year). But I'd like to extend it to the office
environment which is much larger. But not enterprise-class, no.
Alex: you mentioned having several buckets in one RRD. Since I'll need
to allow for multiple rrds anyway, is there any advantage in having say
3 rrds with 10 addresses in each rather than 30 rrds? (Which would be
easier to manage.)
